We show how the varyin g longitudinal extent of the sources generates correlations in the initial entropy deposition\, which later contribute to the observed correlations in hadron production. Our analytic analysis allows to understand their str ucture and to identify the component due to the underlying fluctuation of the number of sources and the component from the genuine longitudinal fluc tuations. Our results reproduce semiquantitatively the basic features of t he recent measurements at the LHC.\n\nhttps://indico.cern.ch/event/469857/ contributions/2143147/ LOCATION:Centro de Congressos\, Instituto Superior Técnico\, Alameda Camp us Room 02.2 URL:https://indico.cern.ch/event/469857/contributions/2143147/ END:VEVENT BEGIN:VEVENT SUMMARY:Colored particle-in-cell simulations for heavy-ion collisions DTSTART;VALUE=DATE-TIME:20160525T161000Z DTEND;VALUE=DATE-TIME:20160525T163000Z DTSTAMP;VALUE=DATE-TIME:20190325T174624Z UID:indico-contribution-192514-2143779@indico.cern.ch DESCRIPTION:Speakers: David Mueller (Vienna University of Technology)\nWe present our work on the simulation of the quark-gluon-plasma using the col ored particle-in-cell (CPIC) method. CPIC is a generalization of particle- in-cell simulations - commonly used in plasma physics - to real-time non-a belian lattice gauge theories. Using this method we are able to model the early time dynamics of heavy-ion collisions in the laboratory frame in 3+1 dimensions. In particular we study the effects of finite pancake thicknes s in the McLerran-Venugopalan model. Our approach requires a consistent tr eatment of gauge fields and color currents\, which is achieved using charg e-conserving CPIC methods. We show that the description in the laboratory frame agrees with boost-invariant approaches as a limiting case and invest igate collisions beyond boost-invariance.\n\nhttps://indico.cern.ch/event/ 469857/contributions/2143779/ LOCATION:Centro de Congressos\, Instituto Superior Técnico\, Alameda Camp us Room 02.2 URL:https://indico.cern.ch/event/469857/contributions/2143779/ END:VEVENT BEGIN:VEVENT SUMMARY:Determination of QGP initial conditions and medium properties via a Bayesian model to data analysis DTSTART;VALUE=DATE-TIME:20160525T153000Z DTEND;VALUE=DATE-TIME:20160525T155000Z DTSTAMP;VALUE=DATE-TIME:20190325T174624Z UID:indico-contribution-192514-2143117@indico.cern.ch DESCRIPTION:Speakers: Scott Moreland (Duke University)\nInitial state mode ls translate the spacetime overlap of nuclear density between projectile a nd target nuclei to generate profiles of entropy (or energy) at the QGP th ermalization time which are subsequently evolved by relativistic viscous f luid dynamics. Historically\, these initial conditions were generated by o ne of two means: either from a two-component Glauber ansatz which asserts an admixture of soft and hard collision processes or from specific calcula tions in Color-Glass Condensate (CGC) effective field theory.\n\nIn contra st to the phenomenological approach of the two-component Glauber model whe re the binary collision fraction is tuned to fit experiment\, CGC initial conditions represent predictions calculated from an underlying effective f ield theory. While modern CGC initial condition models have been highly ef fective in describing the wealth of bulk observables at RHIC and the LHC\, multiple models exist in the literature which predict different results a nd describe the data with varying degrees of success.\n\nIn this talk\, we use a parametric initial condition ansatz which mimics the behavior of CG C calculations and extends the coverage of existing two-component parametr ic mappings to span the full space of reasonable initial condition models. We show that the parameterized initial conditions are highly constrained by bulk observables utilizing Bayesian statistics and a multi-parameter m odel to data comparison that relies on a state-of-the-art hybrid model for calculating the time-evolution of the QGP phase and its subsequent decay into the hadronic final state. We compare these results to specific calcul ations in CGC effective field theory and discuss implications for the init ial stages of QGP formation.\n\nhttps://indico.cern.ch/event/469857/contri butions/2143117/ LOCATION:Centro de Congressos\, Instituto Superior Técnico\, Alameda Camp us Room 02.1 URL:https://indico.cern.ch/event/469857/contributions/2143117/ END:VEVENT BEGIN:VEVENT SUMMARY:Mapping initial state correlations in rapidity unsing collective f low DTSTART;VALUE=DATE-TIME:20160524T172000Z DTEND;VALUE=DATE-TIME:20160524T174000Z DTSTAMP;VALUE=DATE-TIME:20190325T174624Z UID:indico-contribution-192514-2143148@indico.cern.ch DESCRIPTION:Speakers: Piotr Bozek (AGH University of Science and Technolog y)\nWe present results of a 3+1 dimensional hydrodynamic model for flow co rrelations in pseudorapidity.

The main purpose of ALICE is to investigate t he properties of the deconfined state of nuclear matter\, the Quark-Gluon Plasma (QGP). Quarkonium measurements play a crucial role in this investig ation. Indeed\, heavy quarks are created during the initial stages of the collision\, before the QGP formation\, and their number is conserved throu ghout the partonic and hadronic phases of the collision. The sequential su ppression of the quarkonium states by colour screening has long been sugge sted as a signature and thermometer of the QGP. However\, the first result s on quarkonium suppression in Pb-Pb collisions at the LHC seem to indicat e that for charmonia both regeneration and colour screening mechanisms pla y a role\, while for bottomonia the regeneration mechanism should be small . Additionally\, ALICE has recently reported an excess of J/$\\psi$ at ver y low transverse momentum (below 300 MeV/$c$)\, presumably of electromagne tic origin that could become a valuable probe of the system.\n\nWe will pr esent the latest results on quarkonium production in Pb-Pb collisions at L HC energies measured by ALICE. Quarkonia are measured at mid-rapidity in t he dielectron decay channel and at forward rapidity in the dimuon one. Com parisons of measurements at different collision energies and to available theoretical calculations will be discussed.\n\nhttps://indico.cern.ch/even t/469857/contributions/2143783/ LOCATION:Centro de Congressos\, Instituto Superior Técnico\, Alameda Camp us Room 02.1 URL:https://indico.cern.ch/event/469857/contributions/2143783/ END:VEVENT BEGIN:VEVENT SUMMARY:Latest jet results in pp\, pPb and PbPb collisions from CMS DTSTART;VALUE=DATE-TIME:20160524T145000Z DTEND;VALUE=DATE-TIME:20160524T151000Z DTSTAMP;VALUE=DATE-TIME:20190325T174624Z UID:indico-contribution-192514-2143115@indico.cern.ch DESCRIPTION:Speakers: Kaya Tatar (Massachusetts Inst. of Technology (US))\ nThis talk summarizes the latest results on jets in pp\, pPb and PbPb coll isions from the CMS collaboration\n\nhttps://indico.cern.ch/event/469857/c ontributions/2143115/ LOCATION:Centro de Congressos\, Instituto Superior Técnico\, Alameda Camp us Room 02.1 URL:https://indico.cern.ch/event/469857/contributions/2143115/ END:VEVENT BEGIN:VEVENT SUMMARY:Azimuthal anisotropies for low- and high-pT particles in PbPb and pPb collisions with CMS DTSTART;VALUE=DATE-TIME:20160525T140000Z DTEND;VALUE=DATE-TIME:20160525T142000Z DTSTAMP;VALUE=DATE-TIME:20190325T174624Z UID:indico-contribution-192514-2143787@indico.cern.ch DESCRIPTION:Speakers: Quan Wang (University of Kansas (US))\nPrevious meas urements have demonstrated the collective nature of multiparticle correlat ions in high-multiplicity pPb collisions at the LHC. This collectivity\, w hile consistent with a hydrodynamic flow origin\, can also be interpreted in terms of initial state effects arising from gluon saturation. To invest igate the detailed properties of this collectivity\, differential Fourier coefficients in transverse momentum and pseudorapidity are presented based on a variety of analysis methods using data obtained with the CMS detecto r at the LHC. The multiparticle nature of the correlations is explored usi ng 4-\, 6- and 8-particle cumulant analyses as well as a Lee-Yang Zeros an alysis that accounts for correlations among all particles. An event-plane analysis using the scalar product method is performed where the influence of recently demonstrated event-plane decorrelation on the pseudorapidity d ependence is considered. The pPb collision results are compared to periphe ral PbPb collision results obtained with comparable mid-rapidity charged p article densities. While a significant pseudorapidity dependence is observ ed in the azimuthal dependence of the particle yields\, a decorrelation of the event-plane angle with pseudorapidity can account for much of the obs erved behavior.\n\nhttps://indico.cern.ch/event/469857/contributions/21437 87/ LOCATION:Centro de Congressos\, Instituto Superior Técnico\, Alameda Camp us Room 02.1 URL:https://indico.cern.ch/event/469857/contributions/2143787/ END:VEVENT BEGIN:VEVENT SUMMARY:Multiplicity dependence of strange particle production in pp colli sions with the ALICE detector DTSTART;VALUE=DATE-TIME:20160524T174000Z DTEND;VALUE=DATE-TIME:20160524T180000Z DTSTAMP;VALUE=DATE-TIME:20190325T174624Z UID:indico-contribution-192514-2143067@indico.cern.ch DESCRIPTION:Speakers: Fiorella Fionda (Universita e INFN (IT))\nRecent mea surements in high-multiplicity proton-proton (pp) and proton-lead (p-Pb)\n collisions show several features that are similar to those observed in hea vy-ion collisions. In this respect strangeness production may provide a va luable investigative\ntool.\n\nBaryon-to-meson ratios\, such as Λ/KS0\, h ave been measured\ndifferentially in *p*T and show an evolution with incre asing charged particle\nmultiplicity in small systems similar to the one o bserved with centrality in heavy-ion\ncollisions\, where this behaviour is interpreted to be strongly related to the\nhydrodynamical evolution of th e system.

As an example the correlation between mean-event transverse momenta of charged particles in separated rapidity intervals is considered. The calc ulations are fulfilled in the model with string fusion by introducing a la ttice in transverse plane. The dependence of the correlation strength on t he collision centrality is obtained for different initial energies. It is shown that above RHIC energy the dependence reveals the decline of the cor relation coefficient for most central collisions\, reflecting the attenuat ion of color field fluctuations due to the string fusion at large string d ensity. It is also found that contrary to the correlation between transver se momenta of single particles the strength of the correlation between mea n-event transverse momenta of particles in two separated rapidity interval s is not decreasing with the total number of produced strings\, remaining significant even in the case of Pb-Pb collisions\, in which the total numb er of strings can reach several thousand. All this makes this type of corr elation promising for the observation of the signatures of string fusion a t the initial stage of hadronic interaction in relativistic heavy ion coll isions at LНС energy.\n\nThe work was supported by the RFBR grant 15-02- 02097 and the Saint-Petersburg State University grant 11.38.197.2014.\n\nh ttps://indico.cern.ch/event/469857/contributions/2143134/ LOCATION:Centro de Congressos\, Instituto Superior Técnico\, Alameda Camp us Room 02.2 URL:https://indico.cern.ch/event/469857/contributions/2143134/ END:VEVENT BEGIN:VEVENT SUMMARY:Femtoscopy with identified charged pions in proton-lead collisions at $\\sqrt{s_{\\mathrm{NN}}}=5.02~\\mathrm{TeV}$ with the ATLAS detector DTSTART;VALUE=DATE-TIME:20160524T164000Z DTEND;VALUE=DATE-TIME:20160524T170000Z DTSTAMP;VALUE=DATE-TIME:20190325T174624Z UID:indico-contribution-192514-2143125@indico.cern.ch DESCRIPTION:Speakers: Michael Ryan Clark (Columbia University (US))\nBose- Einstein correlations between identified charged pions are measured for $p $+Pb\ncollisions at $\\sqrt{s_{\\mathrm{NN}}}=5.02~\\mathrm{TeV}$ with the ATLAS detector with \na total integrated luminosity of $28~\\inb$.

In small sy stems\, such as in proton- or deuteron-nucleus collisions\, they are usefu l benchmarks of the effects of the nuclear environment on the initial part on densities or the emerging jet energy. In nucleus-nucleus collision syst ems\, they are sensitive probes of the energy loss experienced by the show ers of hard-scattered partons that traverse the hot QCD medium. We present recently published PHENIX results on fully reconstructed jet production r ates in 200 GeV proton-proton and deuteron-gold collisions\, and a prelimi nary measurement in copper-gold collisions. In particular\, the deuteron-g old measurement has revealed that the traditional frameworks used to under stand the collision geometry of small systems break down in extreme hard-s cattering kinematic regimes.

The collisions between particles are included in the relaxation time approximation specified by different values of the shear viscosity to entropy density ratio. At first we show that\, to a good appr oximation\, the transverse-momentum spectra of the produced patrons are ex ponential\, irrespectively from the assumed value of the viscosity of the system and the freeze-out time. This thermal-like behaviour may be attribu ted to specific properties of the Schwinger tunneling process. In the next step\, in order to check the approach of the system towards genuine local equilibrium\, we compare the local slope of the model transverse-momentum spectra with the local slope of the fully equilibrated reference spectra characterised by the effective temperature that reproduces the energy dens ity of the system. We find that the viscosity corresponding to the AdS/CFT lower bound is necessary for thermalization of the system within about tw o fermis. \n\nReferences:\n\n1) R. Ryblewski\, W.

In the regime\n of low Bjorken x\, one enters in the no nlinear regime of gluon\n saturation\, where the gluons are better describ ed as a strong\n coherent semi-classical field than as a collection of qua si\non-shell partons. Hence\, that regime lies outside the validity\n rang e of the collinear factorization\, and is better described \nwithin the di pole factorization of DIS observables which allows \nto resum coherent mul tiple scattering on the target\, and also \nto resum the high-energy leadi ng logarithms (LL).\nOne of the motivations to study in detail the regime of gluon \nsaturation in proton and nuclei is that it drives the physics \ nof the earliest stages of heavy collisions\, up to the formation \nof the Quark-Gluon Plasma.\n\nSo far\, phenomenological studies have been perfor med successfully\n at LO in the dipole factorization\, with LL resummation \,\n using HERA data for proton DIS. However\, in order to reach \nprecisi on\, NLO corrections should be included\, as well as\nhigh-energy NLL resu mmations. This is important not only to extract \nas much knowledge as pos sible out of the HERA data\, but also in\nprevision of future electron-pro ton and/or electron-nucleus colliders. \n\nIn this talk\, I will present an update on the calculation of the \n(fixed order) NLO corrections to DIS structure functions on a dense \ntarget in the dipole factorization pictu re. In earlier studies\, only \none part of the NLO corrections has been c alculated\, the one \ncorresponding to a quark-antiquark-gluon Fock state interacting with\nthe target. By contrast\, I will present the first direc t calculation of \nthe other part of NLO corrections\, for which a quark-a ntiquark Fock \nstate interacts with the target. I will also discuss issue s related \nwith the combination of the two pieces\, which is complicated by the \npresence of UV divergences. Along the way\, various techniques ha ve been \ndevelopped\, which will simplify the calculation of NLO correcti ons\nto most other observables relevant for gluon saturation.\n\nhttps://i ndico.cern.ch/event/469857/contributions/1978364/ LOCATION:Centro de Congressos\, Instituto Superior Técnico\, Alameda Camp us Room 02.2 URL:https://indico.cern.ch/event/469857/contributions/1978364/ END:VEVENT BEGIN:VEVENT SUMMARY:The Initial Conditions in High-Energy pp Collisions DTSTART;VALUE=DATE-TIME:20160525T173000Z DTEND;VALUE=DATE-TIME:20160525T175000Z DTSTAMP;VALUE=DATE-TIME:20190325T174624Z UID:indico-contribution-192514-1978381@indico.cern.ch DESCRIPTION:Speakers: Cheuk-Yin Wong (Oak Ridge National Laboratory)\nThe initial conditions in high-energy pp collisions can be well\nexamined from the momentum distributions of both jets and hadrons in\nthese collisions\ , as they provide relevant information on the\ncollision mechanism and the initial properties of the produced medium.\nIt was found recently that in pp collisions at the LHC\, the hadron\ntransverse momentum distributions at central rapidity spanning 14\ndecades of magnitude over the pT domain f rom the lowest of ~0.5 GeV/c\nto the highest of ~200 GeV/c can be adequate ly described by a single\nTsallis distribution with only three apparent de grees of freedom [1].\nThe simplicity of the pT spectrum over such a large pT domain\, and the\nsubsequent hard-scattering model analysis of the jet and hadron\nmomentum distributions suggest indirectly that a single mecha nism\, the\nhard-scattering between partons\, dominates over almost the wh ole pT\ndomain in these high-energy collisions [2]. Direct evidence of su ch a\ndominance is further provided by the experimental observation of the \nsignature for the hard-scattering process\, as indicated by the\ntwo-par ticle angular correlations with minimum-pT-biased hadrons [3].\nOne is led naturally to the initial conditions that in\nhigh-multiplicity events in high-energy pp collisions\, parallel\nhard-scattering collisions of parton s generate both the jet and the\nbulk medium whose subsequent collisions l ead to the angular\ncorrelations of the near-side ridge\, as described in the momentum kick\nmodel for such correlations [4-7].\n\n[1] C.Y.Wong \, G .Wilk\, {Tsallis fits to pT spectra for pp collisions at\n LHC}\, Acta.

The results includ e contributions from both single-parton scattering (SPS) and double-parton scattering (DPS). The calculations are performed for kinematical situatio ns relevant for two experimental measurements (ATLAS and CMS) at the LHC. We compare our results to those reported by the ATLAS and CMS collaboratio ns for different sets of kinematical cuts. The results of the HEF approach are compared with their counterparts for collinear factorization. For sym metric cuts the DPS HEF result is considerably smaller than the one obtain ed with collinear factorization. The mechanism leading to this difference is of kinematical nature. We conclude that an analysis of inclusive 4-jet production with asymmetric pT-cuts below 50 GeV would be useful to enhance the DPS contribution relative to the SPS contribution. In contrast to the collinear approach\, the HEF approach nicely describes the distribution o f the ΔS variable\, which involves all four jets and their angular correl ations.\n\nhttps://indico.cern.ch/event/469857/contributions/1978368/ LOCATION:Centro de Congressos\, Instituto Superior Técnico\, Alameda Camp us Room 02.2 URL:https://indico.cern.ch/event/469857/contributions/1978368/ END:VEVENT BEGIN:VEVENT SUMMARY:Nuclear glue constraints from top-quark pair production in p-A and A-A collisions at the LHC and beyond DTSTART;VALUE=DATE-TIME:20160524T141000Z DTEND;VALUE=DATE-TIME:20160524T143000Z DTSTAMP;VALUE=DATE-TIME:20190325T174624Z UID:indico-contribution-192514-1978334@indico.cern.ch DESCRIPTION:Speakers: David d'Enterria (CERN)\nI will present phenomenolog ical studies of top-quark pair production in p-Pb and Pb-Pb collisions at the CERN LHC and at the future circular collider (FCC)\, obtained with NLO pQCD calculations including nuclear PDFs.

In asymmetric Cu+Au colli sions\, due to the difference in the number of spectators\, not only the m agnetic field but also a strong electric field (E-field) would be created along the reaction plane and pointing from the Au-nucleus to Cu-nucleus. T he lifetime of the E-field would be very short\, of the order of a fractio n of a fm/c. The quarks and antiquarks that have been already produced at this time would experience the Coulomb force\, which results in charge sep aration of directed flow. Thus\, the measurement of the charge-dependent d irected flow in Cu+Au provides an opportunity to study the time dependence of light quark production in heavy-ion collisions. Understanding the time evolution of the quark densities is also very important for detailed theo retical predictions of the Chiral Magnetic Effect and Chiral Magnetic Wave \, which various experiments are actively searching for.\n\nIn this talk\, the charge-dependent directed flow in Cu+Au collisions at \\sqrt{s_{NN}} =200 GeV measured in the STAR experiment will be presented. \nThe results are compared with existing model predictions. Implications for the dynamic s of quark production and system evolution will be discussed. Higher-harmo nic flow will be also presented and compared with results in A+A collision s.\n\nhttps://indico.cern.ch/event/469857/contributions/1978355/ LOCATION:Centro de Congressos\, Instituto Superior Técnico\, Alameda Camp us Room 02.1 URL:https://indico.cern.ch/event/469857/contributions/1978355/ END:VEVENT BEGIN:VEVENT SUMMARY:Incoherent diffraction and proton structure fluctuations DTSTART;VALUE=DATE-TIME:20160525T144000Z DTEND;VALUE=DATE-TIME:20160525T150000Z DTSTAMP;VALUE=DATE-TIME:20190325T174624Z UID:indico-contribution-192514-1978382@indico.cern.ch DESCRIPTION:Speakers: Heikki Mäntysaari (Brookhaven National Laboratory)\ nExclusive vector meson production can be used to directly probe the gluon density of a hadron. Measuring the cross section differentially in moment um transfer t makes it possible to determine the transverse density profil e (via coherent diffraction) and density fluctuations (incoherent diffract ion) of the target hadron. This knowledge on the geometric fluctuations of the proton\nis particularly important for understanding collective phenom ena observed in proton-nucleus collisions.\n\nWe calculate coherent and in coherent diffractive vector meson production in photon-proton and photon-n ucleus scattering in the Color Glass Condensate framework. The dipole mode l used in the calculation is constrained by the proton structure function data. By implementing sub-nucleon scale fluctuations using the constituent quark model or the IP-glasma framework we demonstrate that incoherent gam ma-p scattering is sensitive to small-scale fluctuations. We also show tha t the effect of geometric fluctuations can be disentangled from saturation scale fluctuations. \n\n We discuss to what extent the current HERA diffr active deep inelastic scattering data can be used to constrain the proton structure fluctuations and how an Electron Ion Collider (EIC) can improve the picture.\n\nhttps://indico.cern.ch/event/469857/contributions/1978382/ LOCATION:Centro de Congressos\, Instituto Superior Técnico\, Alameda Camp us Room 02.2 URL:https://indico.cern.ch/event/469857/contributions/1978382/ END:VEVENT BEGIN:VEVENT SUMMARY:Entanglement entropy and the Color Glass Condensate DTSTART;VALUE=DATE-TIME:20160524T145000Z DTEND;VALUE=DATE-TIME:20160524T151000Z DTSTAMP;VALUE=DATE-TIME:20190325T174624Z UID:indico-contribution-192514-1978345@indico.cern.ch DESCRIPTION:Speakers: Michael Lublinsky ()\nWe compute the entanglement en tropy of soft gluons in the wave function of a fast moving hadron and disc uss its basic properties.

Photoproduction of heavy ve ctor mesons (J/psi\, Upsilon) thus provide direct information on the gluon distribution functions in the nucleon/nucleus at very low values of Bjork en-x. The CMS experiment has excellent capabilities for the measurement of the heavy vector mesons in the dimuon decay channel using the tracker and the muon chambers. The measured coherent J/psi photoproduction cross sect ion in ultraperipheral Pb-Pb collisions using 2011 PbPb data and Upsilon p hotoproduction in ultraperipheral pPb collisions during 2013\, will be pre sented.

We study two small-x observables at forward rapidity: dijet azimuthal correlations in proton-nucleus collisions\, and induced co herent spectrum associated with single parton scattering. Both observables are first analyzed from a CGC (color glass condensate) starting point of view\, and then generally expressed in terms of TMD (transverse momentum d ependent)  gluon distributions.
