Many Light Higgs Bosons in the NMSSM
Radovan Dermisek, John F. Gunion

TL;DR
This paper explores the NMSSM with light Higgs bosons, highlighting unique decay channels and experimental signatures that could be detected at LEP, Tevatron, and B factories, expanding the search for new physics beyond the Standard Model.
Contribution
It identifies novel light Higgs decay modes and production channels in the NMSSM that have been overlooked or are poorly constrained by existing experiments.
Findings
Light CP-odd Higgs boson can evade current experimental limits.
New decay channels like $ ext{H}_i o a_i a_i$ and $ ext{H}^ ext{±} o W^{ ext{(star)}} a_i$ are viable.
Potential signals at LEP, Tevatron, and B factories for these light Higgs states.
Abstract
The next-to-minimal supersymmetric model with a light doublet-like CP-odd Higgs boson and small can satisfy all experimental limits on Higgs bosons even with light superpartners. In these scenarios, the two lightest CP-even Higgs bosons, and , and the charged Higgs boson, , can all be light enough to be produced at LEP and yet have decays that have not been looked for or are poorly constrained by existing collider experiments. The channel (where is the lightest CP-odd boson and has mass below ) with or is still awaiting LEP constraints for or , respectively. LEP data may also contain events where is the dominant decay, a channel that was never examined. Decays of the charged Higgs bosons are often dominated by with…
