Abstract
Exchange of unparticle stuff of dimension dU with FCNC interaction can induce M12,u and Γ12,u causing meson and antimeson mixing with the relation Γ12,u/M12,u=2tan(πdU). We show that this type of unparticle contribution can provide the much needed large Γs12 to explain the recently observed anomalously large dimuon asymmetry in Bs–B¯s system reported by D0 Collaboration. The same interaction can also accommodate large mixing induced CP violation in Bs→J/ψϕ indicated by CDF and D0 data. Experimental data can provide constraints on the unparticle dimension and scale.
