摘要：

The most general two Higgs doublet model potential without explicit CP violation depends on 10 real independent parameters. There are two different ways of restricting this potential to 7 independent parameters. This gives rise to two different potentials, V-(A) and V-(B). The phenomenology of the two models is different, because some trilinear and quartic Higgs couplings are different. As an illustration, we calculate the decay width of h(0) --> gamma gamma, where precisely due to the different trilinear couplings the loop of the charged Higgs boson gives different contributions. We also discuss the possibility for the existence of a light fermiophobic Higgs boson. [S0556-2821(99)04615-9].
