Description

The production of W and Z bosons has been observed in pp collisions at a center-of-mass energy of 8 TeV using data collected in the CMS experiment. W events were selected containing an isolated, energetic electron or muon. Z events were 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 the W and Z signal yields and the extracted cross-sections at sqrt(s)=8 TeV, as well as the ratio of 8 TeV / 7 TeV cross sections.
