Search for resonant WW and WZ production in ppbar collisions at ?s = 1.96 TeV

TL;DR

This paper reports a search for new resonant particles decaying into WW or WZ boson pairs in proton-antiproton collisions, setting mass exclusion limits for specific theoretical models.

Contribution

First search using Tevatron data to set limits on W' and graviton resonances in WW/WZ channels.

Findings

Excluded W' boson masses from 180 to 690 GeV.

Excluded graviton masses from 300 to 754 GeV.

Data consistent with standard model background.

Abstract

We search for resonant WW or WZ production using up to 5.4 fb-1 of integrated luminosity collected by the D0 experiment in Run II of the Fermilab Tevatron Collider. The data are consistent with the standard model background expectation, and we set limits on a resonance mass using the sequential standard model (SSM) W' boson and the Randall-Sundrum model graviton G as benchmarks. We exclude an SSM W' boson in the mass range 180 - 690 GeV and a Randall-Sundrum graviton in the range 300 - 754 GeV at 95% CL.
