Search for D0 → γγ and improved measurement of the branching fraction for D0 → π0π0
Using 2.92 fb−1 of electron-positron annihilation data collected at s√=3.773 GeV with the BESIII detector, we report the results of a search for the flavor-changing neutral current process D0→γγ using a double-tag technique. We find no signal and set an upper limit at 90% confidence level for the...
