Abstract
Charged Higgs boson effects are not helicity suppressed in the decays B-», », and e», and could enhance or suppress these modes without violating lepton universality. The present limit of B(B-»)<2. 0×10-5 is more stringent than the measurement B(b»+X)=(4.20-0.68+0. 720.46)%, while a factor of 2 improvement in the present limit of B(B-»)<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 10-4. A value below this may be explained without requiring fB|Vub| to be unduly small. © 1993 The American Physical Society.
