Two- and Three-Body Decay Modes of SUSY Higgs Particles

Abstract

We summarize the dominant decay modes of the neutral and charged Higgs bosons in the Minimal Supersymmetric extension of the Standard Model. While two--body decays are in general dominating, the branching ratios for three--body decays of the heavy scalar, pseudoscalar and charged Higgs bosons can be large below the thresholds if top quarks, $W/Z$ bosons or heavy scalar bosons are involved. Analytical expressions have been derived for the partial decay widths and the physical implications of these decay modes are discussed.
