Abstract

We study the characteristics of the low mass p over(p, ̄) enhancements near threshold in the three-body decays B⁺ → p over(p, ̄) K⁺ and B⁺ → p over(p, ̄) π⁺. We observe that the proton polar angle distributions in the p over(p, ̄) helicity frame in the two decays have the opposite polarity, and measure the forward-backward asymmetries as a function of the p over(p, ̄) mass for the p over(p, ̄) K⁺ mode. We also search for the intermediate two-body decays, B⁺ → over(p, ̄) Δ^{+ +} and B⁺ → p over(Δ, ̄)⁰, and set upper limits on their branching fractions. These results are obtained from a 414 fb^-1 data sample that contains 449 × 10⁶ B over(B, ̄) events collected near the Υ{hooked} (4 S) resonance with the Belle detector at the KEKB asymmetric-energy e⁺ e^- collider.
