In this process, both baryon and lepton number conservation is violated. No signal is found and the upper limit on the branching fraction B(J/psi -> Lambda(+)(c)e(-) + c.c.) is set to be 6.9 x 10(-8) at the 90% confidence level.eninfo:eu-repo/semantics/openAccessFINAL-STATESSearch for baryon and lepton number violation in J/psi -> Lambda(+)(c)e(-) + c.c.Article2-s2.0-8506520994810.1103/PhysRevD.99.072006Q1WOS:000464742700003
