Search for the rare decay $J/\psi \to \gamma D^0+c.c.$ at BESIII

BESIII Collaboration, M. Ablikim, M. N. Achasov +650

Using $(10087\pm 44)\times 10^{6}J/\psi$ events collected with the BESIII detector, we search for the rare decay $J/\psi \to \gamma D^0+c.c.$ for the first time. No obvious signal is observed and t…
