Description

The production of W and Z bosons is studied in pp collisions at a center-of-mass energy of 8 TeV using data collected in the CMS experiment. W events are selected containing an isolated, energetic electron or muon. Z events are selected containing a pair of isolated, energetic electrons or muons. Data-driven methods are used to estimate reconstruction and triggering efficiencies, and well as the main backgrounds. We present recent results on W/Z production cross sections, discuss the measurements of the lepton charge asymmetry in W events, forward-backward asymmetry in the Drell-Yan process.
