Scientific paper

We make a systematic analysis of the effects of new physics in the B decay amplitudes on the CP asymmetries in neutral B decays. Although these are expected to be smaller than new physics effects on the mixing amplitude, they are easier to probe in some cases. The effects of new contributions to the mixing amplitude are felt universally across all decay modes, whereas the effects of new decay amplitudes could vary from mode to mode. In particular the prediction that the CP asymmetries in the B decay modes with $b\to c\bar c s$, $b \to c\bar c d$, $ b\to c \bar u d$ and $ b\to s \bar s s$ should all measure the same quantity (sin(2\beta) in the Standard Model) could be violated.
