  • The possibilities of seeking the Higgs boson in the new generation of/ital e//sup +//ital e/minus// colliders are investigated in the framework of supersymmetrytheory. It is shown that at initial-beam energies (/ital s/)/sup 1/2/ /approx gt/1 TeVthe total cross section of the process /ital e//sup +//ital e/minus///r arrow//mu/tilde ///mu/tilde ///ital H/ isapproximately two orders of magnitude greater than the cross section of thestandard process /ital e//sup +//ital e/minus///r arrow//mu+//mu/minus///ital H/. It is found that suchpolarization characteristics of the processes under consideration as the spinasymmetry and the polarization of one of the initial beams differ in sign, andthis can serve as amore » good test for the identification of supersymmetry.« less
  • We discuss the production and two-photon decay of the lightest Higgs boson ({ital h}{sup 0}) of the minimal supersymmetric standard model at the CERN Large Hadron Collider (LHC). Since the observability of the signal is quite model dependent, we conduct a thorough scan of the parameter space of minimal supersymmetry, including experimental and theoretical constraints. If kinematically allowed, supersymmetric decay modes of {ital h}{sup 0} may be important, and can even dominate all others. The coupling of {ital h}{sup 0} to {ital bb}{vert_bar} can be different from that of a standard model Higgs boson; this can diminish (or enhance, butmore » only if tan{Beta} is very large) the {ital h}{sup 0}{implies}{gamma}{gamma} signal. We emphasize the importance of a full treatment of radiative corrections in the Higgs sector for obtaining the {ital h}{sup 0}{ital b}{ital b}{vert_bar} coupling. If supersymmetric particles are not too heavy, their contributions in loops can either enhance or suppress both the production cross section and the {ital h}{sup 0}{implies}{gamma}{gamma} branching fraction. We discuss the relative importance of these factors in the context of various scenarios for the discovery of supersymmetry. Even if {ital h}{sup 0} is not detected at the LHC, {ital h}{sup 0} may still exist in its expected mass region. {copyright} {ital 1995 The American Physical Society.}« less
  • We quantify the extent to which naturalness is lost as experimental lower bounds on the Higgs boson mass increase, and we compute the natural upper bound on the lightest supersymmetric Higgs boson mass. We find that it would be unnatural for the mass of the lightest supersymmetric Higgs boson to saturate its maximal upper bound. In the absence of significant fine-tuning, the lightest Higgs boson mass should lie below 120 GeV, and in the most natural cases it should be lighter than 108 GeV. For modest tan{beta}, these bounds are significantly lower. Our results imply that a failure to observemore » a light Higgs boson in experiments previous to the CERN LHC becoming operational could provide a serious challenge to the principal motivation for weak-scale supersymmetry. {copyright} {ital 1997} {ital The American Physical Society}« less
