Search for anomalous triple gauge couplings in WW and WZ production in lepton + jet events in proton-proton collisions at $\sqrt{s}=$ 13 TeV

Abstract

A search is presented for three additional operators that would lead to anomalous WW$\gamma$ 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$\nu$ or $\mu \nu$, 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 $<$ $c_{\mathrm{WWW}}/{\Lambda }^2$ $<$ 1.59 TeV${}^{-2}$, $-$2.00 $<$ $c_{\mathrm{W}}/{\Lambda }^2$ $<$ 2.65 TeV${}^{-2}$, and $-$8.78 $<$ $c_{\mathrm{B}}/{\Lambda }^2$ $<$ 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.
