Search for the ${\mathbf{B}}^0\to {\mathbf{K}}_{\mathrm{S}}^0{\mathbf{\tau }}^{+}{\mathbf{\tau }}^{-}$ decay

Belle, Belle II Collaborations, : +432

We present the first search for $B^0\to K_{\mathrm{S}}^0{\tau }^{+}{\tau }^{-}$ decays. We look for signal decays in $B^0{\bar{B}}^0$ events produced in asymmetric-energy electron-positron collisions. T…
