Updated constraints on heavy resonances using the RUN 2 data at LHC

Abstract

The full ATLAS and CMS Run 2 data set at the Large Hadron Collider (LHC) with time-integrated luminosity of 139 fb−1 and 137 fb−1, respectively, in the diboson channel is used to probe benchmark models with extended gauge sectors: the E6-motivated Grand Unification models, the left-right symmetric LR and the sequential standard model. These all predict neutral Z′ and charged W′ vector bosons, decaying into fermion or electroweak gauge boson pairs. We present constraints on the parameter space of the Z′ and W′ and compare them to those obtained from the previous analyses performed with LHC data collected at 7 and 8 TeV in Run 1 as well as at 13 TeV in Run 2 at time-integrated luminosity of 36.1 fb−1.
