Abstract

Based on a data sample of (448.1±2.9)×106ψ(3686) decays collected with the BESIII experiment, a search for the flavor changing neutral current transition ψ(3686)→Λc+pe+e-+c.c. is performed for the first time. No signal candidates are observed and the upper limit on the branching fraction of ψ(3686)→Λc+pe+e- is determined to be 1.7×10-6 at the 90% confidence level. The result is consistent with expectations from the standard model, and no evidence for new physics is found.
