Implications for Supersymmetric Dark Matter Detection from Radiative $b$ Decays

Abstract

We point out that combinations of parameters that predict large counting rates in experiments searching for supersymmetric dark matter often tend to predict a very large branching ratio for the inclusive decay \bsg. The recent measurement of this branching ratio, therefore, indicates that searches for supersymmetric dark matter might be even more difficult than previously anticipated.

12 pp + 5 uuencoded PS figures. The new upper and lower bounds on the $\br(\bsg)$ coming from the recent measurement by the CLEO Collaboration are implemented: the results are qualitatively unchanged.
