摘要
In the present work we study the effects of an unparticle U as the possible source of missing energy in the decay B -> K(K*) + missing energy. We find that the dependence of the differential branching ratio on the K(K*)-meson's energy in the presence of the vector unparticle operators is very distinctive from that of the SM. Moreover, in using the existing upper bound on B -> K(K*) + missing energy decays, we have been able to put more stringent constraints on the parameters of unparticle stuff.
