Abstract

We calculate the decay rate for inclusive BτνXB \rightarrow {\tau}{\nu}X decays in a two Higgs doublet model using heavy quark expansion and operator product expansion. Combined with the recent measurement of Br(B\raτνXB \ra \tau \nu X), we find a limit tanβ<0.58mH/\mboxGeV\tan \beta < 0.58 m_H/\mbox{GeV} at 90\%\ C.L..
