Three-body calculation ofπdelastic scattering observables at energies up to the (3,3) resonance

Abstract

The $\pi d$ elastic scattering observables are calculated in the energy range 25 to 180 MeV on the basis of the Faddeev-Lovelace equations where relativistic kinematics are used only for the pion. In the (3,3) resonance region, the importance of all $S$, $P$ $\pi N$ channels (included in an exact way) and the sensitivity to the description of the deuteron wave function are demonstrated. The vector and tensor polarizations are predicted at 142 and 180 MeV.
