Charged Higgs boson effects are not helicity suppressed in the decays [ital B][sup [minus]][r arrow][tau][bar [nu]], [mu][bar [nu]], and [ital e][bar [nu]], and could enhance or suppress these modes without violating lepton universality. The present limit of [ital B]([ital B][sup [minus]][r arrow][mu][bar [nu]])[lt]2.0[times]10[sup [minus]5] is more stringent than the measurement [ital B]([ital b][r arrow][tau][bar [nu]]+[ital X])=(4.20[sub [minus]0.68][sup +0.72][plus minus]0.46)%, while a factor of 2 improvement in the present limit of [ital B]([ital B][sup [minus]][r arrow][tau][bar [nu]])[lt]1.2% would be comparable. There is much room for discovery as one pushes the latter limit down to the standard model expectation of order 10[sup [minus]4]. A value below this may be explained without requiring [ital f][sub [ital B]][vert bar][ital V][sub [ital u][ital b]][vert bar] to be unduly small.
