Some Decays of Neutral Higgs Bosons in the NMSSM

To solve the i problem of the Minimal Supersymmetric Standard Model (MSSM), a single field S is added to build the Next Minimal Supersymmetric Standard Model (NMSSM). Vacuum enlarged with non-zero vevs of the neutral-even CP is the combination of H, kid and S. In the NMSSM, the higgs sector is increased to 7 higgs (compared with 5 higgs in the MSSM), including three higgs which are even-CP h(1,2,3)( m(h1) < m(h2) < m(h3)), two higgs which are odd-CP a(1,2)(m(a1) < m(a2)) and a couple of charged higgs HI. The decays higgs into higgs is one of the remarkable new points of the NMSSM. In this paper we study some decays of neutral Higgs bosons. The numerical results are also presented together with evaluations.
