LHC Constraints on 3-3-1 Models

TL;DR

This paper uses ATLAS di-lepton data to set lower bounds on $Z'$ boson masses in 3-3-1 and $E_6$ models, extrapolates results to future collider energies, and reports vector and axial charges for these models, many of which are newly documented.

Contribution

It provides new lower mass bounds for $Z'$ bosons in 3-3-1 models, extrapolates constraints to future collider energies, and reports vector and axial charges previously unreported.

Findings

Lower mass bounds at 95% confidence level established.

Extrapolated bounds for 14 TeV, 30 TeV, and 100 TeV colliders.

Vector and axial charges for 3-3-1 $Z'$ models reported for the first time.

Abstract

The ATLAS detector data on di-lepton production is used in order to impose constraints on $Z^\prime$ boson masses associated with a variety of 3-3-1 and $E_6$ motivated $Z'$ models. Lower mass bounds for the different models are established at $95\%$ confidence level. Our numerical analysis is extrapolated up to 14~TeV, and further to 30~TeV and 100~TeV, for a broad range of luminosities. Some of our results can be compared with the ATLAS published bounds, being, for those cases, in fairly good agreement. We also report the vector and axial charges for all the 3-3-1-motivated $Z'$ models without exotic electric charges for leptons, known in the literature. To the best of our knowledge most of this charges were not reported before.
