$b\to s{\hat{I}}^3$ Branching Fraction and CP Asymmetry

Abstract

We present preliminary results on $b\to s{\hat{I}}^3$ from the CLEO experiment. An updated result on the branching fraction is reported at $\mathcal{B}$$(b\to s{\hat{I}}^3)=(3.15\pm 0.35\pm 0.32\pm 0.26)\times 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 $b\to s{\hat{I}}^3$ decays. We observe no such asymmetry and set conservative limits at $-0.09<$ $\mathcal{A}$ $<0.42$.
