Abstract

We report on recent measurements of W and Z boson production at CMS. These include measurements of inclusive and differential W and Z boson production cross sections at $\sqrt{s}$ = 8 and 13 TeV, measurements of the angular coefficients of Z boson production, forward-backward asymmetry of Z/$\gamma^{*}$ events, and W charge asymmetry at $\sqrt{s}$ = 8 TeV. These measurements can be used to improve PDFs and refine QCD calculations of weak boson production processes. In addition, a W-like mass measurement using Z boson events has been performed to probe the experimental uncertainties expected for a W mass measurement at $\sqrt{s}$ = 7 TeV.
