Chiral Effective Field Theory (EFT) is a theoretical framework used in nuclear and particle physics to describe low-energy interactions of nucleons and pions based on symmetries like chiral symmetry. It incorporates both the principles of quantum chromodynamics and chiral symmetry breaking, allowing for a systematic and model-independent approach to calculating observables in systems with spontaneously broken symmetries. Chiral EFT has been successful in describing a wide range of phenomena, including nuclear forces, few-body systems, and low-energy reactions, and has applications in both theoretical and experimental research in nuclear and particle physics.
