pp scattering in lD2 state

Abstract
Pp scattering in the 1D2 state is investigated in a multichannel N/D formalism with pp → pp, pp → NΔ, and NΔ → NΔ as the coupled channels. The driving force is calculated in the OPE and OBE approximations. The resulting 1D2 amplitude has the standard resonance-like features but has no complex pole corresponding to a diproton resonance.
