Singlet Boson in Supersymmetric Model as a Mimic of the Standard Model Higgs at the LHC

TL;DR

This paper demonstrates that a gauge singlet scalar in a supersymmetric model can imitate the Standard Model Higgs boson at the LHC by coupling to heavy vector-like colored particles, producing similar signals across a range of masses.

Contribution

It introduces a mechanism where a singlet scalar mimics the SM Higgs at the LHC through specific couplings, expanding the understanding of Higgs-like signals in supersymmetric models.

Findings

Singlet scalar can produce SM Higgs-like signals at the LHC.

Coupling to heavy vector-like colored particles is key.

Mimicry occurs over a wide mass range.

Abstract

We show that the gauge singlet scalar boson in low-energy supersymmetric model may behave as the standard model (SM) Higgs boson if the singlet couples to (heavy) vector-like colored particles. In this case, the SM-Higgs-like signal at the LHC can be mimicked by the singlet production process for wide range of the singlet mass.
