Some properties of the Higgs sector of the Next-to Minimal SuperSymmetric Model

TL;DR

This paper explores the Higgs sector of the NMSSM, analyzing Higgs boson masses and couplings, and compares it to the MSSM to understand differences and parameter constraints.

Contribution

It provides a detailed analysis of the Higgs sector in the NMSSM, including mass spectra, couplings, and the transition to the MSSM limit, which is a novel extension of prior models.

Findings

Higgs boson masses vary with model parameters

Couplings differ between NMSSM and MSSM scenarios

Constraints on parameters restrict Higgs sector properties

Abstract

The problems of the standard model are briefly reviewed and the motivations for introducing supersymmetry are discussed. Two realistic supersymmetric models; the Minimal SuperSymmetric Model, MSSM, and its proposed extension NMSSM are introduced briefly and then some details of the Higgs sector of NMSSM are stated and some constraints on parameters are described. I then explore the Higgs boson masses and couplings for some interesting scenarios, including a few different ways of taking the limit where NMSSM reduces to MSSM.
