Measurement of $CP$ asymmetries in $B^0\to K_S^0{\pi }^0\gamma$ decays at Belle II

Belle II Collaboration, I. Adachi, L. Aggarwal +436

We report measurements of time-dependent $CP$ asymmetries in $B^0\to K_S^0{\pi }^0\gamma$ decays based on a data sample of $(388\pm 6)\times 10^6$ $B\bar{B}$ events collected at the ${\rm Y}(4S)$…
