本文研究了非粒子作为衰变B → K（K*）+丢失能量的可能来源的影响。我们发现，在矢量非粒子算符存在下，微分分支比对K（K*）介子能量的依赖性与SM有很大区别。此外，在利用已有的B → K（K*）+丢失能量衰变的上界时，我们已经能够对非粒子填充的参数提出更严格的约束。
In the present work we study the effects of an unparticle 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.
