A 4D Composite Higgs Model: Testing its Scalar Sector at the LHC

TL;DR

This paper tests a 4D Composite Higgs Model against LHC data, deriving its particle spectrum and performing a fit to assess its consistency with experimental observations.

Contribution

It provides a comprehensive derivation of the 4DCHM particle spectrum and implements it in computational tools for phenomenological analysis, including a fit to LHC data.

Findings

The model's spectrum is compatible with current LHC data.

Several parameter configurations satisfy experimental constraints.

The fit quantifies the model's overall consistency with observations.

Abstract

We explain the current Large Hadron Collider (LHC) data pointing to the discovery of a neutral Higgs boson in the context of a 4-Dimensional Composite Higgs Model (4DCHM). The full particle spectrum of this scenario is derived without any approximation and implemented in automated computational tools to enable fast phenomenological investigation. Several parameter configurations compliant with experimental constraints are presented and discussed. A $\chi^2$ fit to the LHC data quantifying the consistency of the 4DCHM as a whole with experimental evidence is finally performed.
