Alexander Mamonov (Russian Federal Nuclear Center (RU))20/11/2012, 10:30Status and performance of the experimentsWe report on the development of a software simulator of the detector control system for the ALICE Photon Spectrometer (PHOS). PHOS is an electromagnetic calorimeter, part of the ALICE experiment installed at the CERN Large Hadron Collider (LHC). The simulator was design and developed based on the experience acquired during the first years of operation of the detector, from 2009 to 2012. It...Go to contribution page

Daria Savrina (M.V. Lomonosov Moscow State University (RU))20/11/2012, 11:20Status and performance of the experimentsThe LHCb experiment is purposed to study the properties of the beauty and charmed particles decays. In such decays the search for the physics beyond the Standard Model is performed in an indirect way, as one expects contribution from non-standard particles and forces to become visible through the branching fractions of the rare decays, CP-asymmetries and many other observables. The LHCb...Go to contribution page

Oleg Solovyanov (Institute for High Energy Physics (RU))20/11/2012, 12:00Status and performance of the experimentsAfter the successful data taking year of 2011 at 7 TeV, since March of 2012 the ATLAS experiment at LHC is collecting data with colliding proton beams at the previously unparalleled centre of mass energy of 8 TeV. A challenging task was to cope with the augmented event rates due to the increased luminosity delivered by the collider and large pileup conditions. A status of the ATLAS detector is...Go to contribution page

Meanwhile, plans are actively advancing for a series of upgrades, culminating roughly 10 years from now in the high luminosity LHC (HL-LHC) project, delivering of order five times the LHC nominal instantaneous luminosity along with luminosity levelling....Go to contribution page

Prof. Valery Telnov (Budker INP, Novosibirsk, Russia)21/11/2012, 09:00LEP3 Higgs factoryParticle loss due to the emission of single energetic beamstrahlung photons is shown to impose a fundamental limit on storage ring luminosities at energies more than 2E~140 GeV for head-on collisions and 2E~40 GeV for crab-waist collisions. Above these thresholds the suppression factor due to beamstrahlung scales as 1/E^4/3 and for a fixed power of synchrotron radiation L \propto R/E^13/3. ...Go to contribution page

m Koratzinos (University of Geneva)21/11/2012, 09:30LEP3 Higgs factoryThe discovery of X(125) at CERN, which looks increasingly likely to be the long-awaited Higgs boson, opens the debate of which type of machine would serve best as a Higgs factory. LEP3 is a low-cost, high-luminosity circular e+e- collider operating near the Higgs production optimal centre-of-mass energy of 240GeV. We will briefly discuss what accuracies on Higgs observables are necessary to...Go to contribution page

Dr Mirko Pojer (CERN)22/11/2012, 09:30Status and plans of LHC machineIn three years of operation, the LHC has delivered a total of more than 25 fb-1 of integrated luminosity, providing collisions at 7 and 8 TeV c.o.m. The reasons for this tremendous success will be underlined. At the beginning of next year, the machine will be stopped for about 20 months, at the end of which the energy, and therefore the potential for discoveries, will be increased.

Prof. Anatoly Petrukhin (Moscow State Engineering Physics Institute (RU))22/11/2012, 10:00Searches for Phenomena beyond the Standard ModelIn cosmic ray experiments, the particles with energies (10^15 – 10^19) eV are investigated. This interval corresponds to (1.4 – 140) TeV in the center-of-mass system, which is 10 times higher than maximum LHC energy. Many unusual results in cosmic ray experiments in this energy interval were observed, which cannot be explained in frame of existing theoretical models and approaches.
