The observed number of candidates is consistent with the background-only hypothesis, yielding an upper limit of B(K0S→μ+μ−) < 11(9) × 10−9 at 95 (90)% confidence level. This limit is a factor of thirty below the previous measurement.18 p.application/pdfengcc-by (c) LHCb Collaboration, 2013http://creativecommons.org/licenses/by/3.0/es/Teoria quàntica de campsGravitacióRelativitat (Física)Teoria quànticaQuantum field theoryGravitationRelativity (Physics)Quantum theoryinfo:eu-repo/semantics/article6196332014-09-23info:eu-repo/semantics/openAccess
