Measurement of time-dependent $CP$ asymmetries in $B^0\to K_{\mathrm{S}}^0\ddot{I}{€}^{+}\ddot{I}{€}^{-}{\hat{I}}^3$ decays at Belle and Belle II

Belle, Belle II Collaborations, : +350

We present a measurement of the time-dependent $CP$ asymmetry in $B^0\to K_{\mathrm{S}}^0\ddot{I}{€}^{+}\ddot{I}{€}^{-}{\hat{I}}^3$ decays using a data set of 365 fb${}^{-1}$ recorded by the Belle II experim…
