Discrimination of the light CP-odd scalars between in the NMSSM and in the SLHM

TL;DR

This paper proposes a practical method to distinguish between the NMSSM and SLHM models by analyzing the decay patterns of light CP-odd scalars produced from the Higgs boson, highlighting their phenomenological differences.

Contribution

It introduces a new strategy based on decay rate ratios to differentiate the NMSSM from the SLHM in light CP-odd scalar phenomenology.

Findings

Decay rate ratios differ significantly between NMSSM and SLHM.

The proposed method effectively discriminates models using decay patterns.

Phenomenological behaviors of CP-odd scalars are model-dependent.

Abstract

The presence of the light CP-odd scalar boson predicted in the next-to-minimal supersymmetric model (NMSSM) and the simplest little Higgs model (SLHM) dramatically changes the phenomenology of the Higgs sector. We suggest a practical strategy to discriminate the underlying model of the CP-odd scalar boson produced in the decay of the standard model-like Higgs boson. We define the decay rate of "the non $b$-tagged jet pair" with which we compute the ratio of decay rates into lepton and jets. They show much different behaviors between the NMSSM and the SLHM.
