Nucleon Nucleon Interaction

We consider the counter-term describing isoscalar axial two-body currents in the nucleon–nucleon interaction, L1A, in the effective field theory approach. We determine this quantity using solar neutrino data. We investigate the variation of L1A when different sets of data are used.

Interaction Problem

It is argued that Weinberg's approach to the nucleon–nucleon (NN) interaction problem within effective field theory provides a consistent power counting for renormalized diagrams. Within this scheme the NN potential is organized as an expansion in terms of small quantities like small external momenta and the pion mass (divided by the characteristic large scale of the effective theory). Physical observables to any given order in these small quantities are calculated from the solutions of the Lippmann–Schwinger (or Schrödinger) equation.
