Nucleon-Nucleon Scattering and Effective Field Theory: Including Pions Non-perturbatively

Nuclear Theory 2009-10-31 v2 High Energy Physics - Phenomenology

Abstract

Next to leading order effective field theory calculations are performed for 1S0 {}^1S_0 NN scattering using subtractive renormalization procedure. One pion exchange and contact interaction potentials are iterated using Lippman-Schwinger equation. Satisfactory fit to the Nijmegen data is obtained for the momenta up to 300 MeV in the centre of mass frame. Phase shifts are also compared with the results of KSW approach where pions are included perturbatively.
