Title: Search for B 0 p Λ ¯ π γ at Belle

Abstract

We search for the charmless B0 decay with final state particles p¯Λπγ using the full data sample that contains 772 × 106BB¯ pairs collected at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e collider. Here, this decay is predicted to proceed predominantly via the b → sγ radiative penguin process with a high energy photon. No significant signal is found. As a result, we set an upper limit of 6.5 × 10–7 for the branching fraction of B0 → p¯Λπγ at the 90% confidence level.
