Abstract

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.
