Book Synopsis Charged Particle Multiplicity and Open Heavy Flavor Physics in Relativistic Heavy Ion Collisions at the LHC by : Yujiao Chen
Book excerpt: Furthermore, the pT dependence of the relative muon yields in Pb+Pb collisions to p+p colli- sions with the same center of mass collision energy per nucleon is presented by the nuclear modification factor RAA, which is defined as the ratio of a spectrum from heavy ion collisions to the same but scaled spectrum from nucleon-nucleon collisions . The observed RAA has little dependence on pT within the uncertainties quoted here. The results for RAA indicate a factor of about 3 suppression in the yield of muons in the most central (0-10%) collisions compared to the p+p collisions.
