We measure for the first time the B0→pς¯0π- branching fraction to be B(B0→pς¯0π-)=(1.17-0.40+0.43(stat)±0.07(syst))×10-6 with a significance of 3.0σ. We simultaneously measure the branching fraction for the related channel B0→pΛ¯π- with much improved precision.Pages 052011In Copyright5106 Nuclear and Plasma Physics5107 Particle and High Energy Physics4902 Mathematical Physics49 Mathematical Sciences51 Physical SciencesArticle - Refereedhttps://doi.org/10.1103/PhysRevD.108.0520111085Piilonen, Leo [0000-0001-6836-0748]2470-0029
