Looking for New Physics in B --> K^* π and B --> rho K Decays

B --> K^* \pi and B --> \rho K decays involve the same quark-level processes as B --> \pi K. Analyzing the measurements of the former decays might be able to shed additional light on the new-physics hints in the current B --> \pi K data. We perform fits to B --> K^* \pi and B --> \rho K 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^* \pi and B --> \rho K observables can be reduced, one will have a clearer sense of whether new physics is present in these decays.
