We point out a redundancy in the operator structure of the pionless effective field theory which dramatically simplifies computations. This redundancy is best exploited by using dibaryon fields as fundamental degrees of freedom. In turn, this suggests a new power counting scheme which sums range corrections to all orders. We explore this method with a few simple observables: the deuteron charge form factor, n p -> d gamma, and Compton scattering from the deuteron. Higher dimension operators involving electroweak gauge fields are not renormalized by the s-wave strong interactions, and therefore do not scale with inverse powers of the renormalization scale. Thus, naive dimensional analysis of these operators is sufficient to estimate their contribution to a given process.

  1. Deuterium-Proton Fusion in an Effective Field Theory Constructed from On-Shell Amplitudes

    nucl-th 2026-07 conditional novelty 7.0 of 10

    A nuclear-state on-shell EFT yields S(0)=0.209±0.008 eV b for d(p,γ)3He and traces the ab initio-data offset to a natural t_E1≈−0.15 contact term.

  2. Unnuclear matter at large-charge

    nucl-th 2025-01 conditional novelty 6.0 of 10

    In the large-charge EFT of neutrons, effective-range corrections to the two-point function first appear at second order in the effective range, and the deformed theory has a narrow but usable perturbative window for Q...

  3. Bootstrapping Two-Nucleon Effective Field Theories

    nucl-th 2026-05 unverdicted novelty 5.0 of 10

    Bootstrap consistency checks show that the NLO chiral EFT potential for the 1S0 two-nucleon wave remains valid over a significantly wider energy range than the LO version when compared to Granada phase shifts.
