摘要：

The constraint on the mass of the charged Higgs boson from the recent measurement of the inclusive b --> s gamma decay is studied in a framework of the minimal supergravity. It is shown that the lower bound for the charged Higgs mass crucially depends on the sign of the higgsino mass parameter (mu). For mu < 0, the bound exceeds 400 GeV when the ratio of two Higgs vacuum expectation values (tan beta) is larger than 10. No strong bound is obtained for mu > 0 due to cancellations between charged Higgs and supersymmetric particle contributions.
