Radiative corrections can produce substantial changes in the masses, production cross sections, and decay branching fractions of Higgs bosons in supersymmetric models, which can greatly modify their experimental detectability. We study variations in the expected event rates at pp supercolliders caused by radiative effects from the full one-loop effective potential in the minimal model, for the CP-even bosons h and H. We note that the masses of h, H, and the CP-odd boson A can simultaneously fall in the intermediate mass range M(Z) < m < 2M(Z) that is difficult to explore at hadron supercolliders. We calculate the one-loop corrections to the triple neutral-Higgs-boson couplings that enter into the h and H branching fractions. We evaluate the pp --> h(H) production cross sections at the Superconducting Super Collider energy, together with the principal h and H decay fractions, and compare them with standard-model results. We find that the h and H Higgs-boson signals in the gamma-gamma and l+l-l+l- decay channels are generally less favorable than for the standard-model Higgs-boson search, except in some special cases.
