Study of ${\bar{K}}^{\ast }(892{)}^0\hat{I}\cdot$ and $K_S^0{a}_0(980{)}^0$ in the $D^0\to K_S^0\ddot{I}{€}^0\hat{I}\cdot$ decay

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