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 Wboson that decays leptonically and a Wor Zboson whose decay products are merged into a single reconstructed jet. The data, collected at √s=8TeVwith the CMS detector at the LHC, correspond to an integrated luminosity of 19fb−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 ΔgZ1([−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 Wboson that decays leptonically and a Wor Zboson whose decay products are merged into a single reconstructed jet. The data, collected at √s=8TeVwith the CMS detector at the LHC, correspond to an integrated luminosity of 19fb−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 ΔgZ1([−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).
