Overview of experimental results in Pb-Pb collisions at √s NN = 2.76 TeV by the CMS Collaboration

Abstract

The CMS experiment at the LHC is a general-purpose apparatus with a set of large acceptance and high granularity detectors for hadrons, electrons, photons and muons, providing unique capabilities for both proton–proton and ion–ion collisions. The data collected during the November 2010 Pb–Pb run at \sqrt{s_{{\mathrm{NN}}}} = 2.76 TeV were analyzed and multiple measurements of the properties of the hot and dense matter were obtained. Global event properties, detailed study of jet production and jet properties, isolated photons, quarkonia and weak bosons were measured and compared to pp data and Monte Carlo simulations.
