The full CMS and ATLAS Run 2 datasets with time-integrated luminosity of 137 and 139
fb−1
in the diboson channels are used to probe benchmark models with extended gauge
sectors such as left-right symmetric (LR) and the sequential standard model (extended
gauge model, EGM), that predict the existence of neutral Z0
- and charged W0
- bosons
decaying to a pair of bosons ZH and WH in the semileptonic final state. These benchmark
models are used to interpret the results. Exclusion limits at the 95% C.L. on the Z
0 and W0
resonance production cross section times branching ratio to electroweak gauge boson pairs
in the resonance mass range between 1.0 and 5 TeV are here converted to constraints on Z-Z0
and W-W0 mixing parameters and masses. We present exclusion regions on the parameter
spaces of the Z
0 and W0 and show that the obtained exclusion regions are significantly
extended compared to those derived from the previous analysis performed with Tevatron
data as well as with the CMS and ATLAS data collected at 7 and 8 TeV in Run 1. The
reported limits are the most restrictive to date.
