Charged Higgs mass bound from the process in the minimal supergravity
The constraint on the mass of the charged Higgs boson from the recent
measurement of the inclusive 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
(). For , the bound exceeds 400 GeV when the ratio of two Higgs
vacuum expectation values () is larger than 10. No strong bound is
obtained for due to cancellations between charged Higgs and
supersymmetric particle contributions.Comment: Talk given by Toru Goto at Yukawa International Seminar '95: From the
