Limits on direct detection of neutralino dark matter from b -> s gamma decays

Abstract

We analyze the rate of detection of minimal supersymmetric neutralino dark matter in germanium, sapphire and sodium iodide detectors, imposing cosmological and recent accelerator bounds including those from \bsg\ decay. We find, in contrast with several other recent analyses, that although the \bsg\ constraint reduces the number of viable models, models still remain where the counting rate in solid state detectors exceeds 10 kg${}^{-1}$ day${}^{-1}$.
