Abstract

The effects of the peculiar CP conserving phases in unparticle propagators are explored. We find that the phases have a great impact on CP violation. We adopt the decays Bd→π+π- and Bd→-+ as the illustrators to demonstrate the influences of these phases on the direct CP asymmetries. In particular, we emphasize that unparticle physics is the only model suggested to date that could give the direct CP asymmetries in Bd→-+ as large as 15%. We also point out that the unparticle phases could be probed in B→K*+- decays by using T-odd correlations.
