Query: D rare/forbidden decays at BESIII   In this document we present the latest result on rare/forbidden decays for D
mesons at the BESIII experiment. Based on 2.92/fb data taken at the
center-of-mass energy 3.773 GeV with the BESIII detector, the flavor-changing
neutral current process of neutral D decays into two gammas is searched using a
double tag technique, while the decays of charged D decays into a charged
kaon/pion plus two electrons/positrons are studied based on a single tag
method. The resulting upper limits are still above the Standard Model
predictions.
