Study of $K ˉ^{*} (892)^{0} I^\cdot$ and $K_{S}^{0} a_{0} (980)^{0}$ in the $D^{0} \to K_{S}^{0} I ¨ ^{0} I^\cdot$ decay

BESIII Collaboration, M. Ablikim, M. N. Achasov +666

We perform an amplitude analysis of the decay $D^{0} \to K_{S}^{0} I ¨ ^{0} I^\cdot$ and measure its absolute branching fraction to be $(1.016 \pm 0.013_{\text {stat.}} \pm 0.014_{\text {syst.}})…
