The Two-Nucleon System beyond the Pion Threshold
نویسنده
چکیده
A model is developed for the hadronic and electromagnetic interaction in the two-nucleon system above pion threshold in the framework of meson, nucleon and ∆ degrees of freedom. It is based on time-ordered perturbation theory and includes full meson retardation in potentials and exchange currents as well as loop contributions to the nucleonic one-body current. Results for some selected processes are discussed.

Photon- and pion-nucleon interactions in a unitary and causal effective theory
In recent years photonand pion-nucleon interactions have been successfully used as a quantitative challenge of chiral perturbation theory (χPT), which is a systematic tool to learn about low-energy QCD dynamics [1]. The application of χPT is however limited to the near threshold region. A method to extrapolate χPT results beyond the threshold region using analyticity and unitarity constraints w...
متن کاملPion-nucleon amplitude near threshold: the sigma-term and scattering lengths beyond few loops
The pion-nucleon amplitude is considered in the vicinity of the elastic scattering threshold within a relativistic dynamical model dressing the πNN and πN∆ vertices self-consistently with an infinite number of meson loops. The dressing is formulated as solution of a system of coupled integral equations incorporating unitarity, crossing symmetry and analyticity constraints. The calculated scatte...
متن کاملThree-Nucleon Force and the ∆-Mechanism for Pion Production and Pion Absorption
The description of the three-nucleon system in terms of nucleon and ∆ degrees of freedom is extended to allow for explicit pion production (absorption) from single dynamic ∆ de-excitation (excitation) processes. This mechanism yields an energy dependent effective three-body hamiltonean. The Faddeev equations for the trinucleon bound state are solved with a force model that has already been test...
متن کاملOn the Nucleon Renormalization in Many Nucleon Problems Due to Pionic Degrees of Freedom+
Conceptual problems of unified two-nucleon force models are discussed. The force models are based on the pion-nucleon vertex and attempt a description of the nucleon-nucleon interaction below and above pion threshold. The conceptual problems arise from the nucleon renormalization due to pionic degress of freedom. Keeping channels with a single pion only no renormalization procedure can be given...
متن کاملSoft Pion Emission from the Nucleon Induced by Twist-2 Light-Cone Operators
We compute the matrix elements for pion emission from the nucleon induced by twist-two light-cone operators in the kinematics where the pion is close to threshold. It is shown that the results of heavy baryon ChPT are in agreement with the results from the soft-pion theorem approach. Therefore the amplitude of soft-pion emission is directly related to the generalized parton distributions in the...
