Searches for diboson resonances at CMS

TL;DR

This paper reports on a series of searches for heavy resonances decaying into various boson pairs using CMS data at 13 TeV, setting limits on models predicting new W', Z', and graviton particles.

Contribution

It provides comprehensive search results for multiple diboson resonance channels at the LHC, interpreting data within several theoretical models and establishing upper limits on their production cross sections.

Findings

No evidence for new resonances was observed.

Upper limits were set on the production cross sections of W', Z', and graviton models.

Results constrain parameters of composite-Higgs and extra-dimensional theories.

Abstract

A list of searches is presented for massive resonances decaying to WW, WZ, ZZ, WH, ZH and HH boson pairs in proton-proton collision data collected by the CMS experiment at the LHC. The data are taken at centre-of-mass energies of 13TeV, corresponding to respective integrated luminosities of 12.9/fb(ICHEP) and up to 35.9/fb. The results are interpreted in the context of heavy vector triplet and singlet models that mimic properties of composite-Higgs models predicting W' and Z' bosons decaying to WZ, WW, WH, and ZH bosons. A model with a bulk graviton that decays into WW and ZZ is also considered. Upper limits are set on the production cross section of the two models and no evidence is found for a signal.
