Abstract
In this paper, we present the branching ratios of the two lightest CP-even Higgses, h(1) and h(2), and the lightest CP-odd Higgs, a(1), in the context of the Next-to-Minimal Supersymmetric Standard Model (NMSSM). We find that for some regions of the parameter space, the branching fractions of a(1) into the lightest charginos (a(1) -> chi(+)(1)chi(-)(1)) and neutralinos (a(1) -> chi(0)(1)chi(0)(1)) are larger than 50%, and can reach a 100% level in the latter case. Furthermore, the branching ratio of the h(2) -> a(1)a(1) can be equal to unity for all h(2) masses when it is a pure singlet. The above unusual channels are hallmarks of the existence of the NMSSM.
