11:00 → 12:00 The 1S0 channel of proton-proton scattering in new chiral effective field theory power counting

In this colloquium, I'll talk about the chiral effective field theory is used to investigate the spin singlet channel 1S0 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.
