Possible signatures of unparticles in rare annihilation type B decays

Abstract

We investigate the effect of unparticles in the pure annihilation type decays $B^{-}\to D_s^{-}\varphi$ and $D_s^{-}{K}^{\ast 0}$. Since these decays have only annihilation contributions their branching ratios are expected to be very small in the standard model and the direct CP asymmetry parameters to be zero. We find that due to the unparticle effect these branching ratios can be significantly enhanced from their standard model values. Furthermore, sizable nonzero direct CP violation could also be possible in these channels due to the presence of intrinsic CP conserving phase in the unparticle propagator.
