Title: Chiral Symmetry and the Nucleon-Nucleon Interaction

Journal Article · · Symmetry
DOI:https://doi.org/10.3390/sym8040026· OSTI ID:1419594

We review how nuclear forces emerge from low-energy quantum chromodynamics (QCD) via chiral effective field theory (EFT). During the past two decades, this approach has evolved into a powerful tool to derive nuclear two- and many-body forces in a systematic and model-independent way. We then focus on the nucleon-nucleon (NN) interaction and show in detail how, governed by chiral symmetry, the long- and intermediate-range of the NN potential builds up order by order. We proceed up to sixth order in small momenta, where convergence is achieved. Lastly, the final result allows for a full assessment of the validity of the chiral EFT approach to the NN interaction.
