Can $b\to s{\hat{I}}^3$ Close the Supersymmetric Higgs Production Window?

Abstract

We show that the present limit from CLEO on the inclusive decay $b\to s{\hat{I}}^3$ provides strong constraints on the parameters of the charged Higgs sector in two-Higgs-Doublet-Models. Only a slight improvement in the experimental bound will exclude the region in the Supersymmetric Higgs parameter space which is inaccessible to collider searches.
