Large dimuon asymmetry in Bs-B¯s mixing from unparticle induced Γs12
چکیده انگلیسی
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.
