Abstract:	摘要： A search for the rare decays B_s to mu+ mu- and B^0 to mu^+ mu^- is performed in pp collisions at sqrt(s) = 7 TeV, with a data sample corresponding to an integrated luminosity of 5 inverse femtobarns collected by the CMS experiment at the LHC. In both decays, the number of events observed after all selection requirements is consistent with the expectation from background plus standard model signal predictions. The resulting upper limits on the branching fractions are Br(B_s to mu^+ mu^-) < 7.7E-9 and Br(B^0 to mu^+ mu^-) < 1.8E-9 at 95% confidence level. 出版者： Springer 出版日期： 2012 出處： The journal of high energy physics, 2012, Vol.4 資源來源： ProQuest Publicly Available Content Database 版權： CC0 1.0 - Universal 識別號： ISSN: 1126-6708 識別號： EISSN: 1029-8479 識別號： DOI: 10.1007/JHEP04(2012)033
