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