Higgs Bosons in the Next-to-Minimal Supersymmetric Standard Model at the LHC

TL;DR

This paper reviews distinctive properties of Higgs bosons in the NMSSM, highlighting features like higher masses, enhanced decay channels, and Higgs-to-Higgs decays to differentiate it from the MSSM at the LHC.

Contribution

It provides a comprehensive analysis of Higgs boson signatures in the NMSSM, emphasizing unique mass ranges, decay modes, and the presence of lighter singlet-like states.

Findings

Standard-Model-like Higgs above 140 GeV accompanied by a lighter singlet-like state

Enhanced branching fractions into two photons in certain NMSSM scenarios

Higgs-to-Higgs decays vary with production modes and decay channels

Abstract

We review possible properties of Higgs bosons in the NMSSM, which allow to discriminate this model from the MSSM: masses of mostly Standard-Model-like Higgs bosons at or above 140 GeV, or enhanced branching fractions into two photons, or Higgs-to-Higgs decays. In the case of a Standard-Model-like Higgs boson above 140 GeV, it is necessarily accompagnied by a lighter state with a large gauge singlet component. Examples for such scenarios are presented. Available studies on Higgs-to-Higgs decays are discussed according to the various Higgs production modes, light Higgs masses and decay channels.
