Electroweak spin-1 resonances in Composite Higgs models

Abstract

Composite Higgs models predict the existence of various bound states. Among these are spin-1 resonances. We investigate models containing ${\text{SU(2)}}_L\times {\text{SU(2)}}_R$ as part of the unbroken subgroup in the new strong sector. These models predict that there are two neutral and one charged spin-1 resonances mixing sizably with the SM vector bosons. As a consequence, these can be singly produced in Drell-Yan processes at the LHC. We explore their rich LHC phenomenology and show 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.
