Off-shell Electromagnetic Form Factors of the Nucleon in Chiral Perturbation Theory
نویسنده
چکیده
We study the electromagnetic form factors of a nucleon in next-to-leading order chiral perturbation theory (CPT) in the case where one of the nucleons is off its mass shell. We calculate the leading nonanalytic contributions to relevant measures for the off-shell dependence in the limited kinematical range allowed.

The off-shell electromagnetic vertex of the nucleon in chiral perturbation theory
We study the electromagnetic vertex of a nucleon in next-to-leading order chiral perturbation theory (CPT). We consider the case where one of the nucleons at the γNN vertex is off its mass shell. We define relevant measures for the off-shell dependence in the limited kinematical range allowed, and analyze their expansion in the pion mass. The leading nonanalytic contributions are calculated to ...
متن کاملOff-shell electromagnetic form factors of pions and kaons in chiral perturbation theory.
The off–shell electromagnetic vertex of a (pseudo–) scalar particle contains, in general, two form factors F and G which depend, in addition to the squared momentum transfer, on the invariant masses associated with the initial and final legs of the vertex. Chiral perturbation theory to one loop is used to calculate the off–shell form factors of pions and kaons. The formalism of Gasser and Leutw...

We briefly outline the so-called extended on-mass-shell renormalization scheme for manifestly Lorentz-invariant baryon chiral perturbation theory which provides a simple and consistent power counting for renor-malized diagrams. We comment on the role of chiral symmetry in the renormalization program and discuss as applications the mass and the electromagnetic form factors of the nucleon.

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...
متن کاملBaryon chiral perturbation theory
We provide an introduction to the power-counting issue in baryon chiral perturbation theory and discuss some recent developments in the manifestly Lorentz-invariant formulation of the one-nucleon sector. As explicit applications we consider the chiral expansion of the nucleon mass, its convergence properties, and calculations of the electromagnetic and axial form factors of the nucleon.
