Abstract: Coherent 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 MAML We also obtain more precise values for the threshold S-wave multipoles. We discuss in detail the theoretical uncertainties of the calculation.
