The outcoming result shows that when the hea vy WIMP decays in a very non-relativistic speed\, the abundance is given b y a power of temperature in contrast to the usual Boltzmann suppressed exp onential. This has a great impact on the SUSY dark matter parameters.\n\nh ttp://indico.cern.ch/conferenceDisplay.py?confId=a034730 LOCATION:CERN TH Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a034730 END:VEVENT BEGIN:VEVENT SUMMARY:Bounds on New Physics from Parity Violation in Atomic Cesium DTSTART;VALUE=DATE-TIME:19990721T120000Z DTEND;VALUE=DATE-TIME:19990721T121500Z DTSTAMP;VALUE=DATE-TIME:20130524T202230Z UID:indico-event-a034731@cern.ch DESCRIPTION:Assuming the latest experimental determination of the weak cha rge of atomic cesium we analyze its implications for possible new physics. We notice that the data would imply positive upper and lower bounds on t he new physics contribution to the weak charge\, dNQW. The required new ph ysics should be of a type not severely constrained by the high energy prec ision data. A simplest possibility would be new neutral vector bosons almo st unmixed to the Z and with sizeable couplings to fermions. The lower pos itive bound would however forbid zero or negative dNQW and exclude not onl y the standard model but also models with sequential Z’in particular simp le-minded towers of Z-like excitations from extra-dimensions. The bound wo uld also imply an upper limit on the Z’ mass within the models allowed. C onclusions are also derived for models of four-fermion contact interaction s.\n\nhttp://indico.cern.ch/conferenceDisplay.py?confId=a034731 LOCATION:CERN TH Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a034731 END:VEVENT BEGIN:VEVENT SUMMARY:Neutrino masses and neutrino mixings DTSTART;VALUE=DATE-TIME:19990728T120000Z DTEND;VALUE=DATE-TIME:19990728T121500Z DTSTAMP;VALUE=DATE-TIME:20130524T202230Z UID:indico-event-a034732@cern.ch DESCRIPTION:I summarise how I view the present situation concerning neutri no masses and mixings\, including the attempts to find a rationale in the pattern seemingly observed by experiments so far.\n\nhttp://indico.cern.ch /conferenceDisplay.py?confId=a034732 LOCATION:CERN TH Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a034732 END:VEVENT BEGIN:VEVENT SUMMARY:The Parton Structure of the Proton: Present Status and Future Pers pectives DTSTART;VALUE=DATE-TIME:19990804T120000Z DTEND;VALUE=DATE-TIME:19990804T133000Z DTSTAMP;VALUE=DATE-TIME:20130524T202230Z UID:indico-event-a034733@cern.ch DESCRIPTION:The short-distance quark and gluon structure of the proton can be quantified in terms of parton distributions functions\, fi(x\,Q2). At present\, the most precise information on these functions comes from a glo bal fit to a wide variety of high-energy lepton-hadron and hadron-hadron c ollision data. I will review the current knowledge on parton distribution functions\, and show how they reveal an interesting non-perturbative struc ture to the quark-antiquark sea which is not fully understood. I will also discuss the role of parton distribution functions at the LHC.\n\nhttp://i ndico.cern.ch/conferenceDisplay.py?confId=a034733 LOCATION:CERN TH Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a034733 END:VEVENT BEGIN:VEVENT SUMMARY:Scattering and locality in the AdS/CFT correspondence DTSTART;VALUE=DATE-TIME:19990811T120000Z DTEND;VALUE=DATE-TIME:19990811T121500Z DTSTAMP;VALUE=DATE-TIME:20130524T202230Z UID:indico-event-a034734@cern.ch DESCRIPTION:A crucial - and profound - question in the AdS/CFT \ncorrespon dence regards the emergence of approximate locality in \nthe bulk. This qu estion drives at the essence of the holographic \nproposal. To investigate this question\, one first needs a means of \nextracting information in th e bulk theory from the boundary CFT. \nI'll discuss some of the issues in deriving a flat-space S-matrix \nfrom the CFT\, and will also give some pr eliminary discussion \nabout how bulk locality might be tested.\n\nhttp:// indico.cern.ch/conferenceDisplay.py?confId=a034734 LOCATION:CERN TH Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a034734 END:VEVENT BEGIN:VEVENT SUMMARY:Instantons in SUSY Yang-Mills and string theory DTSTART;VALUE=DATE-TIME:19990825T120000Z DTEND;VALUE=DATE-TIME:19990825T121500Z DTSTAMP;VALUE=DATE-TIME:20130524T202230Z UID:indico-event-a034735@cern.ch DESCRIPTION:String theory has long suggested deep connections between Yang -Mills theory (open strings) and general relativity (closed strings).

Ul tra-high energy cosmic ray and neutrino production in GRBs will be discuss ed in the light of recent cosmic-ray observations and of new constraints i mposed by observations on GRB models.\n\nEmphasis will be placed on model predictions that can be tested with operating and planned large scale\, hi gh-energy cosmic ray and neutrino detectors.\n\nhttp://indico.cern.ch/conf erenceDisplay.py?confId=a034737 LOCATION:CERN TH Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a034737 END:VEVENT BEGIN:VEVENT SUMMARY:Creation of matter after inflation\n DTSTART;VALUE=DATE-TIME:19990915T120000Z DTEND;VALUE=DATE-TIME:19990915T121500Z DTSTAMP;VALUE=DATE-TIME:20130524T202230Z UID:indico-event-a034738@cern.ch DESCRIPTION:According to inflationary theory\, all matter in the universe was created in the process of reheating after inflation. Recently it was r ealized that reheating is a nonperturbative effect which often involves cr eation of particles in the process of parametric resonance. This process\, which is called 'preheating\,' is especially efficient if the created par ticles are bosons\, but nonperturbative production of fermions is also pos sible. We will describe the mechanism of instant preheating which may lead to production of particles with masses up to the Planck mass 1019 GeV. We will also discuss the theory of nonthermal phase transitions induced by p reheating\, and the problem of overproduction of gravitinos and other dang erous relics.\n\nhttp://indico.cern.ch/conferenceDisplay.py?confId=a034738 LOCATION:CERN TH Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a034738 END:VEVENT BEGIN:VEVENT SUMMARY:Chiral symmetry breaking in QCD and Ginsparg-Wilson fermions DTSTART;VALUE=DATE-TIME:19990922T120000Z DTEND;VALUE=DATE-TIME:19990922T121500Z DTSTAMP;VALUE=DATE-TIME:20130524T202230Z UID:indico-event-a034739@cern.ch DESCRIPTION:A natural candidate for studying the non-perturbative phenomen on of spontaneous chiral symmetry breaking in QCD is the numerical simulat ion of QCD on a space-time lattice. This phenomenon\, however\, confronts the lattice approach with a twofold challenge. The first problem is that s pontaneous symmetry breaking does not occur in a finite volume. We circumv ent this problem by performing a \nfinite-size scaling analysis which invo lves placing the system in a large enough box and confronting the dependen ce of the quark condensate on volume and quark mass to predictions from ch iral perturbation theory\, as the limit of restoration of chiral symmetry is approached \n(m-> 0\, V finite). Such a study\, however\, requires cont rolling the chiral behaviour of the theory well\, which is \ndifficult on a discrete space-time. To address this second challenge\, we turn to Ginsp arg-Wilson fermions\, which have recently been shown to possess a continuu m-like chiral symmetry.\n\nhttp://indico.cern.ch/conferenceDisplay.py?conf Id=a034739 LOCATION:CERN TH Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a034739 END:VEVENT BEGIN:VEVENT SUMMARY:A supergravity view of string dualities\n DTSTART;VALUE=DATE-TIME:19990929T120000Z DTEND;VALUE=DATE-TIME:19990929T121500Z DTSTAMP;VALUE=DATE-TIME:20130524T202230Z UID:indico-event-a034740@cern.ch DESCRIPTION:The seminar will review recent explicit constructions of strin g duality relations in the context of general supergravity backgrounds\, i ncluding Ramond-sector fields. Insistence on geometrically covariant const ructs is repaid by a much greater transparency of the action of string dua lities. Specific cases to be discussed will be details of the IIA/IIB T-du ality\, and the relationship between M-theory and the \nmassive IIA theory needed for the existence of domain walls.\n\nhttp://indico.cern.ch/confer enceDisplay.py?confId=a034740 LOCATION:CERN TH Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a034740 END:VEVENT BEGIN:VEVENT SUMMARY:Logarithmic gauge unification in TeV-scale string theories \n DTSTART;VALUE=DATE-TIME:19991006T120000Z DTEND;VALUE=DATE-TIME:19991006T121500Z DTSTAMP;VALUE=DATE-TIME:20130524T202230Z UID:indico-event-a034741@cern.ch DESCRIPTION:http://indico.cern.ch/conferenceDisplay.py?confId=a034741 LOCATION:CERN TH Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a034741 END:VEVENT BEGIN:VEVENT SUMMARY:Chiral lattice gauge theories with exact gauge invariance\n DTSTART;VALUE=DATE-TIME:19991110T130000Z DTEND;VALUE=DATE-TIME:19991110T131500Z DTSTAMP;VALUE=DATE-TIME:20130524T202230Z UID:indico-event-a034742@cern.ch DESCRIPTION:It has recently become clear that chiral symmetry can be exact ly \npreserved in lattice gauge theory\, without violating fundamental \np rinciples or having more fermions than intended. As a result it is now pos sible to set up chiral gauge theories on the lattice in a theoretically ap pealing way. Particular attention will be paid to the cancellation of the anomaly and its interpretation in terms of local cohomology.\n\nhttp://ind ico.cern.ch/conferenceDisplay.py?confId=a034742 LOCATION:CERN TH Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a034742 END:VEVENT BEGIN:VEVENT SUMMARY:Tachyon-free non-supersymmetric type I string vacua from brane-ant ibrane systems\n DTSTART;VALUE=DATE-TIME:19991117T130000Z DTEND;VALUE=DATE-TIME:19991117T131500Z DTSTAMP;VALUE=DATE-TIME:20130524T202230Z UID:indico-event-a034743@cern.ch DESCRIPTION:Compactifications of Type I string vacua to four dimensions ha ve several phenomenologically interesting features. In particular\, they p rovide an explicit realization of consistent models where \ngauge theory s ectors can be localized on D-branes\, while gravity and other fields propa gate over all of spacetime. In this talk I will first review the construct ion of toroidal orbifolds of type I \nstring theory\, and discuss their co nsistency conditions (cancellation of tadpoles). I will show it is possibl e to construct consistent models which contain D-branes and anti-D-branes\ , but are \nnevertheless stable against decay by brane-antibrane annihilat ion. These models are non-supersymmetric but free of tachyons. In many exa mples\, supersymmetry is preserved at lowest order in the bulk and in D-br ane 'visible' sectors\, while sypersymmetry is broken at the \nstring scal e in 'hidden' anti-D-brane sectors. Models with realistic 'visible' sector s can be easily constructed. Finally\, these configurations raise interest ing questions concerning the \ndynamics of the compactification moduli and the dilaton\, which have non-trivial potentials due to the lack of supers ymmetry.\n\nhttp://indico.cern.ch/conferenceDisplay.py?confId=a034743 LOCATION:CERN TH Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a034743 END:VEVENT BEGIN:VEVENT SUMMARY:CP violation: challenge and hope for low-energy SUSY\n DTSTART;VALUE=DATE-TIME:19991124T130000Z DTEND;VALUE=DATE-TIME:19991124T131500Z DTSTAMP;VALUE=DATE-TIME:20130524T202230Z UID:indico-event-a034744@cern.ch DESCRIPTION:The presence of low-energy SUSY gives rise to new sources of C P violation and with it also to several questions. How severe are the CP c onstraints on (minimal and non-minimal) SUSY realizations? Could CP violat ion be a purely SUSY effect? To what extent CP violation in flavour-changi ng phenomena (for instance in the kaon system) probes the possible link be tween SUSY breaking and origin of the flavour? \nAnd\, even more important \, can we still hope to have some SUSY signal in CP violating phenomena? W hile trying to answer (some of) the above questions\, the talk aims to sho w that if it is true that CP represents a serious concern for low-energy S USY\, at the same time it could provide some precious clues in the search for SUSY hints.\n\nhttp://indico.cern.ch/conferenceDisplay.py?confId=a0347 44 LOCATION:CERN TH Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a034744 END:VEVENT BEGIN:VEVENT SUMMARY:Entropy bounds\, string cosmology and our arrow of time\n DTSTART;VALUE=DATE-TIME:19991201T130000Z DTEND;VALUE=DATE-TIME:19991201T150000Z DTSTAMP;VALUE=DATE-TIME:20130524T202230Z UID:indico-event-a034745@cern.ch DESCRIPTION:Old and new proposals for entropy bounds are briefly reviewed and compared. In string cosmology\, the relevant bound is threatened by qu antum entropy production during pre-big bang inflation\, making the eventu al transition to a FRW Universe necessary. The rapid increase of the bound in this latter phase appears to provide our present arrow of time.\n\nhtt p://indico.cern.ch/conferenceDisplay.py?confId=a034745 LOCATION:CERN TH Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a034745 END:VEVENT BEGIN:VEVENT SUMMARY:The holographic principle\n DTSTART;VALUE=DATE-TIME:19991215T130000Z DTEND;VALUE=DATE-TIME:19991215T131500Z DTSTAMP;VALUE=DATE-TIME:20130524T202230Z UID:indico-event-a034746@cern.ch DESCRIPTION:We present a universal upper bound on entropy. It is covariant and applies to surfaces of any shape\, open or closed\, at any place and time in all physical space-times. In particular\, it remains valid in the interior of black holes and in all FRW cosmologies. It reduces to Bekenste in's bound whenever the latter is expected to hold. The new bound leads us to a generalised formulation of 't Hooft's \nholographic hypothesis. We p resent an explicit construction for obtaining holographic screens in arbit rary space-times. Thus our formulation aims to establish the holographic p rinciple not as a property only of static systems and of certain space-tim es\, but as a truly universal law.\n\nhttp://indico.cern.ch/conferenceDisp lay.py?confId=a034746 LOCATION:CERN TH Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a034746 END:VEVENT BEGIN:VEVENT SUMMARY:Lattice QCD using domain wall quarks\n DTSTART;VALUE=DATE-TIME:20000112T130000Z DTEND;VALUE=DATE-TIME:20000112T150000Z DTSTAMP;VALUE=DATE-TIME:20130524T202230Z UID:indico-event-a034748@cern.ch DESCRIPTION:I review recent quenched lattice QCD calculations that use a n ew method for treating fermions\, which preserve chiral symmetry at non-ze ro lattice spacing\, up to exponentially small corrections.

A convincing\, background independent and fully general r elativistic quantum field theory\, capable of describing quantum space-tim e is still lacking. I briefly review successes and \ndifficulties of the m ajor current approaches to the problem (strings\, loops\, non-commutative geometry\, etc.)\, and then focus on the loop approach. I illustrate the b asics of loop quantum gravity\, the picture of quantum space-time it provi des\, and its main physical successes: the computation of the Planck scale spectra of area and volume\, and of the Bekenstein-Hawking black hole ent ropy. I then describe recent developments in the covariant formulation of loop quantum gravity: the spin foam formulation\; and a surprising converg ence between the loop \nformalism and topological quantum field theory.\n\ nhttp://indico.cern.ch/conferenceDisplay.py?confId=a034750 LOCATION:CERN TH Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a034750 END:VEVENT BEGIN:VEVENT SUMMARY:Resummation of singlet structure functions at small x\n DTSTART;VALUE=DATE-TIME:20000202T130000Z DTEND;VALUE=DATE-TIME:20000202T150000Z DTSTAMP;VALUE=DATE-TIME:20130524T202230Z UID:indico-event-a034751@cern.ch DESCRIPTION:The data at small x collected at HERA show a very good agreeme nt with the QCD evolution equations at two loops. However this agreement i s somewhat surprising because neglected terms down by powers of [a ln(1/x) ] could be important. The BFKL approach designed to control these terms\, at first sight leads to a very unstable expansion. We propose an improvem ent of the splitting functions at small x\, which overcomes the apparent p roblems encountered by the BFKL approach. We finally obtain an expansion o f the splitting function\, which leads to good apparent convergence and to a description of scaling violations \nvalid both at large\, and small x.\ n\nhttp://indico.cern.ch/conferenceDisplay.py?confId=a034751 LOCATION:CERN TH Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a034751 END:VEVENT BEGIN:VEVENT SUMMARY:Weak scale strings and extra dimensions\n DTSTART;VALUE=DATE-TIME:20000209T130000Z DTEND;VALUE=DATE-TIME:20000209T131500Z DTSTAMP;VALUE=DATE-TIME:20130524T202230Z UID:indico-event-a034752@cern.ch DESCRIPTION:I will discuss some issues related to the scenario of weak sca le strings.

They will be e xplored with unprecedented scope and precision by numerous experiments in the near future. The most important theoretical problem in describing thes e processes is the evaluation of hadronic matrix elements of the effective weak Hamiltonian. Using B Æpp as an example\, we discuss a framework tha t was recently proposed to address this problem in QCD in the heavy quark limit. We argue that the matrix elements factorise to leading power in LQC D/mb\, with calculable QCD corrections\, which are computed to O (as).

It is found that the size of a typical self-gravi tating string state of mass M shrinks when g increases\, and becomes compa rable to its Schwarzschild radius when g2 M ~ Mstring. Such a compact stri ng state has (in order of magnitude) the correct number of states to match the Bekenstein- Hawking entropy of a black hole. (Ref.: T. Damour and G.

The number of degrees o f freedom is the same as the d dimensional theory thanks to gauge symmetri es that tend to reduce the number of effective dimensions. The gauge fixin g is done with different embeddings of d dimensions inside d+2 dimensions\ , such that a reshuffling of the degrees of freedom produces different 1T dynamical systems (different Hamiltonians) from the same 2T theory\, and p rovides a new type of unification among different d- dimensional dynamical systems. The 2T approach implies the existence of a more subtle higher st ructure of dimensional unification with a SO(d\,2) covariance (or more gen eral d+2 symmetry) that exists in many 1T systems\, but which remained hid den until discovered via the 2T formalism. 2T physics has mainly been deve loped in the context of particles\, but some advances have also been made with strings and p-branes\, and some insights for M-theory have already em erged. In the case of particles\, there exists a general worldline formula tion with background fields\, as well as a field theory formulation\, both described in terms of fields that depend on d+2 co-ordinates. All particl e interactions with Yang-Mills\, gravitational and other fields are includ ed in this reformulation\, so that the Standard Model of particle physics may be regarded as a gauge fixed form of a 2T theory.\n\nhttp://indico.cer n.ch/conferenceDisplay.py?confId=a034756 LOCATION:CERN TH Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a034756 END:VEVENT BEGIN:VEVENT SUMMARY:Generalized Hall effects and the chiral anomaly\n DTSTART;VALUE=DATE-TIME:20000621T120000Z DTEND;VALUE=DATE-TIME:20000621T143000Z DTSTAMP;VALUE=DATE-TIME:20130524T202230Z UID:indico-event-a034761@cern.ch DESCRIPTION:Experimental results on quantized conductance in 2D electron g ases and in quantum wires are reviewed.

In many cases the corresponding vacuum manifold has non-trivial homotopies which gives rise to topological ly stable defects in four dimensions\, such as cosmic strings and monopole s that carry gravimagnetic flux. The core structure of these defects is so mewhat peculiar. Due to the fact that the translation invariance in the ex tra dimension is restored in their core\, they can serve as windows to ext ra dimensions. An analogue of the Alice string is discussed.

After a brief overview of th e standard model of nucleosynthesis in the framework of big bang cosmology \, I will review the current status of the observations of the light eleme nt isotopes and efforts to determine the primordial abundance of these ele ments. The Latter depends on galactic chemical evolution\, which affects t he abundance of the elements over the history of the Galaxy. The abundance of Li is sensitive to the production of light elements in the Galaxy by c osmic-ray nucleosynthesis which is responsible for the isotopes 6Li\, 9Be\ , 10\,11B in addition to 7Li.

These azimuthal anisotr opies\, referred to as 'flow'\, have been measured in ultrarelativistic co llisions at the CERN SPS\, and at RHIC (Brookhaven) last summer. The reaso n why flow is an interesting observable is that it results from the compre ssion of the matter produced in the collision: it is therefore highly sens itive to the equation of state of nuclear matter at high temperature. Most of this talk will focus on the methods used to measure the flow: since th e impact direction of the incoming nucleus is unknown\, measuring the corr elation of outgoing particles with this direction is a non-trivial task.

Sys tems where the binding force arises from a 1/r Coulombic potential are of special interest as many systems in QED (hydrogen\, positronium\, etc.) an d QCD (heavy quarkonia\, top pair production at threshold at a lepton pair collider) can be examined experimentally with high precision. For decades precise higher order calculations had been reserved to a few specialists using the Bethe-Salpeter formalism. Caswell and Lepage first advocated the idea to describe non-relativistic Coulombic systems with effective field theories using the hierarchy between the constituent mass m \, momentum mv and energy mv2 \, where v$ is the velocity. Nevertheless\, calculations i n Lepage's theory remained difficult as a complete separation of scales (a nd a consistent power counting) had not been achieved. One of the problems was that the momentum scale mv and the energy scale mv2\, although widely separated from each other\, were tied together via the equation of motion -- a feature also known from heavy quark decays and finite temperature th eory. A series of publications by many authors in the years 1997--1999 fin ally paved the way to an effective field theory formulation (called vNRQCD ) that provides a consistent power counting and resolves the issue of corr elated scales. vNRQCD provides powerful tools such as the renormalization group that make it to much more than a reformulation of the old Bethe-Salp eter formalism. These tools are essential for a precise description of non -relativistic top-antitop pairs produced at a lepton pair collider.\n\nhtt p://indico.cern.ch/conferenceDisplay.py?confId=a034785 LOCATION:CERN TH Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a034785 END:VEVENT BEGIN:VEVENT SUMMARY:Intermediate scale string phenomenology DTSTART;VALUE=DATE-TIME:20001213T130000Z DTEND;VALUE=DATE-TIME:20001213T140000Z DTSTAMP;VALUE=DATE-TIME:20130524T202230Z UID:indico-event-a034774@cern.ch DESCRIPTION:Some recent string models have the string scale at 1011 GeV in order to explain the SUSY breaking scale naturally.

This new way of embedding gauge theories into string theory is very attractive partly because it allows for a string tension as low as 1TeV. On the other hand\, any brane realization of the world easily accom modates non-classical field theories in which space is quantized ('non-com mutative field theories'). If the latter were realized in our 4-dimensiona l space-time they would break Lorentz symmetry and show up e.g. in small c orrections to the angular distribution of scattering experiments. But even if such effects turn out not to be very relevant\, brane non-commutativit y in unseen dimensions can have important consequences on the observed wor ld. I will discuss how various types of non-commutative field theories ari se from string theory\, including so-called 'fuzzy gauge theories'. The la tter control brane dynamics in many string backgrounds and they have inter esting implications on brane stabilization and bound state formation.\n\nh ttp://indico.cern.ch/conferenceDisplay.py?confId=a034792 LOCATION:CERN TH Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a034792 END:VEVENT BEGIN:VEVENT SUMMARY:Muon g-2: probe of physics at short distances DTSTART;VALUE=DATE-TIME:20010425T120000Z DTEND;VALUE=DATE-TIME:20010425T130000Z DTSTAMP;VALUE=DATE-TIME:20130524T202230Z UID:indico-event-a034801@cern.ch DESCRIPTION:Standard Model contributions to the muon anomalous magnetic mo ment (QED\, hadronic\, and electroweak loop effects) will be reviewed\, wi th special attention to the uncertainties in the theoretical prediction.

Such a field may develo p an (approximately stable) network of domain walls. The domain wall thick ness is assumed to be comparable with the thickness of the luminous part o f the spiral galaxies. The walls provide trapping for galactic matter. Thi s is used to motivate the very existence of the spiral galaxies. A zero mo de existing on the domain wall is a massless scalar particle confined to 1 +2 dimensions. At distances much larger than the galaxy/wall thickness\, t he zero-mode exchange generates a logarithmic potential\, acting as an add itional term with respect to Newton's gravity. The logarithmic term natura lly leads to constant rotational velocities at the periphery. We estimate the scalar field coupling to the matter energy-momentum tensor needed to f it the observable flat rotational curves of the spiral galaxies. The value of this coupling turns out to be reasonable -- we find no contradiction w ith the existing data.\n\nhttp://indico.cern.ch/conferenceDisplay.py?confI d=a034819 LOCATION:CERN TH Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a034819 END:VEVENT BEGIN:VEVENT SUMMARY:QCD factorization and rescattering in nuclear collisions DTSTART;VALUE=DATE-TIME:20011010T120000Z DTEND;VALUE=DATE-TIME:20011010T130000Z DTSTAMP;VALUE=DATE-TIME:20130524T202230Z UID:indico-event-a034811@cern.ch DESCRIPTION:Much of the predictive content of perturbative QCD is containe d in factorization theorems.

Theoretical explanations range from astrophysical acceleration of charged particles to particle physics beyond the established Standard M odel\, and processes taking place at the earliest moments of our Universe. Distinguishing between these scenarios requires on the one hand cosmic ra y detectors with effective areas in \nthe 1000 km2 range which are now und er construction.

This allows to have the fundamental scale of new physics as low as a fe w TeV in which case supersymmetry is no more required in order to protect the gauge hierarchy.

Furthermore\, the appropriate fo rmulation of the higher-dimensional supersymmetry in terms of 4d superfiel ds will be discussed in some detail.\n\nhttp://indico.cern.ch/conferenceDi splay.py?confId=a034833 LOCATION:CERN TH Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a034833 END:VEVENT BEGIN:VEVENT SUMMARY:Spectrum of confining strings in SU(N) gauge theories DTSTART;VALUE=DATE-TIME:20020220T130000Z DTEND;VALUE=DATE-TIME:20020220T140000Z DTSTAMP;VALUE=DATE-TIME:20130524T202230Z UID:indico-event-a034834@cern.ch DESCRIPTION:The string tensions sk related to sources with ZN charge k are computed using Monte Carlo simulations for the SU(4) and SU(6) gauge theo ries formulated on a lattice. Our results are consistent with the sine for mula sk/s = sin(k p/N) / sin(p/N)\, within a few per cent accuracy\, and s how sizeable deviations from the Casimir scaling. We confront this result with various realisations of supersymmetric SU(N) gauge theories where the sine formula is known to emerge.

Although the transition of strongly interacti ng matter to the quark gluon plasma occurs in a well defined narrow temper ature interval around 170 MeV it most likely does not correspond to a true phase transition. The early universe thus avoided to go through a phase t ransition not only at the electroweak but also at the strong scale. We wil l discuss our current understanding of the QCD phase diagram\, present res ults from lattice calculations that emphasise deconfining and chiral symme try restoring aspects of the transition to the QGP and stress the importan ce of copious resonance production for the onset of the transition. Therma l modifications of resonance parameters\, which can be calculated on the l attice\, lead to characteristic changes in experimentally observable dilep ton spectra.\n\nhttp://indico.cern.ch/conferenceDisplay.py?confId=a034835 LOCATION:CERN TH Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a034835 END:VEVENT BEGIN:VEVENT SUMMARY:Jet tomography of soft QCD matter at RHIC and LHC DTSTART;VALUE=DATE-TIME:20020313T130000Z DTEND;VALUE=DATE-TIME:20020313T140000Z DTSTAMP;VALUE=DATE-TIME:20130524T202230Z UID:indico-event-a034840@cern.ch DESCRIPTION:Rare hard jets produced in ultra-relativistic nuclear collisio ns at RHIC and LHC provide new 'tomographic' tools to image the density ev olution of the transient quark gluon plasma produced in those reactions. I will review recent theoretical developments on the problem of gluon radia tive energy loss in QCD matter and discuss our first attempts to apply tha t theory to the analysis of the latest data from RHIC. Our analysis of the jet quenching pattern reported by STAR and PHENIX for Au (70 AGeV) + Au ( 70 AGeV) -> 5000 hadrons suggests that the the initial densities of the pl asmas may have reached ~ 100 times that of ordinary nuclei.

For the afterglows - on which I shall concentrate - our understanding\, based on the 'Cannon ball model'\, is extraordinarily simple\, precise and successful.

In addition\, the baryon asymmetry of the universe can be gene rated in out-of-equilibrium decays of the heavy neutrinos. If the \nworld is supersymmetric\, the neutrino data also indicates the observable rates of the lepton flavour violating decays (LFV) and electric dipole moments ( EDM) of charged leptons. After reviewing the current situation in the fiel d\, I present a new parametrization of the heavy neutrino Yukawa couplings and masses which automatically satisfy the neutrino oscillation data. Thi s allows us to perform a completely model-independent phenomenological stu dy of the LFV tau-lepton and muon decays and EDM-s of the electron and the muon in this framework\, and to correlate them with leptogenesis and neut rinoless double beta decay constraints. It is important to search for LFV tau decays at LHC experiments\, and especially to improve the experimental sensitivity to the EDM of the electron.\n\nhttp://indico.cern.ch/conferen ceDisplay.py?confId=a034837 LOCATION:CERN TH Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a034837 END:VEVENT BEGIN:VEVENT SUMMARY:Testing cosmological defect formation in the laboratory DTSTART;VALUE=DATE-TIME:20020426T121500Z DTEND;VALUE=DATE-TIME:20020426T131500Z DTSTAMP;VALUE=DATE-TIME:20130524T202230Z UID:indico-event-a033381@cern.ch DESCRIPTION:Topological defects such as cosmic strings may have been forme d at early-universe phase transitions. To predict their effects we need to estimate what types of defects are formed and how many. We cannot directl y test whether our estimates are reliable\, but we can test our methods by studying analogous processes in low-temperature condensed-matter systems.

All errors are c ontrolled\, with the exception of the quenched (or valence) approximation. In particular\, renormalization and O(alpha) improvement are implemented non-perturbatively\, and the continuum limit is taken. For fixed experimen tal input the total error for the charm quark mass is around 4 percent\, w hich is clearly smaller than the quenching error. A first idea of the latt er is obtained by allowing for a 'quenched scale ambiguity' of 10 percent\ , which induces a shift of about 8 percent in the charm quark mass.\n\nhtt p://indico.cern.ch/conferenceDisplay.py?confId=a034838 LOCATION:CERN SL Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a034838 END:VEVENT BEGIN:VEVENT SUMMARY:Geometric origin of large neutrino mixing in a higher-dimensional space-time DTSTART;VALUE=DATE-TIME:20020605T120000Z DTEND;VALUE=DATE-TIME:20020605T130000Z DTSTAMP;VALUE=DATE-TIME:20130524T202230Z UID:indico-event-a034846@cern.ch DESCRIPTION:The large mixing in the lepton sector observed in the recent n eutrino-oscillation experiments strongly suggest that nature of left-hande d lepton doublets is very different from that of left-handed quark doublet s.

We show that this big differenc e can be explained in a six-dimensional space-time compactified on the T2/ Z3 orbifold.

I will concentrate on two k ey observations which go qualitatively beyond what was seen at the CERN SP S: the strong `elliptic flow' measured in non-central Au+Au collisions\, a nd the observation of `jet quenching'. The elliptic flow requires fast the rmalization of the hot matter produced in the collision within less than 1 fm/c\, followed by almost ideal hydrodynamic expansion. The initial energ y density of the thermalized state is more than an order of magnitude abov e the critical value for hadronization\, and the thermalized quark-gluon p lasma (QGP) lives for about 5 fm/c before beginning to hadronize. The QGP seems to efficiently suppress jets from hard-scattered partons. The observ ed `soft' scaling of `hard' hadron production together with a complete sup pression of 180 degree azimuthal angular correlations in central Au+Au col lisions are consistent with `complete jet quenching': hard hadrons are emi tted only from a thin surface layer of the hot fireball.\n\nhttp://indico. cern.ch/conferenceDisplay.py?confId=a034856 LOCATION:CERN TH Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a034856 END:VEVENT BEGIN:VEVENT SUMMARY:Higgs phenomenon for the anti-de Sitter graviton\n\n DTSTART;VALUE=DATE-TIME:20020828T120000Z DTEND;VALUE=DATE-TIME:20020828T130000Z DTSTAMP;VALUE=DATE-TIME:20130524T202230Z UID:indico-event-a034855@cern.ch DESCRIPTION:We show that standard Einstein gravity coupled to a free confo rmal field theory (CFT) in Anti de Sitter space can undergo a Higgs phenom enon whereby the graviton acquires a nonzero mass and three extra polariza tions.

This perturbative computation reduces to a matrix model whose action is the tre e-level superpotential. The exact large N solution is encoded in the geome try of a Calabi-Yau manifold. These results are obtained without assuming any conjectured dualities and can be used as a systematic method to comput e instanton effects using Feynman diagrams.

A promising tool to deal with these e ffects is offered by Bs -> K+K-\, which is very accessible at hadronic B e xperiments. A variant of this approach for the e+e- B-factories is provide d by Bd -> pi-/+ K+/-\, where data are already available\, pointing to an exciting picture.\n\nhttp://indico.cern.ch/conferenceDisplay.py?confId=a0 34860 LOCATION:CERN Council Chamber URL:http://indico.cern.ch/conferenceDisplay.py?confId=a034860 END:VEVENT BEGIN:VEVENT SUMMARY:EXACT RENORMALISATION GROUP FOR GAUGE THEORIES --- A STATUS REPORT DTSTART;VALUE=DATE-TIME:20021030T130000Z DTEND;VALUE=DATE-TIME:20021030T140000Z DTSTAMP;VALUE=DATE-TIME:20130524T202230Z UID:indico-event-a034866@cern.ch DESCRIPTION:Some of the important problems of fundamental particle physics are of a\ntruly non-perturbative nature.

We study field theoretic prototypes of D branes/strings. To this end we consider (2+1)-dimensional domain walls in (3+1)-dimension al N = 2 SQCD with SU(2) gauge group and N_f = 2 flavours of fundamental h ypermultiplets (quarks). This theory is perturbed by a small mass term of the adjoint matter which\, in the leading order in the mass parameter\, do es not break N = 2 supersymmetry\, and reduces to a (generalized) Fayet-Il iopoulos term in the effective low-energy N = 2 SQED. We find 1/2 BPS-satu rated domain wall solution interpolating between two quark vacua at weak c oupling\, and show that this domain wall localizes a U(1) gauge field. To make contact with the brane/string picture we consider the Abrikosov-Niels en-Olesen magnetic flux tube in one of two quark vacua and demonstrate tha t it can end on the domain wall. We find an explicit 1/4 BPS-saturated sol ution for the wall/flux tube junction. We verify that the end point of the flux tube on the wall plays the role of an electric charge in the dual 2+ 1 dimensional SQED living on the wall. Flow to N = 1 theory is discussed. Our results lead us to a conjecture regarding the notorious "missing wall" in the solution of Kaplunovsky et al.\n\nhttp://indico.cern.ch/conference Display.py?confId=a034711 LOCATION:CERN TH Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a034711 END:VEVENT BEGIN:VEVENT SUMMARY:Stitching the Yukawa quilt DTSTART;VALUE=DATE-TIME:20030305T130000Z DTEND;VALUE=DATE-TIME:20030305T140000Z DTSTAMP;VALUE=DATE-TIME:20130524T202230Z UID:indico-event-a034713@cern.ch DESCRIPTION:We discuss the implications for the Yukawa couplings of the St andard Model of the measurement of quark\, charged lepton and neutrino mas ses\, mixings and CP violation. The resultant structure is suggestive of a (broken) family symmetry and we consider what is the maximal symmetry whi ch\, when combined with a Grand Unified symmetry and the seesaw mechanism\ , is consistent with both the quark and lepton sectors. This naturally acc ommodates large mixing angles in the lepton sector and leads to new textur e zero predictions for the CHOOZ angle and CP violating phases. We constru ct a supersymmetric model of masses and mixings based on SO(10) together w ith an SU(3) family symmetry. In addition to giving a good description of the fermion sector it limits flavour changing processes through constraint s on the spectrum of squarks and sleptons. Spontaneous breaking of CP is e asily implemented via the flavon sector and gives a simple way of avoiding the SUSY CP problem.\n\nhttp://indico.cern.ch/conferenceDisplay.py?confId =a034713 LOCATION:CERN TH Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a034713 END:VEVENT BEGIN:VEVENT SUMMARY:The pressure of hot/dense QCD DTSTART;VALUE=DATE-TIME:20030312T130000Z DTEND;VALUE=DATE-TIME:20030312T140000Z DTSTAMP;VALUE=DATE-TIME:20130524T202230Z UID:indico-event-a034712@cern.ch DESCRIPTION:The free energy density\, or pressure\, of QCD\, as a function of temperature and baryon chemical potential\, is of principal relevance to cosmology\, the nearly ideal hydrodynamics observed in heavy ion collis ion experiments\, as well as compact star phenomenology.

Entanglement is\, thus\, controlled by conformal symmetry and Quantum information results can be translated from black hole physics. The lack o f saturation of entanglement as computed in field theory seems to limit th e success of the density matrix renormalization group technique. On the ot her hand\, the strong sense of order known as majorization seems to be und erlying renormalization group ideas. Entanglement scaling has been proven necessary for the efficiency of quantum algorithms. Quantum adiabatic evol ution as a technique for quantum computation numerically shows entanglemen t scaling for the 3-SAT problem.

Yet\, they h ave some two dozen common properties. The characteristic gamma-ray energy is surprisingly narrowly distributed around E = 250 keV. The energy spectr a are well fit by a specific "Band" function. The photons arrive in succes sive "pulses" which\, in "long" GRBs\, have a median width of 0.5 seconds. The polarization of the gammas is nearly maximal. Etc.\, etc.\, etc. Our detailed understanding of GRB "afterglows" in the "cannonball" (CB) model has taught us a lot about the properties of the medium surrounding the sta rs whose explosive supernova deaths generate GRBs\, and about the "ambient light" that permeates this medium. This\, in turn\, allows us to individu ate the phenomenon that generates a GRB pulse: the passage of a CB throug h the cited ambient light. This results in an extremely simple derivation of all GRB properties. And the ONLY key imput turns out to be Compton scat tering: the Mother of all particle-physics processes! The "accelerator" ac celerating CBs is also the mother of all accelerators (but the LHC?). Its theoretical understanding is the only obstacle separating the CB model fro m a complete theory of GRBs.\n\nhttp://indico.cern.ch/conferenceDisplay.py ?confId=a035142 LOCATION:CERN TH Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a035142 END:VEVENT BEGIN:VEVENT SUMMARY:Exceptional Theoretical Seminar: Cosmological fluctuations and con servation laws DTSTART;VALUE=DATE-TIME:20030915T143000Z DTEND;VALUE=DATE-TIME:20030915T153000Z DTSTAMP;VALUE=DATE-TIME:20130524T202230Z UID:indico-event-a035208@cern.ch DESCRIPTION:In order to use observations of the anisotropy and polarizatio n of the cosmic microwave background to learn about inflation\, it is nec essary to rely on conservation laws that apply outside the horizon.

Giving up the assumption that cold dark matter is a dissipationless fluid allows us to describe the observations without dark energy and suggests a link between the phenomenon of dark energy and the formation of non-linear structures.

It is found that a high matter density model fits all these surveys remarkably well\, in agreement with all existing previous analyse s following the same strategy.

Light fermions m ay arise naturally as states localized on a domain wall. Hence\, the exist ence of fermions far below the Planck scale may be a concrete hint to the physical reality of extra dimensions. D-theory is an alternative non-pertu rbative approach to field quantization in which continuous classical field s arise via dimensional reduction of discrete variables. For example\, glu on fields emerge as collective excitations of discrete quantum links - gau ge analogues of quantum spins - in a 5-d non-Abelian Coulomb phase. As the fifth dimension is compactified\, quarks and gluons are confined inside h adrons and the theory dimensionally reduces to 4-d QCD. The 4-d gauge coup ling g2 = e2/β is controlled by the size β of the fifth dimension\, and the continuum and chiral limits are reached simultane-ously when β become s large in units of the 5-d gauge coupling e2. Similarly\, N = 1 supersymm etric Yang-Mills theory arises after orbifolding the extra dimension. If a similar non-perturbative mechanism cannot be found for supersymmetric the ories with light scalars\, the 'solution' of the gauge hierarchy problem m ay just be a perturbative illusion which cannot be realized without fine-t uning at a non-perturbative level. Natural mechanisms for dimensional redu ction also exist in lower dimensions. For example\, the 2-d CP(N-1) model with vacuum angle θ = 0 or π emerges from the dynamics of (2+1-d SU(N) q uantum spin ladders. In general\, D-theory provides a new perspective on t he non-perturbative dynamics of fields\, both from a numerical and from an analytical point of view.\n\nhttp://indico.cern.ch/conferenceDisplay.py?c onfId=a044822 LOCATION:CERN TH Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a044822 END:VEVENT BEGIN:VEVENT SUMMARY:Split supersymmetry DTSTART;VALUE=DATE-TIME:20041117T130000Z DTEND;VALUE=DATE-TIME:20041117T140000Z DTSTAMP;VALUE=DATE-TIME:20130524T202230Z UID:indico-event-a044983@cern.ch DESCRIPTION:The motivations and physical consequences of Split Supersymmet ry will be discussed.

In Split Supersymmetry\, the absence of new light scalars remove s the phenomenological difficulties of low-energy supersymmetry associated with flavour and CP violating effects. However\, the electric dipole mome nts of leptons and quarks do arise at two loops\, and are automatically at the level of present limits with no need for small phases\, making them a ccessible to several ongoing new-generation experiments.

Using both a duality-based and a field-theoretic def inition of the boundary of the per-turbative regime\, we re-evaluate the s ituation in a quantitative manner. We conclude that the simplest and most promising situations are those where some of the compactification radii ar e exceptionally large\, corresponding to highly anisotropic orbifold model s. Thus\, one is led to consider constructions which are known to the effe ctive field-theorist as higher-dimensional or orbifold grand unified theor ies (orbifold GUTs). In particular\, if the discrete symmetry used to brea k the GUT group acts freely\, a non-local breaking in the larger compact d imensions can be realized\, leading to a precise gauge coupling unificatio n as expected on the basis of the MSSM particle spectrum. Furthermore\, a somewhat more model dependent but nevertheless very promising scenario ari ses if the GUT breaking is restricted to certain singular points within th e manifold spanned by the larger compactification radii.\n\nhttp://indico. cern.ch/conferenceDisplay.py?confId=a051494 LOCATION:CERN TH Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a051494 END:VEVENT BEGIN:VEVENT SUMMARY:Spinor gravity DTSTART;VALUE=DATE-TIME:20050323T130000Z DTEND;VALUE=DATE-TIME:20050323T140000Z DTSTAMP;VALUE=DATE-TIME:20130524T202230Z UID:indico-event-a051781@cern.ch DESCRIPTION:A unified theory of gravity and gauge interactions can be base d on fundamental fermions. An action with diffeomorphism symmetry (general coordinate invariance) is formulated on the fermionic level without a met ric field. If preserved in the functional integral this symmetry implies t he emergence of a vielbein and graviton as composite states. We derive the gravitational field equations. The resulting effective theory may only ex hibit global and not local Lorentz-invariance. We show that this new geo-m etrical structure describes additional massless gravitational degrees of f reedom. Nevertheless\, it is compatible with all present tests - and we co nclude that the local character of the Lorentz-symmetry is actually not es tablished by observation. We further investigate the possibility that the difference between space and time (signature) results from spontaneous sym metry breaking. Finally we compare the prospects of such an approach with string theory.\n\nhttp://indico.cern.ch/conferenceDisplay.py?confId=a05178 1 LOCATION:CERN TH Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a051781 END:VEVENT BEGIN:VEVENT SUMMARY:Title to be announced DTSTART;VALUE=DATE-TIME:20050330T120000Z DTEND;VALUE=DATE-TIME:20050330T130000Z DTSTAMP;VALUE=DATE-TIME:20130524T202230Z UID:indico-event-a051782@cern.ch DESCRIPTION:http://indico.cern.ch/conferenceDisplay.py?confId=a051782 LOCATION:CERN TH Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a051782 END:VEVENT BEGIN:VEVENT SUMMARY:String theory as a holographic description of gauge theories DTSTART;VALUE=DATE-TIME:20050406T120000Z DTEND;VALUE=DATE-TIME:20050406T130000Z DTSTAMP;VALUE=DATE-TIME:20130524T202230Z UID:indico-event-a052025@cern.ch DESCRIPTION:According to the holographic hypothesis\, in a gravitational t heory the fundamental degrees of freedom filling a region of the space can be described by a lower dimensional theory living on the boundary of the region.

The former are summed by the BFKL equation\, the latter by conventional techni ques for event shapes\, but the two resummations have never been combined into a single calculation. I will review the existing calculations\, the r easons why their combination is problematic\, and recent progress towards a combination.

High energy effects are encoded in the local operators that live on a space-like brane used to describe the initial state of the unive rse (or the state of the universe through the bounce). This setup allows u s to formulate a naturalness problem for initial conditions\, much the sam e way as naturalness is defined in elementary particle physics. I use this language to constrain possible deviations of the initial state of inflati on from the standard Bunch-Davies vacuum.

This evolution has been driven by the tension between their classical and quantum properties. Both classical and quantum black h ole mechanics point to well-established thermodynamic properties\, like th e Hawking temperature\, and to a huge entropy that is proportional to the horizon area in Planck units. One of the problems is that a microscopic in terpretation of this entropy appears to be completely at odds with the cla ssical black-hole uniqueness theorems. In the late 1990's string theory pr ovided a very significant breakthrough in that it enabled one to describe individual microstates of a special class of black holes and identify the microstates in the proper numbers to account for the entropy. While remark able\, this calculation was done at weak coupling\, and so it does not giv e a clear picture of how these microstates would appear in something that an astronomer would recognize as a black hole. In the last few years there has been a proposal\, pioneered by Mathur\, and coming from string theory as to what the microstates look like at strong coupling and therefore in something that looks like a black hole. This proposal\, if correct\, repre sents a radical conceptual shift in how we should picture a black hole and its "interior." In this talk I will outline the microstate counting at we ak coupling in string theory and show how it naturally leads to Mathur's s trong coupling picture. I will also illustrate how this new view of black holes is very different from previous conceptions.\n\nhttp://indico.cern.c h/conferenceDisplay.py?confId=a061227 LOCATION:CERN TH Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a061227 END:VEVENT BEGIN:VEVENT SUMMARY:Emergent gravity DTSTART;VALUE=DATE-TIME:20060308T130000Z DTEND;VALUE=DATE-TIME:20060308T140000Z DTSTAMP;VALUE=DATE-TIME:20130524T202230Z UID:indico-event-a061233@cern.ch DESCRIPTION:http://indico.cern.ch/conferenceDisplay.py?confId=a061233 LOCATION:CERN TH Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a061233 END:VEVENT BEGIN:VEVENT SUMMARY:Dark matter lighting up the stars DTSTART;VALUE=DATE-TIME:20060315T130000Z DTEND;VALUE=DATE-TIME:20060315T140000Z DTSTAMP;VALUE=DATE-TIME:20130524T202230Z UID:indico-event-a061230@cern.ch DESCRIPTION:A sterile neutrino with a mass of several keV can account for cosmological dark matter\, can explain the observed velocities of pulsars\ , and can help reionize the universe by catalyzing the production of molec ular hydrogen and early star formation.

Examples of their multidisciplinary missions include the search for the particle nature of dark matter and for additional small dimensions of space. In the end\, their conceptual design is very much anchored to the o bservational fact that Nature produces protons and photons with energies i n excess of 1020 and 1013 electron volts\, respectively. The cosmic ray co nnection sets the scale of cosmic neutrino fluxes. The problem has been to develop a robust and affordable technology to build the kilometer-scale n eutrino detectors required to do the science. The AMANDA telescope using c lear deep Antarctic ice as a Cherenkov detector of muons and showers initi ated by neutrinos of all 3 flavours\, has met this challenge. We review th e results obtained with more than 5000 well-reconstructed neutrinos in the 50 GeV~500 TeV energy range collected during its first years of operation .

Axions could be copiousl y produced in the Sun. In magnetic fields they can oscillate to photons an d vice versa. The axion helioscope CAST uses an LHC magnet to convert sola r axions to X-rays. Also\, in the solar atmosphere the large scale magneti c fields reach occasionally several kGauss. Assuming the CAST working prin ciple occurring there much more efficiently\, it could explain the unexpec ted appearance of X-rays (from axions) or disappearance of light (into axi ons). Such processes can be behind persisting solar mysteries\, suggesting the participation of a) solar magnetic fields\, and b) radiatively decayi ng massive particles. Enigmatic behaviour leading to solar X-ray emission\ , coronal heating\, flares\, sunspots\, etc. is considered as evidence of overlooked signature of axions or other particles with similar properties.

Two examples of such dynamical tunneling processes are studied: creation of a soliton in the collision of highly energetic particles in a field-theory model\, and over-barrier reflection in quantum mechanics wit h two degrees of freedom. In the first example it is shown that in the lea ding semi-classical approximation the probability of collision-induced tun neling is saturated at some "optimal" energy and stays constant\, and expo nentially small at higher energies. The second example models the existenc e of optimal tunneling energy in the quantum mechanical framework. It allo ws to check the validity of the semi-classical methods in the regime of dy namical tunneling by the comparison of their results with exact numerical quantum computations.

For most of this time even the ex istence of solar-climate variability has been controversial - perhaps beca use the observations have largely involved correlations between climate an d the sunspot cycle. However\, more recent palaeoclimatic data\, largely b ased on isotopic measurements of climate and cosmic ray variability\, prov ide substantial evidence for solar forcing of the climate. Although the un derlying mechanism remains a mystery\, satellite data suggest that clouds may be influenced by galactic cosmic rays\, which are modulated by the sol ar wind and\, on longer time scales\, by the geomagnetic field and the gal actic environment of Earth.

In particula r\, baryon acoustic oscillations (BAO) have recently emerged as one of the \nmost powerful techniques to characterize the equation of state of dark energy and its possible evolution. \n In the next years\, several large sc ale projects will attempt to use BAO to characterize dark energy by \nmeas uring redshifts for hundreds of thousands of galaxies.

Thus with an optimistic hope a bound state of 6 top + 6 anti top\n quarks could exist and have a mass much smaller than the mass of 12 top qu arks. If so there could exist a phase - another vacuum - essentially degen erate with the one we live in but having a condensate of the\nsuggested bo und states. Postulating such extra degenerate phases is what we have long\ nspeculated as generalization of giving up solving the cosmological\nconst ant problem: we use the need for assuming the cosmological constant small anyway to suggest that we instead assume there to be many vacua all\nhavi ng small cosmological constants. This we called multiple point\nprinciple. Imposing this principle to give degenerate bound state condensate with th e usual vacuum leads at first to a top-Yukawa coupling\nbeing g_t = 1.34\, but with a bit of corrections involving the left b-quark\nit gets down to wards the experimental value 0.95.\n\nThe main point of the talk is that t his boundstate can - with very mild\nspeculative hope - be produced in LHC or perhaps even Tevatron\nby first producing a pair of a related boundsta te consisting of\nsay 6 top and 5 anti top with a crossection similar to t hat of producing\nfourth generation\, if such one had existed. Because of the 6top plus 6 anti top bound state\nbeing stronger bound - because of mo re binding combinations - the\n6top + 5 anti-top state is supposed to deac ay to the one with 6 top + 6 anti top under the emission of a virtual or r eal top-quark. Since the\n6 top + 6 anti-top state is expected to decay it self hadronicly to\nroughly 12 gluon jets and thus with high multiplicity\ , it is expected\nthat the events with our bound states produced this way would show\nup as top-quark pair events with abnormously high multiplicity !\nIt may require special preparation to be sure to tricker on these\neven ts in the case that the top-quarks acompanying our bound states\nare only virtual.\n\nThe model here presented is mainly motivated as a way of uniti ng the\nproblem of why the weak scale is so low compared to the fundamenta l\nor say Planck scale with the cosmological constant problem\, which as\n mentioned is not solved but just fine tuned (in the present presentation). \n\nhttp://indico.cern.ch/conferenceDisplay.py?confId=25672 LOCATION:CERN TH Theory Conference Room URL:http://indico.cern.ch/conferenceDisplay.py?confId=25672 END:VEVENT BEGIN:VEVENT SUMMARY:Topological Strings confront Reality\,\nTadpole Cancellation\, and Background Independence DTSTART;VALUE=DATE-TIME:20080130T130000Z DTEND;VALUE=DATE-TIME:20080130T143000Z DTSTAMP;VALUE=DATE-TIME:20130524T202230Z UID:indico-event-27036@cern.ch DESCRIPTION:I review recent progress in topological string theory and how it\nis\, or might be\, connected to other problems of current interest in string\ntheory.\n\nhttp://indico.cern.ch/conferenceDisplay.py?confId=27036 LOCATION:CERN TH Theory Conference Room URL:http://indico.cern.ch/conferenceDisplay.py?confId=27036 END:VEVENT BEGIN:VEVENT SUMMARY:On the possible links between Electroweak Symmetry Breaking and Da rk Matter DTSTART;VALUE=DATE-TIME:20080206T130000Z DTEND;VALUE=DATE-TIME:20080206T140000Z DTSTAMP;VALUE=DATE-TIME:20130524T202230Z UID:indico-event-25441@cern.ch DESCRIPTION:The Weakly Interacting Massive Particle scenario of Dark Matte r\, which is the most straightforward scenario for explaining dark matter in the Universe\, requires that the Dark Matter particle mass lies in a ra nge astonishingly close to the electroweak scale. This suggests that there might be a close relation between these two scales. Furthermore this lead s to the question: could the presence of the Dark Matter particle around t he electroweak scale\, play an important role in the origin of Electroweak Symmetry Breaking? \n\nAfter looking at how close are these two scales\, four mechanisms where Dark Matter and Electroweak Symmetry Breaking are r elated at various levels will be considered: i) first the usual neutralino susy dark matter scenario will be briefly considered along this perspecti ve. ii) second in a version of the inert two Higgs doublet model it will b e shown that DM can change importantly the electroweak precision measureme nt expectations for the Higgs boson mass. iii) third it will be shown how\ , in various models\, the DM mass can be proportional to the electroweak s cale\, providing an explanation for the similarity of both scales. iv) fou rth\, based on the assumption of scale invariance\, another version of the inert Higgs model will be considered where\, in addition of having both s cales proportional to each other\, the presence of dark matter is at the o rigin of electroweak symmetry breaking.

This\nfactorisation was speculated in general Regge theory and\nla ter proved for QCD.

We show that by\nfurther constraining the analyticity of scattering\n amplitudes away from the exact limits\, we get good agreement\norder by or der with full\, fixed order perturbation theory\,\nand therefore get firm predictions on the all-order\nbehaviour. As an example\, we study Higgs bo son production\nthrough gluon fusion in association with at least two jets \nat the LHC.

A new oscillation phenomenon providing information about neutrino mixing is obtained by fol lowing the ion before and during the decay. This normally neglected proce ss is shown to be consistent with quantum mechanics and causality. Measuri ng the oscillation without detecting the neutrino avoids losses in convent ional experiments due to the low neutrino absorption cross section. The no rmally unobservable long wave lengths are made observable by having the ra dioactive source move a long distance circulating around in a storage ring . The initial ion wave packet has a momentum spread required by Heisenber g and contains pairs of components with different momenta and energies. Th ese can produce neutrino amplitudes in two mass eigenstates with different momenta which mix to produce a single $\\nu_e$ state. In this typical qu antum mechanics ``two-slit" or ``which path" experiment a transition betw een the same initial and final states can go via two paths in energy-momen tum space with a phase difference producing interference and oscillations. \n\nhttp://indico.cern.ch/conferenceDisplay.py?confId=32006 LOCATION:CERN TH Theory Conference Room URL:http://indico.cern.ch/conferenceDisplay.py?confId=32006 END:VEVENT BEGIN:VEVENT SUMMARY:Dark matter burning stars at the Galactic centre DTSTART;VALUE=DATE-TIME:20080702T120000Z DTEND;VALUE=DATE-TIME:20080702T130000Z DTSTAMP;VALUE=DATE-TIME:20130524T202230Z UID:indico-event-34081@cern.ch DESCRIPTION:It is possible that stars close to the very centre of our gala xy can behave differently due to the capture and subsequent annihilation of dark matter.

After a brief review of wh at\nis technically feasible today\, it is shown that the breaking of the\n symmetry goes along with a condensation of the low quark modes as\npredict ed in 1980 by Banks and Casher. The mode condensation is a\nprominent effe ct that provides the perhaps most direct and robust\ntheoretical evidence for the symmetry-breaking pattern presumed by\nchiral perturbation theory. In particular\, the chiral condensate can\nbe computed straightforwardly by counting the low modes and the\nBanks-Casher relation also sheds some l ight onto what the dynamical\nreasons for the spontaneous breaking of the symmetry might be.\n\nhttp://indico.cern.ch/conferenceDisplay.py?confId=44 310 LOCATION:CERN TH Theory Conference Room URL:http://indico.cern.ch/conferenceDisplay.py?confId=44310 END:VEVENT BEGIN:VEVENT SUMMARY:Complexity and statistical mechanics DTSTART;VALUE=DATE-TIME:20081112T130000Z DTEND;VALUE=DATE-TIME:20081112T143000Z DTSTAMP;VALUE=DATE-TIME:20130524T202230Z UID:indico-event-30910@cern.ch DESCRIPTION:In this talk I will firstly briefly review some of the problem s that we face when we study complex systems.

Over that time\, we have gained reliable insight in to the thermodynamics of quark-gluon plasma at accessible temperatures fro m lattice QCD calculations\, and we have understood much about its dynamic s in the high temperature limit where it becomes weakly coupled. However\, in the last five years experimental discoveries at the Relativistic Heavy Ion Collider have taught us that\, at least at temperatures within a fact or of two of that at which hadrons ionize\, the dynamics of quark-gluon pl asma is closer to the ideal liquid limit than to the ideal gas limit. Thes e experimental data demand a theoretical understanding of the dynamics of strongly coupled quark-gluon plasma. Such calculations in QCD itself are i n their infancy\, but string theory provides us with robust tools for exac tly this purpose\, applicable to the quark-gluon plasmas of many QCD-like theories. I will describe some of the many new insights into the propertie s of strongly coupled plasma obtained recently from these AdS/CFT calculat ions\, and look ahead toward the expected interplay between these calculat ions and heavy ion collision experiments at the LHC.\n\nhttp://indico.cern .ch/conferenceDisplay.py?confId=34788 LOCATION:CERN TH Theory Conference Room URL:http://indico.cern.ch/conferenceDisplay.py?confId=34788 END:VEVENT BEGIN:VEVENT SUMMARY:Matching NLO Calculations with Parton Shower: POWHEG DTSTART;VALUE=DATE-TIME:20081126T130000Z DTEND;VALUE=DATE-TIME:20081126T140000Z DTSTAMP;VALUE=DATE-TIME:20130524T202230Z UID:indico-event-43119@cern.ch DESCRIPTION:I will give a brief introduction to Monte Carlo Parton Shower and illustrate a new method\, called POWHEG\, to merge the benefits of Par ton Shower and next-to-leading order calculations.

In particular\,\nthe resulting Kubo formulae allow to determine the hydrodyn amic\ntransport coefficients in field theories both at weak coupling\n(via kinetic theory) and strong coupling (via the gauge/string duality).\nThe fluid dynamic equations are readily solved on a computer\,\ne.g. to descri be bulk properties of nuclear collisions at the LHC.\n\nhttp://indico.cern .ch/conferenceDisplay.py?confId=39613 LOCATION:CERN TH Theory Conference Room URL:http://indico.cern.ch/conferenceDisplay.py?confId=39613 END:VEVENT BEGIN:VEVENT SUMMARY:Gaugino Mediation of Supersymmetry Breaking DTSTART;VALUE=DATE-TIME:20081210T130000Z DTEND;VALUE=DATE-TIME:20081210T140000Z DTSTAMP;VALUE=DATE-TIME:20130524T202230Z UID:indico-event-40908@cern.ch DESCRIPTION:Gaugino mediation naturally solves the supersymmetric flavor p roblem.

Colla psed\, virialized dark matter haloes condense out of these initial fluctua tions. This process can be studied by N-body simulations\, but it is impor tant to be able to understand the results of such simulations in simpler t erms. We present an analytical computation of the dark matter halo mass fu nction based on the the excursion set method\, where the problem is mapped into the so-called first-passage time problem of a random walk in the pr esence of a barrier.

Conversely the presence of such a plenitude of axions (an "a xiverse") would be evidence for string theory\, since it arises due to the topological complexity of the extra-dimensional manifold and is ad hoc in a theory with just the four familiar dimensions. We investigate how upcom ing astrophysical experiments will explore the existence of such axions ov er a vast mass range from 10^-33eV to 10^-10eV. Axions with masses between 10^-33eV to 10^-28eV cause a rotation of the CMB polarization that is con stant throughout the sky. The predicted rotation angle is of order \\alpha ~1/137. Axions in the mass range 10^-28eV to 10^-18eV give rise to multipl e steps in the matter power spectrum\, that will be probed by upcoming gal axy surveys and 21 cm tomography. Axions in the mass range 10^-22eV to 10^ -10eV affect the dynamics and gravitational wave emission of rapidly rotat ing astrophysical black holes through the Penrose superradiance process. W hen the axion Compton wavelength is of order of the black hole size\, the axions develop "superradiant" atomic bound states around the black hole "n ucleus". Their occupation number grows exponentially by extracting rotatio nal energy from the ergosphere\, culminating in a rotating Bose-Einstein a xion condensate emitting gravitational waves. This mechanism creates mass gaps in the spectrum of rapidly rotating black holes that diagnose the pre sence of axions. The rapidly rotating black hole in the X-ray binary LMC X -1 implies an upper limit on the decay constant of the QCD axion f_a\n\nht tp://indico.cern.ch/conferenceDisplay.py?confId=62290 LOCATION:CERN TH Theory Conference Room URL:http://indico.cern.ch/conferenceDisplay.py?confId=62290 END:VEVENT BEGIN:VEVENT SUMMARY: Ultra-high energy cosmic rays and the Pierre Auger Observatory DTSTART;VALUE=DATE-TIME:20090715T120000Z DTEND;VALUE=DATE-TIME:20090715T130000Z DTSTAMP;VALUE=DATE-TIME:20130524T202230Z UID:indico-event-61366@cern.ch DESCRIPTION:The different issues related to ultra-high energy cosmic ray p hysics and astrophysics that are being addressed by the Pierre Auger Obser vatory will be reviewed\, discussing in particular the latest results on t he spectrum\, the ankle and the GZK suppression\, the bounds on neutrinos and photons and the observations of anisotropies in the arrival directions .\n\nhttp://indico.cern.ch/conferenceDisplay.py?confId=61366 LOCATION:CERN TH Theory Conference Room URL:http://indico.cern.ch/conferenceDisplay.py?confId=61366 END:VEVENT BEGIN:VEVENT SUMMARY:Harmony in scattering amplitudes: from QCD to gravity DTSTART;VALUE=DATE-TIME:20090722T120000Z DTEND;VALUE=DATE-TIME:20090722T133000Z DTSTAMP;VALUE=DATE-TIME:20130524T202230Z UID:indico-event-58213@cern.ch DESCRIPTION:Scattering amplitudes have a remarkable simplicity and harmony \, exposed using modern on-shell methods.

This Lagr angian is written using standard superspace and the superfields are constr ained to include only the light degrees of freedom. The Goldstino resides in a (constrained) chiral superfield X which is naturally identified at s hort distances. This allows us to exactly compute the IR behavior of some correlation functions even in strongly coupled theories with SUSY breaking . The Goldstino couplings above the scale of the matter superpartners are determined by identifying X with the standard spurion. At energies below the superpartners' scale\, fermions\, scalars (including Goldstone bosons ) and gauge fields are also described by constrained superfields. Our fra mework makes it easy to find the leading order terms in the Lagrangian and to control their corrections. It simplifies the derivation of many known results and leads to new ones.\n\nhttp://indico.cern.ch/conferenceDisplay .py?confId=64863 LOCATION:CERN TH Theory Conference Room URL:http://indico.cern.ch/conferenceDisplay.py?confId=64863 END:VEVENT BEGIN:VEVENT SUMMARY:RESERVED FOR THE PARTICLE COSMOLOGY WORKSHOP DTSTART;VALUE=DATE-TIME:20090916T120000Z DTEND;VALUE=DATE-TIME:20090916T130000Z DTSTAMP;VALUE=DATE-TIME:20130524T202230Z UID:indico-event-60395@cern.ch DESCRIPTION:http://indico.cern.ch/conferenceDisplay.py?confId=60395 LOCATION:CERN TH common room URL:http://indico.cern.ch/conferenceDisplay.py?confId=60395 END:VEVENT BEGIN:VEVENT SUMMARY:Heavy quarks at high temperature: can we understand thermalization from first principles?

In an E ffective Field Theory (EFT) approach an argument parallel to that in QCD a nd the chiral anomaly shows that the trace anomaly must play a special ro le in the EFT of low energy gravity. Indeed the conformal anomaly implies the existence of new long range massless scalar degrees of freedom in grav ity\, not present in the classical Einstein theory\, which couple to class ical sources\, contribute to gravitational scattering processes and have long range gravitational effects. These novel macroscopic effects are sig nificant in the vicinity of black hole event horizons. The fluctuations of the anomaly scalars also imply that the cosmological term is not a const ant but a kind of gravitational condensate which is state dependent and r uns to zero in the infrared. These considerations suggest a completely non -singular quantum final state of gravitational collapse in which the clas sical black hole event horizon is replaced by a thin shell\, and its inter ior is replaced by a vacuum condensate with dark energy equation of the st ate\, p= - rho. Gravitational condensate stars have a modest entropy and d o not suffer an information paradox.

This requirement is quantified by a fine tuning measure\, useful in correlating the impact of the various experimental measurements relevant to the search for supersymmetry and al so in identifying the most sensitive measurements for testing SUSY.\nA cal culation of fine tuning to two-loop order in the CMSSM allows us to determ ine the present limits on the CMSSM parameter space and identify the measu rements at the LHC that are most significant in covering the remaining spa ce consistent with a given level of fine tuning. Without imposing the LEP Higgs mass bound\, the most likely mass\, consistent with the dark matter abundance and the non-observation of SUSY states to date\, is found to be just above the current limit. Dark matter searches provide a sensitive pro be of the lowest fine-tuned points. The extension of SUSY tests to cover the full MSSM parameter space is discussed. For the case of non-universal gaugino masses a second focus point is identified that reduces fine-tunin g.

I also discuss the problem of the radiation by accelerated sources in the vacuum. I argue that the corresponding space-time distribution is not correctly predicted by the supergravity approximation (the semiclassical limit of the dual st ring theory).

However\, these insulators are characterized by a topological order which implies the existence of robust edges states. In the case of the Quantum Hall Effect\, these edge states are chiral mode s\, reflecting the breaking of time reversal symmetry.

The second is the recent\ncosmological acceleration\, driven by either an unnaturally small cosmological constant or by an unknown "Dark Energy" . Scalar fields are extensively used to model cosmological dynamics during both these époques. However\, it turns out that the main observational results can be written in terms of hydrodynamical quantities like pressur e\, energy density\, and the speed of sound.

For some purposes\, such as the esti mation of detector corrections\, this is fine. But for the coming era of searches for discrepancies with the Standard Model\, the best possible pre cision will be\nneeded.

However\, better fits are ob tained by non-standard scenarios that better reproduce the anomalies in pr esent data.

I will give an overview of these processes\, both the present e xperimental status as well as standard model and new physics interpretatio ns. For instance\, there are tight constraints on NP models that could exp lain A_FB. Many NP models that were on the market before the first top res ults from the LHC are now in tension with the charge asymmetry measurement s at the LHC. For general enough new physics models the correlation betwee n the two observables is lost\, however. On the other hand\, there is some support for the SM origin of Delta A_CP. Reasonable NP models can also ex plain Delta A_CP and one can distinguish between the two of them experimen tally using just charm decay data.

Despite its simplicity\, the theory exhibits many of the salient features expected from more mature quantum gravity models\, inclu ding the absence of local off-shell observables\, a minimal length\, a ma ximum achievable (Hagedorn) temperature\, as well as (integrable relatives of) black holes. We argue that considered as a UV complete relativistic 2 -dimensional quantum field theory the model exhibits a new type of renorma lization group flow behavior\, ``asymptotic fragility".\n\nhttp://indico.c ern.ch/conferenceDisplay.py?confId=200597 LOCATION:CERN TH Conference Room URL:http://indico.cern.ch/conferenceDisplay.py?confId=200597 END:VEVENT BEGIN:VEVENT SUMMARY:To split or not to split DTSTART;VALUE=DATE-TIME:20120822T120000Z DTEND;VALUE=DATE-TIME:20120822T130000Z DTSTAMP;VALUE=DATE-TIME:20130524T202230Z UID:indico-event-200471@cern.ch DESCRIPTION:http://indico.cern.ch/conferenceDisplay.py?confId=200471 LOCATION:CERN TH Conference Room URL:http://indico.cern.ch/conferenceDisplay.py?confId=200471 END:VEVENT BEGIN:VEVENT SUMMARY:The mass of the Higgs boson\, the great desert\, and asymptotic sa fety of gravity DTSTART;VALUE=DATE-TIME:20120829T120000Z DTEND;VALUE=DATE-TIME:20120829T130000Z DTSTAMP;VALUE=DATE-TIME:20130524T202230Z UID:indico-event-198224@cern.ch DESCRIPTION:Based on a scenario for asymptotic safety for gravity the Higg s boson mass was predicted in 2009 to be 126 GeV\, with a few GeV uncertai nty. We review this proposal and its implications for a desert between the Fermi- and Planck- scales\, the possible solutions to the gauge hierarchy problem and the unification of all interactions.\n\nAn observed mass of t he Higgs boson close to 126 GeV suggests a solution of the hierarchy probl em at a unification scale close to the Planck mass. It also points to the possibility that the physics beyond the standard model needed for dark ene rgy\, dark matter\, baryon asymmetry\, neutrino masses and inflation may b e characterized by very high energy scales or extremely small couplings\, and not be accessible to laboratory experiments.\n\nA crucial ingredient f or the robustness of the prediction of the Higgs boson mass is the existen ce of a partial infrared fixed point for the ratio between squared Yukawa coupling of the top quark and quartic scalar coupling\, and the properties of the associated infrared interval.\n\nhttp://indico.cern.ch/conferenceD isplay.py?confId=198224 LOCATION:CERN TH Conference Room URL:http://indico.cern.ch/conferenceDisplay.py?confId=198224 END:VEVENT BEGIN:VEVENT SUMMARY:The Hottest\, and Most Liquid\, Liquid in the Universe DTSTART;VALUE=DATE-TIME:20120919T120000Z DTEND;VALUE=DATE-TIME:20120919T130000Z DTSTAMP;VALUE=DATE-TIME:20130524T202230Z UID:indico-event-195300@cern.ch DESCRIPTION:Before experiments at the Relativistic Heavy Ion Collider star ted recreating little droplets of the matter that filled the microseconds- old universe\, this stuff was thought to be a tenuous gas-like plasma. Now we know from experiments at RHIC and at the Large Hadron Collider that at these extreme temperatures nature serves up hot quark soup --- the hottes t liquid in the universe and the liquid that flows with the least dissipat ion. The only other comparably liquid liquid is the coldest liquid in the universe\, namely the fluid made of trapped fermionic atoms at microKelvin rather than TeraKelvin temperatures. These are two examples of strongly c oupled fluids without any apparent quasiparticle description. I will descr ibe how physicists are using RHIC and LHC experiments --- as well as calcu lations done using dualities between liquids and black holes discovered in string theory --- to discern the properties of hot quark soup. In this do main\, string theory is answering questions posed by laboratory experiment s. I will describe the opportunities and challenges for coming experiments at RHIC and the LHC\, among them understanding how a liquid with no appar ent particulate description emerges from quarks and gluons\, searching for a critical point in the QCD phase diagram and\, maybe\, taking snapshots of QCD sphalerons.\n\nhttp://indico.cern.ch/conferenceDisplay.py?confId=19 5300 LOCATION:CERN TH Conference Room URL:http://indico.cern.ch/conferenceDisplay.py?confId=195300 END:VEVENT BEGIN:VEVENT SUMMARY: Investigating sign problems in QCD at nonzero baryon number DTSTART;VALUE=DATE-TIME:20120926T120000Z DTEND;VALUE=DATE-TIME:20120926T130000Z DTSTAMP;VALUE=DATE-TIME:20130524T202230Z UID:indico-event-196441@cern.ch DESCRIPTION:Simulations of QCD at nonzero baryon number are associated wit h severe sign problems and noise\, so far an insurmountable obstacle to co nnecting QCD to the properties of ordinary matter.

Weakly Interacting Massive Particles\, which may be the ir own antipartners\, collect inside the first stars and annihilate to pro duce a heat source that can power the stars. A new stellar phase results\, a Dark Star\, powered by dark matter annihilation as long as there is dar k matter fuel\, with lifetimes from millions to billions of years. Dark st ars are very bright diffuse puffy objects during the DS phase\, and grow t o be very massive. In fact\, we have found they can to grow to 10^5-10^7 s olar masses with luminosities 10^9-10^11 solar luminosities. Such objects will be observable with James Webb Space Telescope (the sequel to HST).

In this context\ , the effective field theory paradigm represents the ideal setup to explor e and systematically study the signatures that come from interactions\, an d additionally to directly map what we are learning from data into theory. I will describe two recent applications of this paradigm to Cosmology: th e Effective Field Theory of Inflation and the Effective Field Theory of Co smological Large Scale Structures. The first example represents the genera l parametrization of adiabatic fluctuations around an inflationary solutio ns\, and it allows us to study the non-Gaussian signatures of Inflation\, that I will describe. The second example is in the context of the gravitat ional clustering of dark matter. In our universe matter perturbations are large on short distances and small on large distances: strongly coupled in the UV and weakly coupled in the IR. We formulate an effective descriptio n based on an IR effective fluid that allows us to formulate a manifestly convergent perturbative expansion to describe weak dark matter clustering. This is expected to be important to understand observations from next gen eration cosmological surveys.\n\nhttp://indico.cern.ch/conferenceDisplay.p y?confId=214085 LOCATION:CERN TH Conference Room URL:http://indico.cern.ch/conferenceDisplay.py?confId=214085 END:VEVENT BEGIN:VEVENT SUMMARY:Recent results on B and B_s meson properties from Heavy Quark Effe ctive Theory DTSTART;VALUE=DATE-TIME:20130123T130000Z DTEND;VALUE=DATE-TIME:20130123T140000Z DTSTAMP;VALUE=DATE-TIME:20130524T202230Z UID:indico-event-215978@cern.ch DESCRIPTION:The masses\, decay constants\, and decay form-factors of B and B_s mesons are important ingredients in the search for Beyond-the-Standar d-Model physics in the heavy flavor sector.
