TL;DR

This paper investigates a compactified higher-dimensional Higgs model's phenomenology at the LHC, focusing on the four-lepton channel, and explores its potential to mimic or deviate from the Standard Model Higgs sector.

Contribution

It introduces a compactified HEIDI model and analyzes its experimental signatures at the LHC, highlighting regions consistent with electroweak precision data.

Findings

Potential for the model to produce signals similar to the Standard Model Higgs

Identification of parameter space where deviations could be observed

Insights into the detectability of higher-dimensional Higgs sectors at the LHC

Abstract

Models with multi-scalar Higgs sectors inspired by a higher-dimensional setup are interesting alternatives to the Standard Model because, although they have a Higgs sector which gives mass to the W and Z gauge bosons as well as the SM fermions, this Higgs sector is potentially undiscoverable at the Large Hadron Collider or shows considerable deviations from the Standard Model Higgs sector. We investigate a compactified version of such models and study its phenomenology in the "golden" four-lepton channel at the LHC in areas of parameter space compatible with electroweak precision observables.
