Abstract
Exchange of unparticle stuff of dimension dU with FCNC interaction can induce M12,u and Î12,u causing meson and antimeson mixing with the relation Î12,u/M12,u=2tan(ÏdU). We show that this type of unparticle contribution can provide the much needed large Îs12 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 BsâJ/ÏÏ indicated by CDF and D0 data. Experimental data can provide constraints on the unparticle dimension and scale.
