Description

In the Minimal Supersymmetric Standard Model, the possibility for the lightest CP-even Higgs boson to be lighter than Z-boson (as low as about 60 GeV) is, contrary to the usual belief, is not yet excluded by LEP2 data or any other existing experimental data. This Light Higgs boson scenario (LHS) is characterized by suppressed ZZh coupling and the decay branching ratio Br(h/A-> bb) as a result of generic supersymmetric loop corrections. Consequently, the (W+ H- h) coupling has to be large due to the sum rule of Higgs couplings to weak gauge bosons. We demonstrate that the associate neutral and charged Higgs boson production process, pp -> H+ h (A), can completely probe LHS at the CERN Large Hadron Collider and discuss additional reactions and potential o B-factories for complementary probe of the Light Higgs Scenario.
