B \to K(K^*)在非粒子物理学中的能量缺失

B \to K(K^*) missing energy in Unparticle physics

T. M. Aliev, A. S. Cornell, Naveen Gaur

摘要:

在目前的工作中,我们研究的影响,一个非粒子$\unpart$作为可能的来源,在衰变$B \to K (K^*) + {\rm missing energy}$丢失的能量。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的差别很大.此外,在使用现有的上界$B \to K (K^*) + {\rm missing energy}$衰变,我们已经能够把更严格的非粒子材料的参数的限制。

英文摘要:

In the present work we study the effects of an unparticle $\unpart$ as the possible source of missing energy in the decay $B \to K (K^*) + {\rm missing energy}$. 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 $B \to K (K^*) + {\rm missing energy}$ decays, we have been able to put more stringent constraints on the parameters of unparticle stuff.
