  • Results are presented from a search for the rare decays B(s) to mu+ mu- and B0 to mu+ mu- in pp collisions at sqrt(s) = 7 and 8 TeV, with data samples corresponding to integrated luminosities of 5 and 20 inverse femtobarns, respectively, collected by the CMS experiment at the LHC. An unbinned maximum-likelihood fit to the dimuon invariant mass distribution gives a branching fraction B(B(s) to mu+ mu-) = (3 +1.0/-0.9)E-9, where the uncertainty includes both statistical and systematic… CONTINUE READING
