B -> K(K^*)X: Decay Distributions, Branching Ratios and CP Asymmetries

Abstract

We discuss an improved theoretical description of the semi-inclusive B meson decays $B\to K(K^*)X$. The decay distributions are calculated. Their branching ratios are found to be appreciable. The CP asymmetries in the neutral B modes $\bar{B^0}\to K^-(K^{*-})X$ are sizable. An observation of direct CP violation and a measurement of $\gamma$ may come from these neutral B modes.
