Pion–Pion and Pion–Nucleon Interactions in Chiral Perturbation Theory*
Elastic pion–pion and pion–nucleon scattering are reviewed in the context of chiral perturbation theory. Theoretical results from systematic low–energy expansions to O(p) for ππ and to O(p) for πN are compared with experimental data. Possible future developments are outlined. Talk given at the Workshop on Chiral Dynamics 1997 Mainz, Germany, Sept. 1 5, 1997 To appear in the Proceedings * Work s...
متن کاملSingle Pion Production Process in Pion - Nucleon Collision and the Sakata Model
Based on the Sakata model, we propose a model for the single pion production process in n-N collision which is essentially an extension of the Lindenbaum-Sternheimer model. It is pointed out that the analyses of sub-Bev single pion production phenomena will give us useful information about the level scheme of the Sakata Model. As a first step of the investigation of this model an analysis of th...
متن کاملEffect of Pion-Pion Scattering Resonance on Nucleon Structure and Pion-Nucleon Scattering at Low Energies
The effect of pion-pion scattering resonance on the isovector part of nucleon structure is analysed by a method similar to that of Frazer and Fulco, but with one more subtraction for dispersion relations on helicity amplitudes of nucleon·aritinucleon production process in order to remedy the divergence regarding the left-hand cut. If the subtracted spectral representations are used for the form...
متن کاملTheoretical Aspects of the Pion-pion Interaction
The structure of the ππ interaction at low energies is strongly constrained by the fact that the pion is the Goldstone boson of a spontaneously broken approximate symmetry of QCD.1 The scattering amplitude can be calculated in a systematic way in the framework of Chiral Perturbation Theory (ChPT),2 by an expansion which converges very rapidly near the center of the Mandelstam triangle. However,...
متن کاملMicroscopic derivation of pion-nucleon and pion-Delta scattering lengths
A general expression for the π − N and π − ∆ scattering lengths is derived in the framework of a microscopic calculation. Annihilation, negative energy wavefunctions and spontaneous chiral symmetry are included consistently. The point-like limit is used to calculate the scattering lengths.
