Abstract
Recent measurements of the time-dependent CP asymmetry of the B → φKS decay give results whose central values differ from standard model expectations. It is shown how such data can be used to identify new physics contributions in a model-independent manner. In general, a sizable new amplitude with nontrivial weak and strong phases would be required to explain current data. An improvement in the quality of data will allow one to form a more definite conclusion. © 2003 The American Physical Society.
