High Energy Physics with the CMS Detector

The CMS detector is the most complex and technologically advanced instrument up to date. It is made in the form of a cylinder composed of the barrel and two endcaps, each made of four different detector layers: Tracker, ECAL, HCAL and four rows of MUON chambers. The first three layers are embedded into the huge superconducting solenoid magnet making the detector compact and robust. Besides precise measurements of parameters that will enable us to elucidate the electroweak breaking mechanism, all four detector layers are designed to detect a wide range of particles and phenomena produced in high energy p-p collisions, allowing us to explore physics at the unprecedented LHC energy scale and providing the evidence of physics beyond the Standard model. The Serbian research Team from VINČA Institute and Faculty of Physics of the University of Belgrade is involved into the CMS experiment through three kinds of activities: 1. Design, construction, testing and installation of the ECAL Safety System (ESS); 2. Participation in physics analysis of: a) Standard model Higgs boson decay channel into two photons (H›??); b) Anomalous Triple Gauge Boson Couplings (Z??, ZZ?) in the di-boson channel: Z?; c) search for lepton events in the supersymmetry channel of squark and gluino; d) participation in DQM of the trigger system; 3. The engineering task related to design and 3D modeling of elements of the CMS detector during its construction and installation. First results are already published.
