We give a more complete calculation of b → sλ decay in the two-Higgs doublet model, including leading log QCD corrections from mtopto MWin addition to corrections from MWto mb. The inclusive decay rate in the first model is found to be suppressed by 23% compared with the calculations without the QCD running from mtopto MW, and an enhancement up to 5% is found in calculations of the second model. More strict restrictions to the parameters of two-Higgs doublet model II are found. © 1995.
