Search for D0→p̄e+ and D0→pe-

Abstract:
We search for simultaneous baryon and lepton number violating decays of the D0 meson. Specifically, we use 281pb-1 of data taken on the ψ(3770) resonance with the CLEO-c detector at the CESR collider to look for decays D0→p̄e+, D̄0→p̄e+, D0→pe-, and D̄0→pe-. We find no significant signals and set the following branching fraction upper limits: D0→p̄e+(D̄0→p̄e+)<1.1×10-5 and D0→pe-(D̄0→pe-)<1.0×10-5, both at the 90% confidence level. © 2009 The American Physical Society.
