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 × 10 6 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.
