Chiral nucleon dynamics

چکیده
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 topics discussed in some detail are the meaning of low–energy theorems, pion–nucleon scattering, the reaction πN → ππN and isospin violation in the pion–nucleon system. The chiral predictions are confronted with the existing data. Some remaining problems and new developments are outlined. Lectures given at The Hampton Graduate Studies at Jefferson Lab (HUGS 97) Newport News, Virginia, USA, June 1997 KFA-IKP(TH)-97-20 November 1997

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...
