| Search for anomalous couplings in semileptonic WW and WZ decays at $\sqrt{s} = $ 13 TeV | ||

| April 2019 | ||
| Abstract: In this search additional operators that would lead to anomalous WW$\gamma$ or WWZ couplings are constrained by studying events with one W boson decaying to $\mathrm{e}\nu$ or $\mu\nu$, and one W or Z boson decaying hadronically, reconstructed as a single massive large-radius jet. The search uses a data set of proton-proton collisions with a centre-of-mass energy of 13 TeV as recorded by the CMS experiment at the CERN LHC in the year 2016, corresponding to an integrated luminosity of 35.9 fb$^{-1}$. Using the reconstructed diboson invariant mass, 95% confidence intervals are derived for the anomalous coupling parameters of $-1.58 < c_{\mathrm{W}\mathrm{W}\mathrm{W}}/\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. | ||
