Dibaryon signals in the excitation functions of polarized πd scattering

Quantitative estimates of the role of the dibaryon resonances ¹D₂, ³F₃ and ¹G₄ in the πd channel are made. Exc functions for vector and tensor polarisations for πd → π$\text{d}$ are calculated for T^π < 650 MeV by admixing dibaryon resonances of conservative strength to the impulse approximation background. The reliability of the background amplitudes for θ ? 70° is checked by comparing with results from a Faddeev calculation.
