The observation of the decay mode B∓ → pp̄K∓ based on an analysis of 29.4 fb-1 of data collected by the Belle at KEKB was reported. A 29.4 fb-1 data sample, containing 31.9 × 106 produced BB̄ pairs, collected with the Belle detector at the KEKB asymmetric-energy e+e- was used. The results showed that the pp̄ mass spectrum in this decay was inconsistent with phase space and was peaked at low mass.
