Abstract

The constraints on the two Higgs doublet model from the new experimental bounds of $b\to s\gamma$ by CLEO and the latest published value of the top quark mass by CDF and D0 are reanalyzed with the effective Lagrangian covering the full QCD corrections from the energy scale of top quark to that of bottom. The reanalysis result shows that the constraints become more stringent than that of the earlier analysis, i.e. a bigger region of the parameter space of the model is ruled out.
