Abstract

We present preliminary results on b → s γ from the CLEO experiment. An updated result on the branching fraction is reported at \calB(b → s γ) = (3.15 ± 0.35 ± 0.32 ± 0.26)× 10^-4, where the first uncertainty is statistical, the second is systematic, and the third for model dependence. We also describe a new analysis performed to search for CP asymmetry in b → s γ decays. We observe no such asymmetry and set conservative limits at -0.09
