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$$^{-1}$. No evidence for anomalous triple gauge couplings is found and the following 95% confidence level limits are set on their values: λ ([-0.011,0.011]), Δ$κ$$_{Y}$ ([-0.044,0.063]) and Δg$\substack{Z\\I}$([-0.0087,0.024]). These limits are also translated into their effective field theory equivalents: c$_{www}$/Δ² ([-2.7, 2.7] TeV$^{-2}$, c$_{B}$/Δ² ([-14,17] TeV$^{-2}$, and $c$$_{W}$/Δ² ([-2.0,5.7] TeV$^{-2}$).
