The observation of B+ → pp̄π+, which is dominated by the b→u tree diagram was studied. The observation of B 0 → pp̄K0 and B+→pp̄K *+ was also presented and the mesurement of B +→pp̄K+ was improved. It was found that a search for the B0→pp̄K*0 mode yielded only an upper limit. The pp̄ mass spectra was also studied to see if the threshold peaking confirmed with the newly observed modes.
