We report on a search for heavy neutrinos in $B$-meson decays. The results are obtained using a data sample that contains $772\ifmmode\times\else\texttimes\fi{}{10}^{6}B\overline{B}$ pairs collected at the $\ensuremath{\Upsilon}(4S)$ resonance with the Belle detector at the KEKB asymmetric-energy ${e}^{+}{e}^{\ensuremath{-}}$ collider. No signal is observed and upper limits are set on mixing of heavy neutrinos with left-handed neutrinos of the Standard Model in the mass range $0.5--5.0\text{ }\text{ }\mathrm{GeV}/{c}^{2}$.

• Neutrinoless double beta decay versus other probes of heavy sterile neutrinos (2019, methodology): “• The Belle experiment [91] was a B factory that extended the peak search method to higher energies — using BB pairs collected at the Υ(4S) resonance, the decay mode B → (X)`N , with X a charmed meson D(∗) or light meson, could be followed by N → `π (` = e, µ).”
• Physics beyond colliders at CERN: beyond the Standard Model working group report (2019, methodology): “Existing bounds, shown as filled coloured areas, for masses below the charm mass arise mostly from beam dump experiments (PS191 [267] and CHARM [268]) while those above the charm mass from LEP data, dominated by the DELPHI result [266], from Belle [283] and more recently from CMS [284].”
