Abstract

The angular distributions of the baryon-antibaryon low-mass enhancements seen in the charmless three-body baryonic B decays B⁺ → p pbar K⁺, B⁰ → p pbar K_S⁰, and B⁰ → p Lambdabar pi^- are reported. Searches for the pentaquarks Theta⁺ and Theta⁺⁺ in the relevant decay modes and possible glueball states in the p pbar systems are presented. The analysis is based on a 140 fb^-1 data sample recorded on the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e⁺e^- collider.
