Abstract

We have previously proposed a light pseudoscalar Higgs boson in the next-to-minimal supersymmetric standard model (NMSSM), the A 1 0, as a candidate to explain the HyperCP observations in Σ ++μ -. In this paper we calculate the rates for several other rare decay modes that can help confirm or refute this hypothesis. The first modes we evaluate are K L ππA 1 0, which are interesting because they are under study by the KTeV Collaboration. We next turn to η ππA 1 0, which are interesting because they are independent of the details of the flavor-changing sector of the NMSSM and may be accessible at DAΦNE. For completeness, we also evaluate Ω - Ξ -A 1 0.
