Measurement of time-dependent $CP$ violation parameters in $B^0\to K_S^0\ddot{I}{€}^0{\hat{I}}^3$ decays at Belle and Belle II

Belle, Belle II Collaborations, : +416

We perform a measurement of time-dependent $CP$ violation parameters in $B^0\to K_S^0\ddot{I}{€}^0{\hat{I}}^3$ decays using a dataset of approximately $772\times 10^6$ and $521 \times 10…
