Differential cross sections for neutron-proton scattering in the region of the d*(2380) dibaryon resonance
Differential cross sections have been extracted from exclusive and kinematically complete high-statistics measurements of quasifree polarized np scattering performed in the energy region of the d∗(2380) dibaryon resonance covering the range of beam energies Tn = 0.98−1.29 GeV (√s = 2.32−2.44 GeV).

| Summary: | Differential cross sections have been extracted from exclusive and kinematically complete high-statistics measurements of quasifree polarized np scattering performed in the energy region of the d∗(2380) dibaryon resonance covering the range of beam energies Tn = 0.98−1.29 GeV (√s = 2.32−2.44 GeV). The experiment was carried out with the WASA-at-COSY setup having a polarized deuteron beam impinged on the hydrogen pellet target and utilizing the quasifree process dp→ np + pspectator . In this way the np differential cross section σ () was measured over a large angular range. The obtained angular distributions complement the corresponding analyzing power Ay() measurements published previously. A SAID partial-wave analysis incorporating the new data strengthens the finding of a resonance pole in the coupled 3D3 - 3G3 waves. |
