Abstract

We study the Higgs sector of the Minimal Supersymmetric Standard Model, in the context of proton-proton collisions at LHC and SSC energies. We assume a relatively heavy supersymmetric particle spectrum, and include recent results on one-loop radiative corrections to Higgs-boson masses and couplings. We begin by discussing present and future constraints from the LEP experiments. We then compute branching ratios and total widths for the neutral ( $h, H, A$ ) and charged ( $H^{\pm}$ ) Higgs particles. We present total cross-sections and event rates for the important discovery channels at the LHC and SSC. Promising physics signatures are given by $h \to γ γ$ , $H \to γ γ$ or $Z^{*} Z^{*}$ or $τ^{+} τ^{-}$ , $A \to τ^{+} τ^{-}$ , and $t \to b H^{+}$ followed by $H^{+} \to τ^{+} ν_{τ}$ , which should allow for an almost complete coverage of the parameter space of the model.
