Abstract:
A search is presented for three additional operators that would lead to anomalous WW γ or WWZ couplings with respect to those in the standard model. They are constrained by studying events with two vector bosons; a W boson decaying to e ν or μν , and a W or Z boson decaying hadronically, reconstructed as a single, massive, large- radius jet. The search uses a data set of proton-proton collisions at a centre-of-mass energy of 13 TeV, recorded by the CMS experiment at the CERN LHC in 2016, and corresponding to an integrated luminosity of 35.9 fb − 1 . Using the reconstructed diboson invariant mass, 95% confidence intervals are obtained for the anomalous coupling parameters of − 1 . 58 〈 c WWW / Λ 2 〈 1 . 59 TeV − 2 , − 2 . 00 〈 c W / Λ 2 〈 2 . 65 TeV − 2 , and − 8 . 78 〈 c B / Λ 2 〈 8 . 54 TeV − 2 , in agreement with standard model expectations of zero for each parameter. These are the strictest bounds on these parameters to date.
