While attempts to solve the equations of Quantum Chromodynamics (QCD) numerically in the low energy limit are increasingly successful ("lattice QCD"), Chiral Ef

This book provides a comprehensive overview of some key developments in the understanding of the nucleon-nucleon interaction and nuclear many-body theory. The m

We derive the leading contribution to the four--nucleon force within the framework of chiral effective field theory. It is governed by the exchange of pions and
