Résumé

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]), Δκ_γ ([−0.044,0.063]), and Δg₁ ^Z ([−0.0087,0.024]). These limits are also translated into their effective field theory equivalents: c_WWW/Λ² ([−2.7,2.7] TeV⁻²), c_B/Λ² ([−14,17] TeV⁻²), and c_W/Λ² ([−2.0,5.7] TeV⁻²).
