LHC physics of extra gauge bosons in the 4D Composite Higgs Model

TL;DR

This paper investigates how extra gauge bosons predicted by a 4D Composite Higgs Model could be detected at the LHC through Drell-Yan processes, highlighting potential experimental signatures of new physics.

Contribution

It provides a detailed phenomenological analysis of neutral and charged current processes in a 4D Composite Higgs framework, including the impact of extra fermions and the distinguishability of multiple neutral resonances.

Findings

Multiple neutral resonances can be distinguished in invariant mass distributions.

Extra fermions influence the event rates and resonance signatures.

Certain parameter regions allow for experimental detection of these new gauge bosons.

Abstract

We study the phenomenology of both the Neutral Current (NC) and Charged Current (CC) Drell-Yan (DY) processes at the Large Hadron Collider (LHC) within a 4 Dimensional realization of a Composite Higgs model with partial compositness by estimating the integrated and differential event rates and taking into account the possible impact of the extra fermions present in the spectrum. We show that, in certain regions of the parameters space, the multiple neutral resonances present in the model can be distinguishable and experimentally accessible in the invariant or transverse mass distributions.
