Search for $J/\psi$ weak decays containing $D$ meson

BESIII Collaboration, M. Ablikim, M. N. Achasov +611

Using a sample of about 10 billion $J/\psi$ events with the BESIII detector, we search for the weak decays of $J/\psi \to {\bar{D}}^0{\pi }^0+c.c.$, $J/\psi \to {\bar{D}}^0\eta +c.c.$, $J/ψ\to \bar{D}^…
