Large Dimuon Asymmetry In Bs-bar B_s Mixing From Unparticle Indced Gamma^{12}_s

Abstract

Exchange of unparticle stuff of dimension $d_\U$ with FCNC interaction can induce $M^{12,u}$ and ${\Gamma }^{12,u}$ causing meson and anti-meson mixing with the relation $Γ^{12,u}/M^{12,u} = 2 \tan(πd_\U)$. We show that this type of unparticle contribution can provide the much needed large ${\Gamma }_s^{12}$ to explain the recently observed anomalously large dimuon asymmetry in $B_s-{\bar{B}}_s$ system reported by D0 collaboration. The same interaction can also accommodate large mixing induced CP violation in $B_s\to J/\psi \varphi$ indicated by CDF and D0 data. Experimental data can provide constraints on the unparticle dimension and scale.
