- Low-Mass Higgs Bosons in the NMSSM and Their LHC Implications
- Time: 2:15 pm

- Abstract: We study the Higgs sector of the Next to Minimal Supersymmetric Standard Model (NMSSM) in light of the discovery of the SM-like Higgs boson at the LHC. We perform a broad scan over the NMSSM parameter space and identify the regions that are consistent with current Higgs search results at colliders. In contrast to the commonly studied ``decoupling'' scenario in the literature where the MSSM CP-odd Higgs boson mass is large mA>>mZ, we pay particular attention to the light Higgs states in the case when mA ~ mZ. The SM-like Higgs boson could be either the lightest CP-even scalar or the second lightest CP-even scalar. These NMSSM parameter regions have unique properties and offer rich phenomenology. We evaluate the production and decay of the Higgs bosons in this model and comment on further searches at the LHC to probe the Higgs sector of the NMSSM.
