No significant signal is observed, and an upper limit of B(Ds+?ppe+?e)<2.0×10-4 is set at the 90% confidence level. This measurement is useful input in understanding the baryonic transition of Ds+ mesons.eninfo:eu-repo/semantics/openAccessSearch for the decay Ds+ ?p p e+?e SEARCH for the DECAY Ds+ ?p p e+?eArticle2-s2.0-8507739669110.1103/PhysRevD.100.112008N/AWOS:000504637500002
