Abstract

The difference in the time dependent CP asymmetries between the modes B→ψK_s and B→φK_s is a clean signal for physics beyond the standard model. This interpretation could fail if there is a large enhancement of the matrix element of the b→uūs operator between the B_d initial state and the φK_s final state. We argue against this possibility and propose some experimental tests that could shed light on the situation.
