CP Violation in B Decays from Anomalous tbW Interactions

Abstract

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.

We have added a new section showing that the new effects are sufficiently large that they can be measured at a B-factory
