Measurement of time-dependent $CP$ violation parameters in $B^0\to K_S^0{\pi }^0\gamma$ decays at Belle and Belle II

Belle, Belle II Collaborations, : +417

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