First Observation of the Direct Production of the $χ_{c 1}$ in $e^{+} e^{-}$ Annihilation

BESIII Collaboration

We study the direct production of the $J^{P C} = 1^{++}$ charmonium state $χ_{c 1} (1 P)$ in electron-positron annihilation by carrying out an energy scan around the mass of the $χ_{c1}(…
