Study of Diboson Production at CMS (1110.2521v1)
Published 11 Oct 2011 in hep-ex
Abstract: I present an overview of the measurements of the di-boson (WW, WZ, ZZ, W\gamma, and Z\gamma) production cross sections in proton-proton collisions at \sqrt{s} = 7 TeV. The measurements are based on 36 pb-1 and 1.1 fb-1 of data collected with the CMS detector at the LHC in 2010 and 2011, respectively. The vector bosons W and Z are reconstructed in purely leptonic decays. The measured cross sections are compared with the Standard Model expectations calculated at next-to-leading order in perturbative QCD. Limits on anomalous triple gauge boson couplings are derived.
