摘要
The angular distributions of the baryon-antibaryon low-mass enhancements seen in the charmless three-body baryonic B decays B +→pp̄ K +, B 0→pp̄K S 0 and B 0→pΛ̄π - are reported. A quark fragmentation interpretation is supported, while the gluonic resonance picture is disfavored. Searches for the Θ + and Θ ++ pentaquarks in the relevant decay modes and possible glueball states G with 2.2 GeV/c 2<M pp̄<2.4 GeV/c 2 in the pp̄ systems give null results. We set upper limits on the products of branching fractions, Β(B 0→Θ +p̄) Β(Θ +→pK S 0)<2.3×10 -7, Β(B +→Θ ++p̄) Β(Θ ++→pK +)<9.1×10 -8, and Β(B +→GK +)B(G→pp̄)<4. 1×10 -7 at the 90% confidence level. The analysis is based on a 140 fb -1 data sample recorded on the Υ(4S) resonance with the Belle detector at the KEKB asymmetric energy e +e - collider.

N2 - The angular distributions of the baryon-antibaryon low-mass enhancements seen in the charmless three-body baryonic B decays B +→pp̄ K +, B 0→pp̄K S 0 and B 0→pΛ̄π - are reported. A quark fragmentation interpretation is supported, while the gluonic resonance picture is disfavored. Searches for the Θ + and Θ ++ pentaquarks in the relevant decay modes and possible glueball states G with 2.2 GeV/c 2<M pp̄<2.4 GeV/c 2 in the pp̄ systems give null results. We set upper limits on the products of branching fractions, Β(B 0→Θ +p̄) Β(Θ +→pK S 0)<2.3×10 -7, Β(B +→Θ ++p̄) Β(Θ ++→pK +)<9.1×10 -8, and Β(B +→GK +)B(G→pp̄)<4. 1×10 -7 at the 90% confidence level. The analysis is based on a 140 fb -1 data sample recorded on the Υ(4S) resonance with the Belle detector at the KEKB asymmetric energy e +e - collider.
