Abstract [en]

Using a 2.93 fb(-1) data sample of electron-positron collisions taken with the BESIII detector at a center-of-mass energy of 3.773 GeV, which corresponds to (8296 +/- 31 +/- 64) x 10(3) D+ D- pairs, we search for the baryon and lepton number violating decays D+ -> (Lambda) over bar((Sigma) over bar (0))e(+) and D+ -> Lambda(Sigma(0))e(+). No obvious signals are found with the current statistics and upper limits on the branching fractions of these four decays are set at the level of 10(-6) at 90% confidence level.
