Determination of U-spin breaking parameters with an amplitude analysis of the decay $D^{0} \to K_{L}^{0} π^{+} π^{-}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +605

We present a study of the resonant structure of the decay $D^{0} \to K_{L}^{0} π^{+} π^{-}$ , using quantum-correlated $D^{0} D ˉ^{0}$ data produced at $s = 3.773$ GeV. The data sampl…

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}(…
