This is the first search with the Belle detector for a decay mode including an antineutron. No significant signal is observed and a 90% credible upper limit on the branching fraction is set at 6.3×10−6.application/pdfenIn Copyright5106 Nuclear and Plasma Physics5107 Particle and High Energy Physics51 Physical SciencesArticle - Refereedhttps://doi.org/10.1103/physrevd.108.11200710811Piilonen, Leo [0000-0001-6836-0748]2470-0029
