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 View the MathML source with the CMS detector at the LHC, correspond to an integrated luminosity of 19 fb−1. No evidence for anomalous triple gauge couplings is found and the following 95% confidence level limits are set on their values: λ ([−0.011,0.011]), Δκγ ([−0.044,0.063]), and View the MathML source ([−0.0087,0.024]). These limits are also translated into their effective field theory equivalents: cWWW/Λ2 ([−2.7,2.7] TeV−2), cB/Λ2 ([−14,17] TeV−2), and cW/Λ2 ([−2.0,5.7] TeV−2).

Abstract
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 View the MathML source with the CMS detector at the LHC, correspond to an integrated luminosity of 19 fb−1. No evidence for anomalous triple gauge couplings is found and the following 95% confidence level limits are set on their values: λ ([−0.011,0.011]), Δκγ ([−0.044,0.063]), and View the MathML source ([−0.0087,0.024]). These limits are also translated into their effective field theory equivalents: cWWW/Λ2 ([−2.7,2.7] TeV−2), cB/Λ2 ([−14,17] TeV−2), and cW/Λ2 ([−2.0,5.7] TeV−2).File | Dimensione | Formato | |
