Diboson resonant production in non-custodial composite Higgs models

TL;DR

This paper demonstrates that the observed diboson excess can be explained by non-custodial composite Higgs models, showing compatibility with various experimental constraints and identifying viable parameter space.

Contribution

It provides a model-based explanation for the diboson excess and analyzes the parameter space where this explanation remains consistent with other experimental data.

Findings

The diboson excess can be explained by s-channel exchange of massive vector bosons.

A compatible parameter space exists balancing the excess with electroweak and collider constraints.

The model remains consistent with dilepton, dijet, and top pair production data.

Abstract

We show that the recently reported excess in resonant diboson production can be explained in the context of non-custodial composite Higgs models. Dibosons are generated via the s-channel exchange of massive vector bosons present in these models. We discuss the compatibility of the signal excess with other diboson experimental searches. We also discuss the tension between diboson production and other experimental tests of the model that include electroweak precision data, dilepton, dijet and top pair production and show that there is a region of parameter space in which they are all compatible with the excess.
