Abstract

We prove an approximate relation, to leading order in dominant terms, between CP-violating rate differences in B0/Bˉ0K±πB^0/\bar{B}^0 \to K^{\pm}\pi^{\mp} and B±K±π0B^{\pm} \to K^{\pm}\pi^0. We show how data from these two processes may be combined in order to enhance the significance of a nonzero result.
