On the rare B_s to two muons decay and noncontractibility of the   physical space
  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.
