- 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 Zboson whose decay products are merged into a single reconstructed jet. The data, collected at root s= 8TeVwith 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: lambda([-0.011, 0.011]), Delta(kappa gamma)([-0.044, 0.063]), and Delta g(1)(Z)([-0.0087, 0.024]). These limits are also translated into their effective field theory equivalents: c(WWW)/Lambda(2)([- 2.7, 2.7] TeV-2), c(B)/Lambda(2)([-14, 17] TeV-2), and cW/Lambda(2)([- 2.0, 5.7] TeV-2).
