Elementary Particle Physics
Experimental research in elementary particle physics with accelerators and colliders experiments CMS at the LHC; H1 at HERA-DESY, Hamburg; OPERA at CERN) and in astroparticles (neutrino telescope IceCube); grille de calcul intégré; instrumentation developments (data acquisition systems); node of the intensive computing grid (LHC GRID).
CMS experiment at the LHC: search for extra spatial dimensions
Detection and identification of the process quark + anti-quark -> e+ + e- with the CMS (Compact Muon Solenoid) detector at the CERN Large Hadron Collider (LHC). This process allows to test precisely the Standard Model and to search for new particles (Z') predicted by the Grand Unifying Theories (GUT) and the models introducing extra spatial dimensions. Study of the top quark properties: mass, cross section, search for new particles, b-quark physics.
