Improved analysis of neutral pion electroproduction off deuterium in chiral perturbation theory
arXiv:nucl-th/0405006 · doi:10.1140/epja/i2004-10052-6
Abstract
Near threshold neutral pion electroproduction on the deuteron is studied in the framework of heavy baryon chiral perturbation theory. We include the next-to-leading order corrections to the three-body contributions. We find an improved description of the total and differential cross section data measured at MAMI. We also obtain more precise values for the threshold S-wave multipoles. We discuss in detail the theoretical uncertainties of the calculation.
