Abstract
B → K*π and B → ρK decays involve the same quark-level processes as B → πK. Analyzing the measurements of the former decays might be able to shed additional light on the new-physics hints in the current B → πK data. We perform fits to B → K*π and B → ρK decays, and find that the data can be accommodated within the standard model. However, this agreement is due principally to the large errors in the data, particularly the CP-violating asymmetries. If the errors on the B → K*π and B → ρK observables can be reduced, one will have a clearer sense of whether new physics is present in these decays. © 2009 World Scientific Publishing Company.
