Measurement of the B+-> p(p)over-barK(+) branching fraction and study of the decay dynamics
With a sample of 232×106 Υ(4S)→BB̄ events collected with the BABAR detector, we study the decay B+→pp̄K+ excluding charmonium decays to pp̄. We measure a branching fraction B(B+→pp̄K+)=(6.7±0.5±0.4)×10-6. An enhancement at low pp̄ mass is observed and the Dalitz plot asymmetry suggests dominance of...
