This review discusses how nuclear forces emerge from low-energy quantum chromodynamics (QCD) through chiral effective field theory (EFT). The article provides an accessible introduction to the topic for non-specialists while also offering detailed information for researchers interested in the field. It covers the symmetries of low-energy QCD, including chiral symmetry, explicit symmetry breaking, and spontaneous symmetry breaking. The paper explains the construction of chiral effective Lagrangians, both in relativistic and heavy baryon formalisms, and discusses the hierarchy of nuclear forces. It details two-nucleon interactions, including pion-exchange contributions, and explores the role of contact terms in nuclear forces. The article also addresses nuclear many-body forces, three-nucleon forces, and four-nucleon forces. It introduces Δ-isobar degrees of freedom and discusses the construction of quantitative chiral nuclear potentials. The paper concludes with a summary of the key findings and highlights the importance of chiral symmetry in understanding nuclear forces. The review emphasizes the use of chiral effective field theory to describe nuclear forces from low-energy QCD, providing a framework for understanding the dynamics of nuclear interactions.This review discusses how nuclear forces emerge from low-energy quantum chromodynamics (QCD) through chiral effective field theory (EFT).
