P-matrix analysis of the 1D2 resonance

The relation between the six-quark states of the bag model and the nucleon-nucleon scattering in the dibaryon-resonance is discussed. The data on existing phase-shift analysis are employed to calculate the P matrix for the coupled pp (1D2) and NΔ(5S2) channels in the energy range above the Δ-isobar production threshold. The P matrix calculated for the equivalent hadronic gab radii b=1.3-1.5 Fm is shown to have a pole in the mass range 2.33-2.36 GeV is in agreement with the MIT bag model prediction of the I=1, Jsup(P)=2sup(+) six-quark state with the mass 2.34 GeV. The hadronic shift of this state is shown to be approximately 200 MeV; the dibaryon pole of the S matrix corresponds to the mass 2.15-2.17 GeV with the width approximately 100-200 MeV
