Özet
This Letter presents a search for new physics manifested as anomalous triple gauge boson couplings in W W and W Z 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]), Δ κ γ ([− 0.044, 0.063]), and Δ g 1 Z ([− 0.0087, 0.024]). These limits are also translated into their effective field theory equivalents: c W W W/Λ 2 ([− 2.7, 2.7] TeV− 2), c B/Λ 2 ([− 14, 17] TeV− 2), and c W/Λ 2 ([− 2.0, 5.7] TeV− 2).
