Pion--deuteron scattering length in Chiral Perturbation Theory up to order 3/2
Abstract
A complete calculation of the corrections to pion-deuteron scattering length up to order 3/2 with =mπ/MN is performed. The calculation includes the dispersive contributions and corrections due to the explicit treatment of the resonance. s-wave pion-nucleon scattering parameters are extracted from a combined analysis of modern experimental data.
