Search for resonant $WZ$ production in the fully leptonic final state at $13$ TeV with the CMS detector

A search for an electrically charged, narrow-width diboson ($WZ$) resonance in the fully leptonic final state using $137.65~fb^{−1}$ of data collected by the CMS experiment during the 2016- 2018 run period, at the LHC and a center of mass energy of $\sqrt(s) = 13$ TeV is presented. The search focuses on a channel where the resonance decays to a pair of standard model vector bosons: $W$ and $Z$. The $Z$ boson subsequently decays to a pair of leptons, either electrons ($e$) or muons ($\mu$). While the W boson decays to a lepton and a neutrino ($\nu$). As $\nu$ escapes undetected, the neutrino is reconstructed from the missing transverse momentum ($P^{miss}_{t}$) of the event. The analysis is based on a bump-hunt search strategy with background estimation based on stochastically generated simulation events. No significant excess of events is observed above the expected background from the Standard Model and limits are set on the production cross-section of the diboson resonance as a function of the resonance mass at 95% confidence level. Results are interpreted in the context of the Heavy Vector Triplet (HVT) framework.
