Abstract
Within the standard model, CP rate asymmetries for B → K- π+,0 could reach 10%. With strong final state phases, they could go up to 20% – 30%, even for the K¯0π- mode which would have the opposite sign. We can account for K-π+, K¯0π-, and φK rate data with new physics enhanced color dipole coupling and destructive interference. Asymmetries could reach 40%–60% for Kπ and φK modes and are all of the same sign. We are unable to account for the K-π0 rate. Our inclusive study supports our exclusive results. © 1998 The American Physical Society.
