Measurement of $CP$ violation in $B^0\to K_S^0\ddot{I}{€}^0$ decays at Belle II

Belle II Collaboration, I. Adachi, K. Adamczyk +399

We report a measurement of the $CP$-violating parameters $A$ and $S$ in $B^0\to K_S^0\ddot{I}{€}^0$ decays at Belle II using a sample of $387\times 10^6$ $B\bar{B}$ events reco…
