Search for massive resonances decaying into WW, WZ or ZZ bosons in proton-proton collisions at sqrt(s) = 13 TeV

TL;DR

This paper reports a search for new heavy resonances decaying into WW, WZ, or ZZ bosons in proton-proton collisions at 13 TeV, setting limits on models predicting such particles, with no significant signals found.

Contribution

First search for narrow-width spin-2 resonances at 13 TeV and combined analysis of multiple final states for heavy vector boson resonances.

Findings

No significant excess over the standard model background.

Set exclusion limits on cross sections and masses of hypothetical resonances.

First to analyze narrow-width spin-2 resonances at this energy.

Abstract

A search is presented for new massive resonances decaying to WW, WZ or ZZ bosons in l nu quark anti-quark and quark anti-quark quark anti-quark final states. Results are based on data corresponding to an integrated luminosity of 2.3-2.7 inverse femtobarns recorded in proton-proton collisions at sqrt(s) = 13 TeV with the CMS detector at the LHC. Decays of spin-1 and spin-2 resonances into two vector bosons are sought in the mass range 0.6-4.0 TeV. No significant excess over the standard model background is observed. Combining the results of the l nu quark anti-quark and quark anti-quark quark anti-quark final states, cross section and mass exclusion limits are set for models that predict heavy spin-1 and spin-2 resonances. This is the first search for a narrow-width spin-2 resonance at sqrt(s) = 13 TeV.
