Present Bounds on New Neutral Vector Resonances from Electroweak Gauge Boson Pair Production at the LHC

TL;DR

This paper uses LHC data to set model-independent bounds on new neutral vector resonances predicted by extensions of the Standard Model, excluding masses up to 1-2.3 TeV based on W+W- pair production.

Contribution

It provides a framework for model-independent bounds on neutral vector resonances using LHC data, applicable to various theoretical models.

Findings

Excludes neutral vector resonances up to 1-2.3 TeV

Analyzes W+W- production data from ATLAS and CMS

Demonstrates extension of analysis to different models

Abstract

Several extensions of the Standard Model predict the existence of new neutral spin-1 resonances associated to the electroweak symmetry breaking sector. Using the data from ATLAS (with integrated luminosity of L=1.02 fb^{-1}) and CMS (with integrated luminosity of L=1.55 fb^{-1}) on the production of W+W- pairs through the process pp -> l^+ l^{\prime -} \sla{E}_T, we place model independent bounds on these new vector resonances masses, couplings and widths. Our analyses show that the present data excludes new neutral vector resonances with masses up to 1-2.3 TeV depending on their couplings and widths. We also demonstrate how to extend our analysis framework to different models working a specific example.
