No significant signal is observed, and an upper limit is set on the branching fraction B(J/psi -> e(+/-)tau(-/+)() <) 7.5 x 10(-8) at the 90% confidence level. This improves the previously published limit by two orders of magnitude.eninfo:eu-repo/semantics/openAccessMuonNumberHiggsTofArticle2-s2.0-8510891774810.1103/PhysRevD.103.11200711Q1103Q1WOS:000665619100001
