Triple gauge coupling analysis using boosted W’s and Z’s

Abstract

We analyze the Large Hadron Collider potential to study triple couplings of the electroweak gauge bosons using their boosted hadronic decays. Deviations from Standard Model predictions spoil cancelations present in the Standard Model leading to the growth of the electroweak diboson production cross section at high center-of-mass energies. In this kinematical limit, W’s and Z’s are highly boosted, and consequently, their hadronic decays give rise to fat jets. Here, we show that the study of boosted hadronically decaying W and Z leads to limits on triple gauge couplings that are comparable to the ones originating from the leptonic decay channels.
