Abstract
Using an electron-positron collision data sample corresponding to an integrated luminosity of 2.93 fb(-1) collected with the BESIII detector at a center-of-mass energy of 3.773 GeV, we search for the baryon-number and lepton-number violating decays D-0 -> (p) over bare(+) and D-0 -> pe(-). No obvious signals are found with the current statistics. The upper limits on the branching fractions for D-0 -> (p) over bare(+) and D-0 -> pe(- )are set to be 1.2 x 10(-6) and 2.2 x 10(-6) at 90% confidence level, respectively.File in questo prodotto:
