Probing the unparticle signal in $b\to d$ penguin processes

Abstract

We investigate the effect of unparticles in the pure $b\to d$ penguin processes $B^0\to K^0{\bar{K}}^0$ and $B^{+,0}\to \varphi {\pi }^{+,0}$. Since these processes receive dominant contributions due to the {\it top} quark in the loop, direct and mixing-induced CP asymmetry parameters in these processes are expected to be vanishingly small in the standard model. We find that due to the unparticle effect sizable nonzero CP violation could be possible in these channels.
