Limit on $Br(b\to sg)$ in Two Higgs Doublet Models

Abstract

Using the recent CLEO measurement of $Br(b\to s\gamma )$, we find that the branching ratio of $b\to sg$ cannot be larger than $10\%$ in two Higgs doublet models. The small experimental value of $Br(b\to e\bar{\nu }X)$ can no longer be explained by charged Higgs boson effects.
