We present a power counting to include Coulomb effects in the three-nucleon system in a low-energy pionless effective field theory (EFT). With this power counting, the quartet S-wave proton-deuteron elastic scattering amplitude is calculated. The calculation includes next-to-leading order (NLO) Coulomb effects and next-to-next-to-leading order (NNLO) strong interaction effects, with an estimated theoretical error of about 7 %. The EFT results agree with potential model calculations and phase shift analysis of experimental data within the estimated errors.

Discussion (0). Continue with ORCID to comment.

  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. Coulomb Corrections to Three-Nucleon Moments

    nucl-th 2026-05 unverdicted novelty 4.0 of 10

    Pionless EFT calculations find unexpectedly small O(alpha) Coulomb corrections to three-nucleon magnetic moments and GT matrix elements, yielding a fitted prediction for the proton-proton fusion reduced matrix element...
