Chiral effective field theory for few–nucleon systems
Chiral Effective Field Theory (EFT) has become a standard tool for analyzing the properties of hadronic systems at low energy where the perturbative expansion of Quantum Chromodynamics (QCD) in powers of the coupling constant cannot be applied, see [1,2]. It is based upon the approximate and spontaneously broken chiral symmetry of QCD. Starting from the most general effective Lagrangian for Gol...
متن کاملAn Introduction to Few Nucleon Systems in Effective Field Theory
Progress in the Effective Field Theory of two and three nucleon systems is sketched, concentrating mainly on the low energy version in which pions are integrated out as explicit degrees of freedom. Examples given are: the extraction of nucleon polarisabilities from deuteron Compton scattering at very low energies; the energy dependence of the nucleon polarisabilities; three body forces and the ...
متن کاملEffective Field Theory and Isospin Violation in Few–Nucleon Systems
I discuss the leading and subleading isospin–breaking three–nucleon forces in the chiral effective field theory framework. INTRODUCTION Isospin violation has its origin within the Standard Model in the different masses of the up and down quarks and electromagnetic interaction. Its consequences for few–nucleon systems can be studied in a systematic way within chiral Effective Field Theory (EFT)....
متن کاملFew–Nucleon Forces and Systems in Chiral Effective Field Theory
We outline the structure of the nuclear force in the framework of chiral effective field theory of QCD and review recent applications to processes involving few nucleons.
متن کاملFew-Body Systems and the Pionless Effective Field Theory
The pionless effective field theory (EFT) is the appropriate low-energy EFT for short-range interactions that display a large scattering length. It has been successfully applied in atomic, nuclear and particle physics. We give an overview over recent calculations employing the pionless effective field theory and lay emphasis on applications in the threeand four-body sector where the most exciti...
