  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.
