Abstract

The possibility to measure dimuons from Υ and J/Ψ families, hardjets And photons produced in ultra-relativistic heavy ion collisions at LHC energies have been investigated. The simulations were carried out for the CMS detector. A strong correlation between the transverse energy gathered in the calorimeters and event centrality is observed. The invariant mass spectrum for Pb-Pb events is presented and the signal to background ratios for Υ and J/Ψ masses are calculated. Expected statistics will be large enough to look for the correlations with centrality of events and transverse momentum of the resonance state. The jets and photons with E T > 100GeV will be measured with good efficiency and purity. γ-jet and Z-jet events give a good possibility to evaluate the energy losses of hard partons in dense matter.
