Rate and CP-asymmetry sum rules in B→Kπ
Abstract
The observed violation of ACP(B0→K+π-)=ACP(B+→K+π0) has been recently mentioned as a puzzle for the standard model. We point out that while this violation may be accounted for by a large color-suppressed tree amplitude, a sum rule involving three or four B→Kπ CP asymmetries should hold. The current experimental status of these sum rules and of a sum rule for B→Kπ decay rates is presented.
