Interference of dibaryon resonances with Faddeev amplitudes for elastic πd scattering

Abstract

Angular distributions of cross sections and vector and tensor polarisations for pi d to pi d are calculated at Tlabpi =142, 180 and 256 MeV. The isospin-one dibaryon resonances 1D2, 3F3 and 1G4 are mixed into Faddeev partial waves. Using experimental differential cross sections as constraints, dibaryon signals in the polarisation observables are calculated for a range of possible resonance parameters.
