Leader of project: Prof. Dr. Dragan Popovic
The ATLAS experiment will explore the high energy frontier at the Large Hadron Collider at CERN, scheduled to start operation in 2007. There are good reasons to believe that some new phenomena, beyond the Standard Model, must exist over the accessible energy range (up to 14 TeV). Institute of Physics is a member of ATLAS Collaboration since 2003. Institute of Physics joined ATLAS making a hardware contribution in the shielding system. Shielding disks of the total weight 98 tons were produced by Lola Corporation, Zeleznik. HEP Laboratory, Institute of Physics, is involved in ATLAS research topics considering processes and phenomena predicted by the Standard Model and its Supersymmetric extensions. Physics Topics at IP Belgrade: * WW production and triple gauge-boson couplings * Higgs H/A search within MSSM model * SUSY search within mSUGRA model * Muon detection and reconstruction efficiency in SUSY environment * ATLAS Monte Carlo production in grid environment

At the European Laboratory for Particle Physics (CERN) in Geneva, a new particle accelerator, the Large Hadron Collider (LHC) is presently being constructed. In parallel to the accelerator two general purpose detectors, ATLAS and CMS, are constructed to investigate the proton proton collisions in the new energy domain and to study fundamental questions of particle physics such as the mechanism responsible for the spontaneous symmetry breaking in the Standard Model. ATLAS is designed as a general purpose detector, capable of running at the highest beam intensities and providing the means for two major goals to the physics studies at LHC: discovery potential for new physics and potential to do precision measurements of known objects. In collaboration with about 2000 physicists our group is involved in the ATLAS detector shield construction.Our group is also engaged in the studies of physics potentials of ATLAS experiment in searching for supersymmetric particles as well as in the studies of the capability for the precise measurements of the top quark mass and sensitivity limits for anomalous triple gauge boson couplings.
Nucleus-nucleus collisions at relativistic energies provide the information about properties and states of matter at the high temperatures and pressures. Among the various competing processes occurring we study experimentally the fission of the target residue that provides an excellent tool for exploring the latter stage of nuclear collisions.
Laboratory for High Energy Physics cooperates closely with the Faculty of Physics, University of Belgrade, Faculty of Physics and Mathematics, University of Podgorica and Faculty of Sciences, University of Kragujevac.
