Search for the rare decay $J / ψ \to γ D^{0} + c . c .$ at BESIII

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

Using $(10087 \pm 44) \times 1 0^{6} J / ψ$ events collected with the BESIII detector, we search for the rare decay $J / ψ \to γ D^{0} + c . c .$ for the first time. No obvious signal is observed and t…

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

By analyzing 7.33\,fb $^{- 1}$ of $e^{+} e^{-}$ collision data collected at center-of-mass energies between 4.128 and 4.226 GeV with the BESIII detector, we search for the semileptonic de…
