摘要
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.
