摘要
We study the supersymmetry parameter region excluded if no Higgs is found at LEP, and the region allowed if a Higgs boson is found at LEP. We describe the full seven parameter structure of the Higgs sector. When supersymmetry phases are included, tan beta > 2 is always allowed, and the lower limit on M-H1 if no signal is found is about 20% lower than in the Standard Model and about 10% lower than in the MSSM with phases set to 0, pi.
