  • Evidence for ▫$B^0 \to p\bar{\Sigma}^0 \pi^−$▫ at Belle
    Chang, C.-Y. ...
    We search for the B0 → pΣ¯ 0π− decay with Σ¯ 0 → Λ¯ γ, where the γ is not measured, using a data sample corresponding to an integrated luminosity of 711 fb−1 which contains 772 × 106 BB¯ pairs, ... collected around the ϒð4SÞ resonance with the Belle detector at the KEKB asymmetric-energy eþe− collider. We measure for the first time the B0 → pΣ¯ 0π− branching fraction to be BðB0 → pΣ¯ 0π−Þ¼ð1.17þ0.43 −0.40 ðstatÞ 0.07ðsystÞÞ × 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.
