Search for Anomalous Couplings in Boosted $\mathrm{ WW/WZ }\to\ell\nu\mathrm{ Q \bar{q} }$ Production in Proton-proton Collisions at $\sqrt{s}

This Letter presents a search for new physics manifested as anomalous triple gauge boson couplings in WW and WZ diboson production in proton-proton collisions. The search is performed using events containing a W boson that decays leptonically and a W or Z boson whose decay products are merged into a single reconstructed jet. The data, collected at sqrt(s) =8 TeV with the CMS detector at the LHC, correspond to an integrated luminosity of 19 inverse femtobarns. No evidence for anomalous triple gauge couplings is found and the following 95% confidence level limits are set on their values: lambda ([-0.011,0.011]), Delta kappa[gamma] ([-0.044,0.063]), and Delta g[1,Z] ([-0.0087,0.024]). These limits are also translated into their effective field theory equivalents: c[WWW]/ Lambda^2, ([-2.7,2.7] TeV^{-2}), c[B]/ Lambda^2, ([-14,17] TeV^{-2}), and c[W]/ Lambda^2, ([-2.0,5.7] TeV^{-2}).
