I summarize two recent applications of chiral perturbation theory (χPT) to electromagnetic reactions on deuterium: elastic electron–deuteron scattering and Compton scattering on deuterium. Both calculations have now been carried out to three orders in the chiral expansion. The expansion shows good convergence and is able to reproduce data for | q | ≲ 600 MeV in ed and for ω = 55–95 MeV in γ d . These results demonstrate that χPT can be used to reliably compute operators and wavefunctions for low-momentum-transfer reactions in light nuclear systems.
