These topologies include acopla nar photons\, non-pointing single photons\, acoplanar leptons\, large impa ct parameter leptons\, detached slepton decay vertices\, heavy stable char ged sleptons and four lepton plus missing energy final states. No evidence for these new phenomena is observed and limits on production cross-sectio ns and sparticle masses are derived. A scan of the minimal GMSB parameter space was performed and a model dependent lower limit of about 45 GeV on t he next-to-lightest supersymmetric particle (NLSP) mass and of about 9 TeV on the parameter L was derived\, independently of the NLSP lifetime.Organ iser(s): Fabiola Gianotti/ EP DivisionNote: Tea & coffee will be served at 16.00 hrs.\n\nhttp://indico.cern.ch/conferenceDisplay.py?confId=a032805 LOCATION:CERN Main Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a032805 END:VEVENT BEGIN:VEVENT SUMMARY:Search for Higgs boson(s) with L3 DTSTART;VALUE=DATE-TIME:19990906T143000Z DTEND;VALUE=DATE-TIME:19990906T144500Z DTSTAMP;VALUE=DATE-TIME:20130523T171549Z UID:indico-event-a032806@cern.ch DESCRIPTION:The search for the Higgs boson(s) by the L3 experiment will be \nreviewed.

The particle mo menta and their multiplicity in jets are analysed in the context of the Mo dified Leading Log Approximation. The analysis shows that perturbative \nQ CD methods work at very low cut-off scales of 200-3000 MeV. The results ar e compared to those from LEP. The analysis also suggests a very simple had ronization with an approximately one-to-one correspondence between hadrons and final shower partons. I will report on the measurement of the ratio o f the number of charged particles in gluon and quark jets\, r = 1.7 ± 0.1 . The measurement of this value at LEP has been a long standing problem: o ver the last ten years it slowly drifted from the earlier 1.02 ± 0.07 res ult to the most recent 1.51 \n± 0.04. The transition from minimum-bias (s oft) events to those that we associate with hard-scattered partons is also discussed.

Existing high-energy colliders (LEP and Tevatron) have alrea dy joined these searches and set constraints on the strength of gravity at short range. New results from the Tevatron are going to be reviewed. The most interesting opportunities in probing large extra dimensions will beco me available with the next generation of hadron colliders: the upgraded Te vatron and especially LHC\, where the ultimate tests of the new models of gravity will be done. I'll discuss various effects of large extra dimensio ns that can be seen experimentally\, existing limits on the properties of space with large extra dimensions\, new ideas in theory of quantum gravity \, as well as strategies and the reach of the next generation of Cavendish type experiments and accelerator searches.Organiser(s): Fabiola Gianotti / EP DivisionNote: Tea & coffee will be served at 16.00 hrs.\n\nhttp://ind ico.cern.ch/conferenceDisplay.py?confId=a032797 LOCATION:CERN Main Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a032797 END:VEVENT BEGIN:VEVENT SUMMARY:HERA-B: achievements\, deficit and prospects DTSTART;VALUE=DATE-TIME:20010514T143000Z DTEND;VALUE=DATE-TIME:20010514T153000Z DTSTAMP;VALUE=DATE-TIME:20130523T171549Z UID:indico-event-a032819@cern.ch DESCRIPTION:The year 2000 was the first year of commissioning for the HERA -B detector and for taking data in various trigger modes. Despite the obvi ous failure to be a competitive B-factory\, HERA-B is a pioneering experim ent and the most powerful and advanced multi-particle spectrometer for hig h rate environments.

A review of the latest results from this data s et including CKM matrix determinations\, rare B decays and searches for CP violation will be presented and compared to results from BABAR and Belle. The status of the CLEO III detector and data set will also be summarised. \nCharm acts as a staging area\, both experimentally and theoretically\, f or the assault on B physics. Accordingly\, the CLEO collaboration is prepa ring a proposal to operate CLEO and CESR\, as a Charm factory in the centr e of mass energy range between 3-5 GeV. Data taking in this energy range i s planned to begin in January 2003. Data samples of 1-3 fb-1/yr are expect ed\, (6 million tagged D decays) this will allow the determination of char m decay constants and the CKM matrix elements Vcd and Vcs to a precision o f several percent\, charm absolute branching ratios to 1-3%\, and precisio n tests of the unitarity of the CKM matrix. Searches for D mixing\, rare d ecays and CP violation in the charm sector will also be made. In a year's run\, over 1 billion J/Y's can be produced at CESR. When combined with dat a to be taken later this year at the narrow ° resonances\, we will obtain unique precision information that will be a rich and efficient testing gr ound for lattice QCD. The potential exists to significantly advance our un derstanding and control over strongly-coupled\, non-perturbative quantum f ield theories in general and QCD in particular. An understanding of strong ly-coupled theories will be a crucial element in helping to understand new phenomena at the high energy frontier.Organiser(s): Ariane Frey / EP Divi sionNote: Tea & coffee will be served at 16.00 hrs.\n\nhttp://indico.cern. ch/conferenceDisplay.py?confId=a032820 LOCATION:CERN Main Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a032820 END:VEVENT BEGIN:VEVENT SUMMARY:A Continuous Coherent Lyman-alpha source for Antihydrogen Experime nts DTSTART;VALUE=DATE-TIME:20010618T143000Z DTEND;VALUE=DATE-TIME:20010618T153000Z DTSTAMP;VALUE=DATE-TIME:20130523T171549Z UID:indico-event-a032798@cern.ch DESCRIPTION:Two experiments\, ATRAP and ATHENA are now underway at CERN's new antiproton decelerator AD with the goal to produce and to investigate cold antihydrogen atoms.

For this reason large photomultipliers\, mounted in pressure spher es\, are deployed into the deep (> 1.5km) Antarctic glacier. These photomu ltipliers detect Cherenkov light emitted by charged secondary particles\, which are produced in neutrino interactions inside or close to the detecto r.\nThe talk highlights the detection of high energy atmospheric neutrinos \, the search for extraterrestrial neutrinos\, neutrinos from WIMP annihil ation in the centre of the earth and relativistic magnetic monopoles. Thes e results were obtained with the first stage detector AMANDA-B consisting of 302 PMs in 1997. The status of the currently \noperating AMANDA-II dete ctor (680 PMs) and an outlook on the ICECUBE project are given. The ICECUB E project aims to instrument a volume of 1km_ deep ice with about 5000 pho totubes.\n\nOrganiser(s): Ariane Frey / EP DivisionNote: * Tea & coffee wi ll be served at 16.45 hrs.\n\n\nhttp://indico.cern.ch/conferenceDisplay.py ?confId=a032827 LOCATION:CERN URL:http://indico.cern.ch/conferenceDisplay.py?confId=a032827 END:VEVENT BEGIN:VEVENT SUMMARY:Measurement and QCD Interpretation of the Inclusive Deep-Inelastic Scattering Cross Section by H1\n DTSTART;VALUE=DATE-TIME:20011008T143000Z DTEND;VALUE=DATE-TIME:20011008T153000Z DTSTAMP;VALUE=DATE-TIME:20130523T171549Z UID:indico-event-a032824@cern.ch DESCRIPTION:Deep inelastic electron proton collisions are a straightforwar d tool to study the QCD dynamics between quarks and gluons in the proton. A recent measurement and QCD analysis of the deep inelastic scattering cro ss section by the H1 experiment at HERA are presented.\nIn a NLO QCD analy sis of H1 structure function data\, the gluon distribution in the proton i s extracted to typically 3% experimental accuracy at low Bjorken x.. In a combined analysis of H1 and high precision µp data by the CERN muon exper iment BCDMS\, the gluon distribution at low x and the strong coupling cons tant as were for the first time extracted simultaneously.The strong coupli ng constant is determined with about 1% experimental accuracy\, and QCD at NLO is confirmed over 5 orders of magnitude of Bjorken x at a new level o f precision.Organiser(s): Ariane Frey / EP DivisionNote: Tea & coffee will be served at 16.00 hrs.\n\nhttp://indico.cern.ch/conferenceDisplay.py?con fId=a032824 LOCATION:CERN Main Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a032824 END:VEVENT BEGIN:VEVENT SUMMARY:Semi-leptonic\, Weak-radiative and FCNC Decays of Hyperons and Kao ns as a Window into Fundamental Processes\n DTSTART;VALUE=DATE-TIME:20011015T143000Z DTEND;VALUE=DATE-TIME:20011015T153000Z DTSTAMP;VALUE=DATE-TIME:20130523T171549Z UID:indico-event-a032828@cern.ch DESCRIPTION:Recent results from KTEV with Hyperon beta and weak-radiative decays\, and new measurements from the HyperCP experiment on Flavour Chang ing Neutral Currents and rare K14 decays will be presented. The common thr ead in this diverse collection of decays is an attempt to improve our unde rstanding of weak processes at the quark-diagram level by either confirmin g the decay of mechanism of the Standard Model or demonstrating that new p hysics is required.

The high energy and l uminosity achieved by LEP provides plenty of data on two-photon processes. Charm production has been studied in more detail\, including various diff erential cross-sections and the measurement of the charm structure functio n of the photon in single-tag two-photon events\, while for the heavier be auty quark only the total cross-section has been measured. In most cases t he NLO predictions are in agreement with the data\, but some discrepancies are observed in the low-x region of the charm structure function and also the total beauty cross-section\, indicating that our present understandin g of these processes is far from complete.\nA summary of the recent experi mental results on heavy flavour production in two-photon processes will be presented\, with an outlook on possible extensions of the measurements at a future e+e- linear collider. \n\nOrganiser(s): Ariane Frey / EP Divisio nNote: * Tea & coffee will be served at 16.00 hrs.\n\nhttp://indico.cern.c h/conferenceDisplay.py?confId=a032829 LOCATION:CERN Main Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a032829 END:VEVENT BEGIN:VEVENT SUMMARY:Direct Detection of Dark Matter Particles with Underground Experim ents DTSTART;VALUE=DATE-TIME:20011210T153000Z DTEND;VALUE=DATE-TIME:20011210T163000Z DTSTAMP;VALUE=DATE-TIME:20130523T171549Z UID:indico-event-a032831@cern.ch DESCRIPTION:The existence of Dark Matter\, first pointed out some 70 years ago\, is nowadays one of the pillars of the new cosmological paradigm. It s mostly non-baryonic nature and its presence at galactic scales are also two well-based hypotheses in which rely some of the on-going experimental efforts to detect it. In this talk I will briefly review the basics of the direct detection of Weakly Interacting Massive Particles (WIMPs) with und erground experiments. This relatively new experimental field is now progre ssing fast\, as proven by the increasing number and size of groups which a re involved in these types of experiments and the number of papers studyin g its theoretical and phenomenological aspects. This development\, togethe r with the recent amount of information coming from cosmological observati ons\, has reduced considerably the sources of uncertainty typically attrib uted to this topic. I will briefly describe the present experimental situa tion\, focusing on my own experience as a member of the IGEX Dark Matter e xperiment being carried out at the Canfranc Underground Laboratory in the Spanish Pyrenees. The latest results of this experiment will be presented. These are comparable with the best exclusion limits and in \nparticular b egin to test the controversial result of the DAMA collaboration\, which cl aims to have already detected a WIMP. I will finish with the perspectives of this field to eventually detect and identify unambiguously a WIMP as a constituent of the Dark Matter galactic halo.Organiser(s): Ariane Frey / E P DivisionNote: Tea & coffee will be served at 16.00 hrs.\n\nhttp://indico .cern.ch/conferenceDisplay.py?confId=a032831 LOCATION:CERN Main Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a032831 END:VEVENT BEGIN:VEVENT SUMMARY:Highlights from DIRAC DTSTART;VALUE=DATE-TIME:20011217T153000Z DTEND;VALUE=DATE-TIME:20011217T163000Z DTSTAMP;VALUE=DATE-TIME:20130523T171549Z UID:indico-event-a032830@cern.ch DESCRIPTION:A precise measurement of the lifetime of pionium\, a p+p- boun d state\, can provide a precise determination of the difference between th e pion-pion S-wave scattering lengths with I=0\,2\, a0-a2. The knowledge o f meson-meson threshold parameters provides a mean to test low energy QCD predictions\, which\, for the pion-pion system\, have reached a high degre e of accuracy. The DIRAC experiment is measuring the lifetime of pionium\, of order of some femtoseconds\, with a few percent precision. An outline of the experiment and its physics motivation\, the description of the meas urement method and the presentation of preliminary results from available data\, will be the topics of this seminar.Organiser(s): Ariane Frey / EP D ivisionNote: * Tea & coffee will be served at 16.00 hrs.\n\n\nhttp://indic o.cern.ch/conferenceDisplay.py?confId=a032830 LOCATION:CERN Main Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a032830 END:VEVENT BEGIN:VEVENT SUMMARY:Results on mixing in the D0 System from BaBar DTSTART;VALUE=DATE-TIME:20020114T153000Z DTEND;VALUE=DATE-TIME:20020114T163000Z DTSTAMP;VALUE=DATE-TIME:20130523T171549Z UID:indico-event-a032832@cern.ch DESCRIPTION:Mixing in the D0 system may provide a sensitive probe for new physics beyond the Standard Model (SM). The SM predictions are small (-3) for the mixing parameters x\, y which\, in the absence of CP-violation\, m easure the mass (x = DM/G) and lifetime (y = DG/2G) difference of the CP-e igenstates in the D0 system. New physics may significantly enhance x while y is expected to be dominated by SM processes.\nThe BaBar detector at the e+e- storage ring PEP-II provides the opportunity of studying charm decay s with unprecedented statistics and purities. Two experimental methods wil l be described in detail: The determination of y from the D0 lifetime diff erence in the decays K-p+ and K-K+ \, and the extraction of y\, x2 and the wrong-sign (D0 -> K+p-) decay rate from the time evolution of the D0 deca y rate. Preliminary BaBar results for y and the wrong-sign decay rate will be presented.Organiser(s): Ariane Frey / EP DivisionNote: Tea & coffee wi ll be served at 16.00 hrs.\n\nhttp://indico.cern.ch/conferenceDisplay.py?c onfId=a032832 LOCATION:CERN Main Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a032832 END:VEVENT BEGIN:VEVENT SUMMARY:Very accurate mass measurements of exotic nuclides - is the Standa rd model concerned?

Under the condition that the exotic nucleus is well eno ugh known it supplies an easy-to-access laboratory for investigation of th e weak \ninteraction. The mass is beside the half-life and decay mode one of the \ngross properties that characterise this laboratory. Direct mass m easurement techniques that are based on a frequency determination yield re lative uncertainties as small as 10 ppb and are applicable to nuclides wit h half-lives as short as 50 ms. Hence\, even very exotic nuclei can be inv estigated with the necessary accuracy for tests of the Standard model of w eak interaction. These are the CVC hypothesis and the unitarity of the CKM matrix along with the quest for scalar currents. The techniques will be p resented and as examples mass measurements of 32\,33\,34 Ar\, 74 Rb and 74 Kr will be discussed.\n\nOrganiser(s): Ariane Frey / EP DivisionNote: Tea & coffee will be served at 16.00 hrs.\n\nhttp://indico.cern.ch/conference Display.py?confId=a032833 LOCATION:CERN Main Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a032833 END:VEVENT BEGIN:VEVENT SUMMARY:Nuclear emulsion techniques in the CHORUS experiment DTSTART;VALUE=DATE-TIME:20020218T153000Z DTEND;VALUE=DATE-TIME:20020218T163000Z DTSTAMP;VALUE=DATE-TIME:20130523T171549Z UID:indico-event-a032834@cern.ch DESCRIPTION:Nuclear emulsion has the best spatial resolution among visual detectors. In recent years\, nuclear emulsion is used as a high resolution tracking device combined with electronic detectors in accelerator experim ents. It is emphasised that drastic improvements in the fully automatic em ulsion scanning microscopes enable us to analyse a large amount of events. The CERN WA95/CHORUS experiment was originally designed to search for n m -> n t oscillation in the CERN Wide Band Neutrino Beam. The apparatus is an emulsion-based hybrid setup\, consisting of a nuclear emulsion target f ollowed by electronic detectors. Using nuclear emulsion as an active targe t\, the production of a t lepton can be recognised by detecting its short decay path. This method is used to search for neutrino oscillation. Since the lifetime of charmed particles is similar to that of the t lepton\, the experiment is also suitable to study charm physics. For the second run of the experiment\, three layers of emulsion tracker system were installed i n addition to the original hadronic spectrometer to perform high resolutio n momentum measurements. This is another application of the emulsion techn ique in the CHORUS experiment. In this talk\, the role of \nnuclear emulsi on in the CHORUS experiment\, the emulsion target and the emulsion tracker \, and recent results on neutrino oscillation and charm physics are presen ted.\n\nOrganiser(s): Ariane Frey / EP DivisionNote: Tea & coffee will be served at 16.00 hrs.\n\nhttp://indico.cern.ch/conferenceDisplay.py?confId= a032834 LOCATION:CERN Main Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a032834 END:VEVENT BEGIN:VEVENT SUMMARY:Jet Physics in Deep-Inelastic Scattering at HERA\n DTSTART;VALUE=DATE-TIME:20020318T153000Z DTEND;VALUE=DATE-TIME:20020318T163000Z DTSTAMP;VALUE=DATE-TIME:20130523T171549Z UID:indico-event-a032835@cern.ch DESCRIPTION:After a short introduction to (jet) physics at HERA\, recent r esults on DIS jet physics from the HERA collaborations H1 and ZEUS are rev iewed. Topics covered are\, among others\, multi-jet cross-section measure ments\, determinations of the strong coupling parameter aS and the gluon d ensity and jet measurements at the highest photon virtualities Q2 accessib le at HERA. It is shown that over a wide range of phase-space NLO QCD calc ulations deliver a satisfactory description of the data.

This improvement will open new prospects for studies of fundamental prop erties of the neutron and its decay. As a first experiment we intend to im prove the sensitivity in the measurement of the neutron electric dipole mo ment (EDM) to about 5 x 10-28 e cm\, i.e. about a factor of 100 improvemen t over presently published limits. A finite value at this level - as predi cted by Supersymmetry - would be unambiguous evidence for CP violation bey ond the Standard Model. The EDM spectrometer employs the conventional Rams ey method\, but makes use of a system of 8 HV chambers and 5 chambers with out HV\, which will reduce the influence of systematic effects due to magn etic problems and leakage currents considerably. We shall discuss the prin ciple of the experiment\, the expected statistical uncertainty\, systemati c effects as well as details of the most important parts.Organiser(s): Ari ane Frey / EP DivisionNote: More info via reinhold.henneck@psi.ch\n\nTea & coffee will be served at 16.00 hrs.\n\nhttp://indico.cern.ch/conferenceDi splay.py?confId=a032840 LOCATION:CERN Main Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a032840 END:VEVENT BEGIN:VEVENT SUMMARY:The final NA48 result on direct CP Violation DTSTART;VALUE=DATE-TIME:20020625T143000Z DTEND;VALUE=DATE-TIME:20020625T153000Z DTSTAMP;VALUE=DATE-TIME:20130523T171549Z UID:indico-event-a032838@cern.ch DESCRIPTION:The NA48 experiment to determine the direct CP violation param eter epsilon'/epsilon precisely has ended after 6 years of preparations an d 5 years of data taking.\nThe most recent and concluding measurement of t he direct CP violation parameter epsilon'/epsilon in neutral kaon decays i s presented.

Virgo is a large suspended Michelson in terferometer currently being developed near Pisa. Before the availability of the complete detector\, some preliminary activities have been taking pl ace on its central part (CITF) between spring 2001 and summer 2002\, in or der to validate the instrument design and the suspended interferometer con trols. After a summary of the current status of Virgo\, the main results o f these experimental tests are presented\, in particular the first sensiti vity curves of the CITF\, which are then compared with current sensitiviti es of similar detectors in the world. The experience accumulated with the CITF experimentation will be directly useful for the commissioning of the full Virgo interferometer scheduled to start in mid-2003. Finally\, the ma in sources of GW and the corresponding data analysis methods are briefly s ummarized.Organiser(s): C.

Heavy quark p airs are mainly produced in ep interactions via the fusion of the exchange d photon with a gluon from the proton. The measurement of the heavy quarks production provides due to the high mass of the quarks a good test of per turbative QCD calculations and yields information about the structure of t he proton and the photon. At HERA the production of b quarks is strongly s uppressed compared to the production of c quarks. The different methods to tag b quarks are reviewed\, in particular the identification of b hadrons via a life time measurement using the central silicon detector of the H1 experiment is explained in more detail. Experimental results are presented and compared to theoretical predictions.Organiser(s): C.

In the final stage the telescope will consist of 12 strings equipped with 900 photomultipliers that instrument an effective volume of 0.03 km3. The reconstruction of the neutrinos is performed via Cherenkov light emitted by electrons or muons which are generated by the interaction s of the neutrinos in water or rock. The objective is the measurement of t he diffuse cosmic-neutrino flux\, its angular and energy spectrum and the search for point sources as well as the search for signals from WIMPs and other exotic particles.\nIn the context of the planning for a larger succe ssor telescope the possibility of the neutrino detection by acoustic signa ls is currently investigated intensively. The interaction of a neutrino in water induces a shower which\, according to the thermo-acoustic model\, l eads to a pressure wave. The advantage of using sound instead of light as the "detection medium" is its approximately 10 times longer range in water potentially allowing to equip a much larger volume with detectors.Organis er(s): C.

The spectrometer has been designed to address a large range of physics topics with hadron and muon beams. Giv en that no hadron data has been collected yet the presentation will focus on the physics program with the polarized muon beam.\n The main objective of this program is to study the spin structure of the nucleon\, i.e. to d etermine how the nucleon spin is shared among its constituents. In analogy to the unpolarized case deep inelastic scattering of polarized leptons of f polarized nucleon targets provides access to the polarizations of quarks and gluons.\n Triggered by the discovery of EMC at CERN in 1988\, that t he spin contribution of the quarks is small\, a series of experiments at C ERN\, DESY and SLAC measured this contribution more precisely and found th at in fact only about 30% of the nucleon spin is carried by quarks. Conseq uently a second generation of experiments has been started to search for t he missing 70% of the nucleon spin. These experiments concentrate on the d etermination of the gluon polarisation ΔG/G. At COMPASS this quantity can be measured directly via the so-called photon-gluon fusion process.\n CO MPASS has started to take data with a 160 GeV muon beam and a polarized de uteron target in 2002 and has since then collected three years of data in this configuration. First physics results from 2002 and 2003 data - includ ing the first determination of ΔG/G by COMPASS - will be presented.Organi ser(s): Christoph Amelung / PH-EPNote: Tea & coffee will be served at 16.0 0 hrs.\n\nhttp://indico.cern.ch/conferenceDisplay.py?confId=a044463 LOCATION:CERN Main Auditorium URL:http://indico.cern.ch/conferenceDisplay.py?confId=a044463 END:VEVENT BEGIN:VEVENT SUMMARY:Pion and Kaon production in heavy-ion collisions around 1-2 AGeV DTSTART;VALUE=DATE-TIME:20041115T153000Z DTEND;VALUE=DATE-TIME:20041115T163000Z DTSTAMP;VALUE=DATE-TIME:20130523T171549Z UID:indico-event-a044820@cern.ch DESCRIPTION:Heavy-ion collisions provide the unique possibility to study b aryonic matter well above saturation density. The conditions inside the de nse reaction zone and the in-medium properties of hadrons can be explored by measuring the particles created in such collisions. In particular\, the production of strange mesons at beam energies below or close to their res pective threshold in binary nucleon-nucleon collisions is well suited for these studies. The production of K+ and of K- mesons as well as of pions i n heavy-ion collisions at beam energies of 1 to 2 AGeV has systematically been investigated with the Kaon Spectrometer KaoS at the heavy-ion synchro tron SIS at the GSI in Darmstadt\, Germany. The ratio of the K+ production excitation function for Au+Au and for C+C reactions increases with decrea sing beam energy\, which is expected for a soft nuclear equation-of-state. The K-/K+ ratio is found to be nearly constant as a function of the colli sion centrality and can be explained by the dominance of strangeness excha nge. On the other hand the spectral slopes and the polar emission patterns are different for K- and for K+. Furthermore the azimuthal distribution o f the particle emission has been investigated. K+ mesons and pions are emi tted prefentially perpendicular to the reaction plane as well in Au+Au as in Ni+Ni collisions. In contrast for K- mesons in Ni+Ni reactions an in-pl ane flow was observed for the first time at these incident enegies.Organis er(s): C.

The presentation will focus on the thermoelastic design\, construction and tests of prototype cryogenic silicon detector modules. Such modules are nearly entirely built out of si licon in order to minimize thermal stress and temperature gradients along the module. The cooling is done with two-phase flow of argon through capil lary pipes embedded in a carbon fiber composite spacer close to the heat s ources. Measurements of the thermoelastic properties of radiation-hard epo xies filled with fused quartz powder at low temperature will be summarised .

The understand ing of diffractive scattering at high energies\, where the proton stays in tact and loses only a small fraction of its incoming momentum\, represents one of the most important challenges in the understanding of QCD at the b order of the applicability of perturbative methods. In diffractive deep-in elastic scattering at HERA\, the structure function of the colourless exch ange has been precisely measured and\, according to a QCD factorization th eorem\, interpreted in terms of diffractive parton distributions. At HERA as well as the TEVATRON\, in particular hard diffractive processes such as jet or heavy quark production are studied. Of particular interest is the observation that the measured cross sections of these processes both in ph otoproduction at HERA as well as at the TEVATRON are significantly below N LO QCD calculations based on diffractive parton distributions. Possible re asons for this breakdown of factorization will be discussed. I will also b riefly discuss results on diffractive Vector Meson production and Deeply V irtual Compton Scattering (DVCS) at HERA. Finally\, I will give an outlook on the plans regarding diffractive physics at the LHC experiments\, which include for example the search for new physics.Organiser(s): C.

The top quark is expected to decay in almost 100% of cases into a W-boson and a b-quark. The identification of b-quark jets is crucial to te st this prediction. CDF and Dzero data do not exclude that the heavy quark with mass of 175 GeV is an exotic quark with charge 4e/3\, unless a twofo ld ambiguity is lifted by separating b-quark from anti b-quark jets. \nTo this end\, a jet charge algorithm is applied to the Dzero data which allow s to discriminante between an exotic quark with charge 4e/3 and a standard model top quark with charge 2e/3.Organiser(s): M.

The characteristics of the very-high-energy gamma ray emis sion indicates efficient particle acceleration in the vicinity of the puls ar which is thought to be powered by the loss of the pulsar's rotational e nergy. Recently\, the H.E.S.S. experiment\, a system of imaging atmospheri c Cherenkov telescopes dedicated to the detection of gamma rays with energ ies between 100 GeV and 100 TeV\, discovered numerous pulsar-associated Te V gamma ray sources allowing for detailed studies of the high energy emiss ion and possible particle acceleration mechanisms.

This talk focuses on measurements of one of the top q uark properties performed by CDF: the helicity of the W-boson from top qua rk decay. Three different methods for measuring the W-helicity from top de cay are discussed. These measurements are based on data samples correspond ing to integrated luminosities up to 1 fb-1.

The nucleus ground state c an be described in terms of electromagnetic quadrupole moments. Magnetic d ipole and quadrupole moments are very sensitive to all types of correlatio ns and provide important benchmarks in the studies of the nuclear potentia l. The nuclear shape does not only vary with proton and neutron number\, b ut can also vary within the same nucleus\, since the nucleons can occupy d ifferent orbitals polarizing the nucleus in different ways. This phenomeno n is called the shape coexistence. It was studied in the case of the neutr on deficient krypton isotopes through the Coulomb excitation of radioactiv e ions beam at the SPIRAL facility at GANIL-Caen\, France.

These interactions can contribute s uch large corrections to the renormalization of superpartner masses that p redictions from commonly used spectrum codes (such as ISAJET\, SPHENO\, SO FTSUSY\, SUSPECT) may be completely wrong. The size of the new effects dep ends on the strength of interactions in the hidden sector\, and can easily be of order 1.

A strong excess of pairs is ob served above the yield expected from neutral meson decays. Its mass spectr um is consistent with a dominant contribution from π+π- -> ρ -> μ+μ- annihilation. The associated ρ spectral function shows a strong broadenin g\, but essentially no shift in mass. The results are discussed in the fra me of different theoretical approaches addressing hadron properties close to the QCD phase boundary. They rule out models linking hadron masses dire ctly to the value of the chiral condensate. \nBeyond the mass spectra of t he excess\, we have now a precision measurement of the associated transver se momentum spectra up to masses of 2.6 GeV. The slope parameters Teff ext racted from the spectra rise with dimuon mass up to the ρ\, followed by a sudden decline above. While the initial rise is consistent with the expec tations for radial flow of a hadronic decay source\, the decline signals a transition to an emission source with much smaller flow.

In these diffractive coll isions\, the proton stays intact but a hard scatter occurs which allows co mparison with perturbative QCD calculations. The universality of the diff ractive proton structure is investigated by comparing different hard scatt ering final states\, and by comparing collisions initiated through the exc hange of point-like photons with those induced by real photons.\n\nIn this talk I will review the HERA results which can be summarised as follows: W hile all point-like photon scattering processes (deep-inelastic scattering \, DIS) can be described using the same diffractive parton densities (fact orisation)\, the situation is different in real photon scattering where th e diffractive dijet cross section measured by H1 for E_T(jet1)>5 GeV\, E_T (jet2)>4 GeV is a factor of approximately 0.5 lower than expectations base d on the DIS parton densities (factorisation breaking). Strikingly\, this gap survival probability factor is independent of the photon energy that manifests itself outside the jet system---direct and resolved photon proce sses are equally suppressed. This behaviour is unexpected\, but can be und erstood qualitatively in the dipole picture of photon-proton scattering. I will also present latest results which indicate that the survival probab ility depends on the transverse energy of the jets.\n\nhttp://indico.cern. ch/conferenceDisplay.py?confId=32566 LOCATION:CERN Council Chamber ** URL:http://indico.cern.ch/conferenceDisplay.py?confId=32566 END:VEVENT END:VCALENDAR
