Unparticle effect on B_s - \bar B_s mixing and its implications for B_s \to J/\psi \phi, \phi \phi decays

Abstract

We study the effect of unparticle stuff on $B_s-{\bar{B}}_s$ mixing and consider possible implications of it for the decaymodes $B_s\to J/\psi \varphi$ and $\varphi \varphi$. We find that due to the new contributions from the unparticles the $B_s-{\bar{B}}_s$ mixing phase could be observable at the LHC along with the possible sizable CP asymmetry parameters $S_{\psi \varphi (\varphi \varphi )}$ in $B_s\to J/\psi \varphi (\varphi \varphi )$ decay modes.
