The $$^{1}\!S_{0}$$ 1 S 0 channel of proton–proton scattering in new chiral effective field theory power counting
Abstract In this paper, the chiral effective field theory is used to investigate the spin singlet channel $$^{1\!}S_{0}$$ 1 S 0 , of proton-proton (pp) scattering according to the new suggested power counting. For this purpose, the pp zero scattering amplitude is reproduced by inserting one pion exc...

| description | Abstract In this paper, the chiral effective field theory is used to investigate the spin singlet channel $$^{1\!}S_{0}$$ 1 S 0 , of proton-proton (pp) scattering according to the new suggested power counting. For this purpose, the pp zero scattering amplitude is reproduced by inserting one pion exchange at leading order (LO) and the Coulomb interaction between protons at next-to-leading order (NLO). This leads to a systematic improvement up to NLO compared to the result obtained from Nijm93 potential model. |
