We show that such improvement is conceivable by fully exploiting innovations already introd uced by CAST\, namely\, x-ray focusing optics and low background x-ray det ectors\, as well as a new magnet with substantially enlarged magnetic volu me. If axions also couple to electrons\, the Sun produces a larger flux fo r the same value of the Peccei-Quinn scale\, allowing one to probe a broad er class of models. Except for the axion dark matter searches\, this exper iment will be the most sensitive axion search ever\, reaching or surpassin g the stringent bounds from SN1987A and possibly testing the axion interpr etation of anomalous white-dwarf cooling that predicts an axion mass of a few meV. Beyond axions\, this new instrument will probe entirely unexplore d ranges of parameters for a large variety of axion-like particles (ALPs) and other novel excitations at the low-energy frontier of elementary parti cle physics.\n\nhttp://indico.cern.ch/contributionDisplay.py?contribId=56& sessionId=8&confId=117804 LOCATION:Dogus University\, Istanbul\, Turkey URL:http://indico.cern.ch/contributionDisplay.py?contribId=56&sessionId=8& confId=117804 END:VEVENT BEGIN:VEVENT SUMMARY:Forward-backward asymmetry of top quark in unparticle physics.

The goal is to ex tend the data set from about 300 fb-1 proposed for LHC running to 3000 fb- 1 by around 2030. Coping with the high instantaneous and integrated lumino sity will require many changes to the ATLAS detector. ATLAS is planning a multi-phase detector upgrade procedure\, starting with initial modificatio ns of the existing detector setup as early as 2013 towards large scale rep lacements of detector components during later shut down periods. The desig ns are developing rapidly for an all-new inner-tracker\, big changes in th e calorimeter and muon systems\, as well as improved triggers.

Measurements are presented for both the inclusive top pair production cross section\, using the dilepton\, lepton+jets\, ha dronic and tau channels\, as well as for various differential cross sectio ns. The results are compared with standard model predictions and allow to search for possible presence of new physics. In particular\, measurements of the top pair invariant mass distribution are used to search for new par ticles decaying to top pairs. We extract the mass of the top quark using v arious methods\, including indirect constraints from the measured cross se ction. We measure total and differential cross sections for the electrowea k production of single top quarks in both t- and tW-channels\, also useful for constraining the CKM matrix element Vtb. Further results include meas urements of the W helicity in top decays and the top pair charge asymmetry .\n\nhttp://indico.cern.ch/contributionDisplay.py?contribId=64&sessionId=5 &confId=117804 LOCATION:Dogus University\, Istanbul\, Turkey URL:http://indico.cern.ch/contributionDisplay.py?contribId=64&sessionId=5& confId=117804 END:VEVENT BEGIN:VEVENT SUMMARY:Physics results from CMS DTSTART;VALUE=DATE-TIME:20110620T115000Z DTEND;VALUE=DATE-TIME:20110620T124000Z DTSTAMP;VALUE=DATE-TIME:20130619T160527Z UID:indico-contribution-117804-65@cern.ch DESCRIPTION:Speakers: SPAGNOLO\, Paolo ()\nThe talk shows the overview of the major results of the CMS experiment with data collected at LHC in the first year of run at 7 TeV.\n\nhttp://indico.cern.ch/contributionDisplay.p y?contribId=65&sessionId=5&confId=117804 LOCATION:Dogus University\, Istanbul\, Turkey URL:http://indico.cern.ch/contributionDisplay.py?contribId=65&sessionId=5& confId=117804 END:VEVENT BEGIN:VEVENT SUMMARY:Heavy-ion results from the CMS experiment DTSTART;VALUE=DATE-TIME:20110621T065000Z DTEND;VALUE=DATE-TIME:20110621T074000Z DTSTAMP;VALUE=DATE-TIME:20130619T160527Z UID:indico-contribution-117804-66@cern.ch DESCRIPTION:Speakers: KURT\, Pelin ()\nWe present early results of the CMS experiment from PbPb collisions at $srqrt{s_{NN}}$ = 2.76 TeV\, probing q uark and gluon matter at unprecedented values of energy density. The capab ilities of the CMS apparatus allows us to investigate various hard probes\ , as well as bulk particle production and collective phenomena\, using the calorimetry\, muon and tracking systems covering a large range in pseudor apidity\, complemented by a flexible two-level trigger system. One of the most important early observations was that dijets at high pT are found to be increasingly unbalanced as a function of collision centrality. The angu lar distribution of jet fragments has been also studied in these events in dicating a softening and widening of the subleading jet fragmentation patt ern. The overall pT-imbalance can be recovered by including tracks found a t low pT and at large angles with respect to the jet axis. Furthermore\, t he pT-distribution of charged tracks (jet fragments) has been measured usi ng various jet triggers\, extending to pT=200 GeV/c in pp collisions at 7 TeV\, and a reference spectrum is constructed to compare to PbPb collision s at 2.76 TeV/nucleon pair. The inclusive production of isolated prompt ph otons has also been studied in pp collision. The corresponding ongoing eff orts for PbPb collisions will be reviewed. CMS is also well equipped to me asure muons and dimuons in the high multiplicity environment of heavy ion collisions. Inclusive and differential measurements of the Z boson yield s how no sign of modification with respect to NLO pQCD calculations. Dimuon decays of the J/psi particle and the Upsilon family are also investigated and results will be presented for pp as well as for PbPb collisions. Two-p article correlations in both collision systems will be presented at variou s LHC beam energies\, and the complex two-dimensional structure with vario us short and long range correlation features in pseudorapidity will be dis cussed\, including the long range\, same-side ridge in high multiplicity p p and central PbPb events. Azimuthal angle correlations of charged hadrons were also measured as a function of transverse momentum\, centrality and pseudorapidity\, using the event-plane\, cumulant and Lee-Yang zeros metho ds\, featuring different sensitivities to non-flow correlations. An outloo k to odd Fourier-components of the azimuthal angle distributions will also be presented. Finally\, the transverse energy produced by the heavy ion c ollision as a function of centrality will be discussed as well\, in a wide range of pseudorapidity\, to help disentangle the interplay of initial st ate end final state effects on energy flow\, and to study the baryon energ y loss and the subsequent development of the pressure of the hot partonic system.\n\nhttp://indico.cern.ch/contributionDisplay.py?contribId=66&sessi onId=5&confId=117804 LOCATION:Dogus University\, Istanbul\, Turkey URL:http://indico.cern.ch/contributionDisplay.py?contribId=66&sessionId=5& confId=117804 END:VEVENT BEGIN:VEVENT SUMMARY:Status of the 4th SM Family DTSTART;VALUE=DATE-TIME:20110625T080000Z DTEND;VALUE=DATE-TIME:20110625T085000Z DTSTAMP;VALUE=DATE-TIME:20130619T160527Z UID:indico-contribution-117804-67@cern.ch DESCRIPTION:Speakers: Prof. SULTANSOY\, Saleh (TOBB-ETU)\nExistence of the fourth family follows from the basics of the standard model (SM) and the actual mass spectrum of the third family fermions. During the last two dec ades\, the fourth SM family studies were almost blocked by incorrect inter pretation of the precision electroweak data. Despite to the studies done 1 0 years ago this misinterpretation continued to have a place in Particle D ata Group (PDG) up to 2008. Lately (in 2010)\, authors of the correspondin g part of PDG have come close to common understanding. While there are som e indirect indications (BAU\, B-decays)\, the existence of the fourth SM f amily should be clarified by direct discovery of the fourth family quarks and leptons. Besides\, very important consequence of the fourth SM family is enhancement of the SM Higgs boson production at hadron colliders. We di scuss possible manifestations of the fourth SM family at existing and futu re colliders. The LHC and Tevatron potentials to discover the fourth SM fa mily have been compared.\n\nhttp://indico.cern.ch/contributionDisplay.py?c ontribId=67&sessionId=5&confId=117804 LOCATION:Dogus University\, Istanbul\, Turkey URL:http://indico.cern.ch/contributionDisplay.py?contribId=67&sessionId=5& confId=117804 END:VEVENT BEGIN:VEVENT SUMMARY:CAST physics achievements and perspectives DTSTART;VALUE=DATE-TIME:20110624T065000Z DTEND;VALUE=DATE-TIME:20110624T074000Z DTSTAMP;VALUE=DATE-TIME:20130619T160527Z UID:indico-contribution-117804-68@cern.ch DESCRIPTION:Speakers: Prof. ZIOUTAS\, Konstantin (Patras U.)\nThe CERN axi on helioscope CAST will be presented\, along with its results and the achi evements reached so far.

The necessary upgrades to enter into new territories i mply mainly detectors with less background and / or sub-keV energy thresh old.

Within the standard framework\, processes with an ob served hadron in the final state can be described in terms of perturbative hard-scattering cross sections and certain non-perturbative but universal fragmentation functions\, ending the details of the subsequent hadronizat ion process. We determine unpolarized fragmentation functions for the pion in LO and NLO from electron-positron annihilation data and based on a phe nomenological model.

In particular\, considering the therma l spectral density as well as additional operators coming up at finite tem perature\, the thermal QCD sum rules are acquired. Our numerical calculati ons demonstrate that the masses and decay constants are insensitive to the variation of temperature up to $T\\cong100 MeV$\, however after this poin t\, they start to fall altering the temperature. At deconfinement temperat ure\, the decay constants attain roughly to 45% of their vacuum values\, w hile the masses are diminished about 12% and 2.5% for $J/\\psi$ and $\\Up silon$ states\, respectively. The obtained results at zero temperature are in good consistency with the existing experimental data as well as predic tions of the other nonperturbative models. Considerable decreasing in the values of the decay constants can be considered as a sign of the quark glu on plasma phase transition.\n\nhttp://indico.cern.ch/contributionDisplay.p y?contribId=31&sessionId=8&confId=117804 LOCATION:Dogus University\, Istanbul\, Turkey URL:http://indico.cern.ch/contributionDisplay.py?contribId=31&sessionId=8& confId=117804 END:VEVENT BEGIN:VEVENT SUMMARY:PHIN Photo-Injector as the CLIC Drive Beam Source DTSTART;VALUE=DATE-TIME:20110624T140000Z DTEND;VALUE=DATE-TIME:20110624T142000Z DTSTAMP;VALUE=DATE-TIME:20130619T160527Z UID:indico-contribution-117804-30@cern.ch DESCRIPTION:Speakers: Dr. METE\, Oznur (CERN / EPFL)\nThe Compact Linear C ollider (CLIC) study proposes a multi-TeV\, high luminosity\, electron-pos itron linear collider in order to fulfill the current need for a lepton c ollider. The study has been started in the late 80s at CERN and currently is a joint effort with a collaboration of 40 institutes. An innovative sch eme of high peak RF power production for the high accelerating gradient ha s been proposed for CLIC. The so called "two-beam scheme" consists of two beams that are running parallel to each other. One of the beams is to be a ccelerated for the collision experiments and called "the main beam". The s econd beam of the CLIC scheme is "the drive beam" and will be employed for the power production. The quality of the main beam acceleration depends o n the stability of the power that is generated by the drive beam. Therefor e\, the optimization of the drive beam production with the proper time str ucture and within the required beam dynamics tolerances is one of the most important accelerator physics aspects of the project. \n\nCurrently in th e conceptual level\, the baseline design of the drive beam injector consis ts of a thermionic gun. This electron source has to be combined with a sub -harmonic bunching system in order to provide the required time structure of the drive beam. However\, a big disadvantage of this scheme is the para sitic satellite bunches that are produced due to the sub-harmonic bunching system. PHIN photoinjector has been raised as another option in order to replace the existing thermionic gun of CLIC test facility (CTF3) and to fo rm the bases of a source for the CLIC drive beam. The PHIN project is in t he framework of the European CARE (Coordinated Accelerator Research in Eur ope) program. \n\nIn this talk the highlights from the design and the comm issioning of the PHIN photoinjector will be presented.\n\nhttp://indico.ce rn.ch/contributionDisplay.py?contribId=30&sessionId=8&confId=117804 LOCATION:Dogus University\, Istanbul\, Turkey URL:http://indico.cern.ch/contributionDisplay.py?contribId=30&sessionId=8& confId=117804 END:VEVENT BEGIN:VEVENT SUMMARY:ATLAS TRT and its performance at LHC DTSTART;VALUE=DATE-TIME:20110623T110000Z DTEND;VALUE=DATE-TIME:20110623T112000Z DTSTAMP;VALUE=DATE-TIME:20130619T160527Z UID:indico-contribution-117804-51@cern.ch DESCRIPTION:Speakers: Dr. BINGUL\, Ahmet (Gaziantep U.)\nThe ATLAS Transit ion Radiation Tracker (TRT) is the outermost of the three sub-systems of t he ATLAS Inner Detector at the Large Hadron Collider at CERN. It consists of close to 300000 thin-wall drift tubes (straws) providing on average 30 two-dimensional space points with 0.12-0.15 mm resolution for charged part icle tracks with |eta| 0.5 GeV. Along with continuous tracking\, it provi des particle identification capability through the detection of transition radiation X-ray photons generated by high velocity particles in the many polymer fibers or films that fill the spaces between the straws. Custom-bu ilt analog and digital electronics is optimized to operate as luminosity i ncreases to the LHC design.

Rapid improvements in the calibration and alignment of the det ector allowed it to reach nearly the nominal performance in the timespan o f a few months. The tracking performance proved to be stable as the LHC lu minosity increased by five orders of magnitude during the 2010 proton run\ , while the performance was only slightly degraded in the extremely dense heavy ion collisions.

Te chnol.)\nThe scaling behavior of the v_2 at ultrarelativistic heavy ion co llisions is considered as a signal of collective behavior of the partons i n hot and/or dence hadronic matter [1-4]. The early results of CERN EMC [5 -6] and JINR on the effect of limiting fragmentation of nuclei [7-9] were might be also explained through the collective behavior of the partons in the medium with extreme density. The phenomenon could lead to formation of the partons / hadrons with extreme high energies due to which all/majo rity of partons in the group collectively could give their energies to sin gle (or a few) partons/hadrons. In this case the energy of the energetic partons could be limited mainly with the total energy of the collective pa rtonic system. Using the idea given above one can explain the source of th e cosmic particles in the energy domain greater than 10^15 eV. It is surm ised that such energetic partons could be formed in the center of the mass ive stars with density close to the Quantum Chromodynamic critical one\, transformed to the energetic hadron and were detected as high energy cosmi c particles [10].\n\n1.

Inside transve rse magnetic fields\, axions can be converted into x-rays\, which can be d etected by x-ray detectors. The expected signal in CAST is 1-10 keV range. Low noise and low background detectors are highly necessary to increase sensitivity of the experiment. Micro Mesh Gaseous Structure (micromegas) d etectors have been used in CAST since the beginning\, providing a good ene rgy and spatial resolution for CAST's needs. CAST has been intensely study ing micromegas detectors to develop new technologies\, decrease background levels\, increase stability and understand the nature of the background. While in 2003\, there was 1 micromegas\, 1 Time Projection Chamber (TPC) a nd 1 Charged Couple Device (CCD)\, improvements in micromegas detector enc ouraged CAST to increase the number to 3\, replacing TPC with 2 micromegas detectors. In some periods during CAST run\, a special phenomena called " Ultra low background" is observed\, where for a few days background rate d ecrease to ~1×10^{-7}s^{-1}cm^{-2}keV^{-1}. To investigate this\, simulat ions and shielding tests are being done at the Canfranc Underground Labora tory. If this low background is indeed not a systematic effect\, that can open new possibilities on rare event searches at ground.\n\nhttp://indico. cern.ch/contributionDisplay.py?contribId=57&sessionId=8&confId=117804 LOCATION:Dogus University\, Istanbul\, Turkey URL:http://indico.cern.ch/contributionDisplay.py?contribId=57&sessionId=8& confId=117804 END:VEVENT END:VCALENDAR
