We report a search for the charmless hadronic decay ${B}^{0}\ensuremath{\rightarrow}\ensuremath{\eta}{\ensuremath{\pi}}^{0}$ with a data sample corresponding to an integrated luminosity of $694\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ containing $753\ifmmode\times\else\texttimes\fi{}1{0}^{6}$ $B\overline{B}$ pairs. The data were collected by the Belle experiment running on the $\mathrm{\ensuremath{\Upsilon}}(4S)$ resonance at the KEKB ${e}^{+}{e}^{\ensuremath{-}}$ collider. We measure a branching fraction …
