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

The branching ratios and supercollider cross sections of the two CP-even Higgs scalars h⁰ and H⁰ of the minimal supersymmetric model (MSSM) are computed (including the effects of leading log radiative corrections). The "gold-plated" Higgs-boson decay into ZZ→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 h⁰ or H⁰ 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 h⁰ and H⁰ is briefly considered.
