This Letter presents a search for new physics manifested as anomalous triple gauge boson couplings in WW and WZ diboson production in protonâ 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 s=8 TeV with the CMS detector at the LHC, correspond to an integrated luminosity of 19 fbâ 1. No evidence for anomalous triple gauge couplings is found and the following 95% confidence level limits are set on their values: λ ([â 0.011,0.011]), Πκγ([â 0.044,0.063]), and Î g1Z([â 0.0087,0.024]). These limits are also translated into their effective field theory equivalents: cWWW/Î 2([â 2.7,2.7] TeVâ 2), cB/Î 2([â 14,17] TeVâ 2), and cW/Î 2([â 2.0,5.7] TeVâ 2).

Abstract

This Letter presents a search for new physics manifested as anomalous triple gauge boson couplings in WW and WZ diboson production in protonâ 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 s=8 TeV with the CMS detector at the LHC, correspond to an integrated luminosity of 19 fbâ 1. No evidence for anomalous triple gauge couplings is found and the following 95% confidence level limits are set on their values: λ ([â 0.011,0.011]), Πκγ([â 0.044,0.063]), and Î g1Z([â 0.0087,0.024]). These limits are also translated into their effective field theory equivalents: cWWW/Î 2([â 2.7,2.7] TeVâ 2), cB/Î 2([â 14,17] TeVâ 2), and cW/Î 2([â 2.0,5.7] TeVâ 2).
