First Observation of the Radiative Decay $D^{0} \to γ ω$

BESIII Collaboration, M. Ablikim, M. N. Achasov +767

We report the first observation of the radiative charm decay $D^{0} \to γ ω$ with a significance of $6.0 σ$ . The analysis uses 20.3\, $fb^{- 1}$ of $e^{+} e^{-}$ collision data collected…
