dc.descriptionWe present a parameter--free calculation of the dispersive and absorptive contributions to the pion--deuteron scattering length based on chiral perturbation theory. We show that once all diagrams contributing to leading order to this process are included, their net effect provides a small correction to the real part of the pion--deuteron scattering length. At the same time the sizable imaginary part of the pion--deuteron scattering length is reproduced accurately.
dc.descriptionNumerical error corrected. Results for dispersive corrections changed - conclusions unchanged. Version as accepted by Phys. Lett. B
