Observation of an Altered $a_{0} (980)$ Line-shape in $D^{+} \to π^{+} η η$ due to the Triangle Loop Rescattering Effect

BESIII Collaboration, M. Ablikim, M. N. Achasov +697

Using 20.3~ $fb^{- 1}$ of $e^{+} e^{-}$ collision data taken with the BESIII detector at the center-of-mass energy 3.773~GeV, we report the first amplitude analysis of the hadro…
