Hard Probes in Heavy Ion Collisions with CMS

Heavy Ion collisions at LHC energies allow studies of high density QCD medium in kinematic ranges where vacuum reference is well understood and reproduced with perturbative calculations. High transverse momentum particles from the medium provide information on the amount of energy loss they suffered in the medium, which is known as "jet quenching". Using the capabilities of the CMS detector, the analyses of jets and various types of correlations between reconstructed jets and hadrons provide a detailed picture of this mechanism.
