关于B_s到两μ子的稀有衰变和物理空间的不可收缩性
On the rare B_s to two muons decay and noncontractibility of the physical space
摘要：
众所周知，罕见的电弱过程对标准模型之外的物理非常敏感。这些过程用包含重粒子的量子回路图来描述。我们证明了在不考虑Higgs标量的情况下，作为一种破缺机制的不可收缩空间的电弱理论，从本质上改变了标准模型对B_s介子衰变为两个μ子的分支比的预言.与标准模型结果相比，分支比降低了30%以上。虽然测量是非常具有挑战性的，选择的破胶机制可能是决定性的。
英文摘要：
It is very well known that the rare electroweak processes could be very sensitive to the physics beyond the Standard Model. These processes are described with quantum loop diagrams containing also heavy particles. We show that the electroweak theory with the noncontractible space, as a symmetry-breaking mechanism without the Higgs scalar, essentially changes the Standard Model prediction of the branching ratio of the B_s meson decaying to two muons. The branching ratio is lower by more than 30% compared with the Standard Model result. Although the measurements are very challenging, the implications on the selection of the symmetry-breaking mechanism could be decisive.
