In all six decay modes considered, the numbers of events found in data are compatible with the background expectations. Upper limits on the branching fractions are set in the range ( 1.8 - 3.3 ) × 10 − 8 at 90% confidence level.8 p.application/pdfeng(c) American Physical Society, 2010Física de partículesExperimentsParticle physicsExperimentsinfo:eu-repo/semantics/article6019402019-04-08info:eu-repo/semantics/openAccess
