In the limit of flavor SU(3) symmetry, the amplitudes for [Formula Presented] and [Formula Presented] are related to one another. Taking the values of the weak phases [Formula Presented] and [Formula Presented] from independent measurements, the ratio [Formula Presented] and the two [Formula Presented] CP asymmetries [Formula Presented] and [Formula Presented] depend on only two quantities. By measuring these three observables, one can test for the presence of physics beyond the standard model. In this paper, using present data, and including theoretical uncertainties due to SU(3) breaking, we perform such an analysis. The experimental errors are still very large, but with improved measurements from Babar, Belle and CDF this will be a useful method to search for new physics. © 2004 The American Physical Society.
