Electroweak Precision Measurements in Diboson Production at CMS (2203.08863v1)
Published 15 Mar 2022 in hep-ex and hep-ph
Abstract: In this contribution, I have outlined recent precision measurements of the standard model (SM) multiboson production at CMS. A study of diboson production at 5 TeV constitutes an important probe of the SM at a new energy, and the data favour NNLO predictions obtained by MATRIX. A study of WZ production at 13 TeV constitutes the most comprehensive study of WZ production to date, containing inclusive and differential cross section measurements, charge asymmetry measurements, constraints on the LHC proton parton distribution functions, and constraints on anomalous values of the WWZ trilinear gauge coupling. No evidence for new physics is found, and all the results favour SM predictions calculated at NNLO using MATRIX.
