Pion--deuteron scattering length in Chiral Perturbation Theory up to order Ï^{3/2}
arXiv:0711.2743
Abstract
A complete calculation of the corrections to pion-deuteron scattering length up to order $Ï^{3/2}$ with $Ï=m_Ï/M_{N}$ is performed. The calculation includes the dispersive contributions and corrections due to the explicit treatment of the $Î$ resonance. s-wave pion-nucleon scattering parameters are extracted from a combined analysis of modern experimental data.
