Abstract

Measurements are presented of W and Z production in proton-proton collisions. Fiducial cross sections are reported based on a data sample corresponding to an integrated luminosity of 19.4 fb. collected with the CMS detector at a center-of-mass energy of 8 TeV. Signal is identi ed through the W!`and Z!``decay modes, where`is a muon or an electron. The production of W and Z, measured with signi cances of 2.6 and 5.9 standard deviations, respectively, is consistent with standard model predictions. In addition, limits on anomalous quartic gauge couplings in W production are determined in the context of a dimension-8 e ective eld theory.
