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 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: ([-0.011, 0.011]), ([-0.044, 0.063]), and g Z 1 ([-0.0087, 0.024]). These limits are also translated into their effective field theory equivalents: -14, 17] TeV -2 ), and c W / 2 ([-2.0, 5.7] TeV -2 ).
