N2 - We apply Wick's three-body helicity formalism, to covariantly reduce the relativistic Faddeev equations that describe pion-deuteron elastic scattering, obtaining a set of equations that satisfy two- and three-body unitarity and are Lorentz invariant with regard to both the space and the spin variables. We use all the pion-nucleon S and P-wave channels and the two nucleon-nucleon S-wave channels as input, to give a good description of the data for pion kinetic energies in the region from 142 MeV up to 512 MeV.
