Searching forCP-even Higgs bosons of the minimal supersymmetric model at hadron supercolliders

The branching ratios and supercollider cross sections of the two $\mathrm{CP}$-even Higgs scalars $h^0$ and $H^0$ of the minimal supersymmetric model (MSSM) are computed (including the effects of leading log radiative corrections). The "gold-plated" Higgs-boson decay into $\mathrm{ZZ}\to l^{+}{l}^{-}{l}^{+}{l}^{-}$ is analyzed at the CERN Large Hadron Collider and Superconducting Super Collider, and the regions of MSSM Higgs sector parameter space where the $h^0$ or $H^0$ can be detected in this mode are delineated. The prospects for Higgs-boson detection as a function of the detector resolution are discussed. The viability of other decay modes for detecting the $h^0$ and $H^0$ is briefly considered.
