sentences:  The branching fraction of the strange b-meson to a pair of muons is very precisely predicted with a value of Br(Bs→ µ+µ−)SM = (3.66 ± 0.23) × 10−9.Any variation from this rate would indicate possible physics beyond the standard model, such as supersymmetry.The first definitive measurement was made from a combination of LHCb and CMS experiment data
