Abstract:

A unitary analysis for the 1D2-wave pp, 5S2-wave NΔ and 3P2-wave \pid scattering is applied to the NΔ scattering. The experimental phase parameters for the S-wave NΔ scattering are explained on the basis of the S-matrix pole of unstable bound-state type or broad dibaryon, M = 2144 MeV, I = 1, Jp = 2+.

  17. The one-pion-exchange phase shift for pp(1 D2) → NΔ(5 S2) by Kloet and Silbar is consistent with the present δ1∞ + δ2∞ below 500 MeV. Its δ2∞ part is larger by 16° - 17° at 800 MeV. (D. V. Bugg, private communication.) It becomes consistent with the present δ2∞ if the NΔ S-wave short-range repulsion of δ(repul)2∞ ∼ - \tildekRΔ with RΔ ∼ 0.15 fm is introduced.
