摘要：

We calculate the effect of new CP violating interactions parameterized by an anomalous tbW coupling on CP-odd observables in B decays. We find that couplings consistent with current bounds induce observable effects in some CP asymmetries that will be measured in B-factories. The new effects are sufficiently large that they can actually test specific models that give rise to these tbW interactions. (C) 1997 Published by Elsevier Science B.V.
