Search for anomalous couplings in boosted production in proton–proton collisions at
Here, 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 √s = 8 TeV 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 Δg1Z ([–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).
