What can we learn from an explicit treatment of the π in the three-nucleon system? Original Research Article

An explicit treatment of the pion dynamics in the three-nucleon system leads quite naturally to the hypotesis of a residual, effective interaction mechanism between a correlated pair and a spectator nucleon. We discuss the diagrams that generate this effect and review some of the results that have been obtained in neutron-deuteron scattering at moderate energies following this approach.
