We do not observe any signal and set an upper limit on the branching fraction of 14.3×10-5 at 90% confidence level. This result represents a significant improvement over the previous most stringent limit.7 page(s)application/pdfenIn CopyrightPhysicsArticle - Refereedhttps://doi.org/10.1103/PhysRevD.105.0120071051Piilonen, Leo [0000-0001-6836-0748]2470-0029
