Abstract

The result of a search for the flavor changing neutral current (FCNC) process of D0 → γγ was reported. As such, no significant signal for this decay mode was observed and the first 90% C.L. upper limits on the given branching fractions was determined. This result was an order of magnitude above a theoretical prediction.
