Effective chiral theory of nucleon-nucleon scattering
نویسنده
چکیده
We present a new chiral expansion scheme for the nucleon-nucleon scattering amplitude which preserves unitarity exactly. Our effective field theory builds on the power counting rules for 2-nucleon reducible diagrams proposed in [1]. We evaluate the leading order terms of the isospin one scattering amplitude and elaborate in detail on the S0 phase shift. Our chiral description of the S0phase shift does compete in quality with modern phenomenological nucleon-nucleon potentials. We describe elastic and inelastic scattering quantitatively up to laboratory energies of Elab ' 600 MeV.

Chiral Perturbation Theory
After a general introduction to the structure of effective field theories, the main ingredients of chiral perturbation theory are reviewed. Applications include the light quark mass ratios and pion–pion scattering to two–loop accuracy. In the pion–nucleon system, the linear σ model is contrasted with chiral perturbation theory. The heavy–nucleon expansion is used to construct the effective pion...
متن کاملHyperon-nucleon interactions in effective field theory
Abstract. We have constructed the leading order hyperon-nucleon potential in a chiral Effective Field Theory approach. The chiral potential consists of one-pseudoscalar-meson exchanges and non-derivative four-baryon contact terms. The hyperon-nucleon interactions are derived using SU(3) symmetry, the nucleon-nucleon interaction is not considered explicitly since it can not be described well wit...
متن کاملChiral nucleon dynamics
These lectures give an introduction to baryon chiral perturbation theory. I show in detail how to construct the chiral effective pion–nucleon Lagrangian in the one loop approximation. Particular emphasis is put on the physics related to electromagnetic probes, as manifest in pion photo– and electroproduction, Compton scattering off nucleons and the electroweak form factors of the nucleon. Other...

Information obtained from nucleus as a bound system of nucleons and from nucleon-nucleon scattering experiments is a strong tool for studying various aspects of nuclear forces. Deuteron-deuteron scattering as a four-nucleon system can provide useful information. So, scattering experiment of a polarized beam of deuteron with kinetic energy of65 MeV/nucleon from a liquid-deuterium target was done...
متن کاملChiral dynamics in few–nucleon systems
We report on recent progress achieved in calculating various few–nucleon low–energy observables from effective field theory. Our discussion includes scattering and bound states in the 2N, 3N and 4N systems and isospin violating effects in the 2N system. We also establish a link between the nucleon–nucleon potential derived in chiral effective field theory and various modern high–precision poten...
