Phenomenology of electroweak spin-1 resonances

TL;DR

This paper studies composite Higgs models predicting new electroweak spin-1 resonances that could be produced at the LHC, with masses as low as 1.5 TeV, consistent with current data.

Contribution

It analyzes the phenomenology of electroweak spin-1 resonances in composite Higgs models with specific global symmetries, highlighting their potential observability at the LHC.

Findings

Two neutral and one charged spin-1 resonances predicted

Resonances can have masses as low as 1.5 TeV and still be consistent with LHC data

Resonances can be singly produced at the LHC

Abstract

Composite Higgs models with a fermionic UV completion predict the existence of various bound states. We investigate models containing SU(2)$_L\times$SU(2)$_R$ as part of the unbroken global subgroup in the new strong sector. These models predict that there are two neutral and one charged spin-1 resonances mixing seizable with the SM vector bosons. These can be singly produced at the LHC. We explore their LHC phenomenology and demonstrate that there are still viable scenarios consistent with existing LHC data where the masses of these states can be as low as about 1.5 TeV.
