Understand

Unparticles proposed by Georgi carry CP conserving phases in their propagators.

We demonstrate that these peculiar phases have an important impact on CP violation.
Without including the strong QCD phases, we study the unparticle phase effects on the direct CP asymmetries in the exclusive decays of $\bar B_d\to \pi^{+} \pi^{-}$ and $B\to \pi K$, in which the flavor changing neutral currents are forbidden at tree level but induced by one-loop diagrams.
Interesting and consistent results comparing to the data are obtained.
