Nuclear modification factors from the CMS experiment
Abstract
We report the measurements of nuclear modification factors of the Z bosons, isolated photons and charged particles in sNN = 2.76 TeV PbPb collisions with the CMS detector. The nuclear modification factors are constructed by dividing the PbPb pT spectra, normalized to the number of binary collisions, by the pp references. No modifications are observed in isolated photon and Z boson production with respected to the pp references while large suppression is observed in the charged particles.
