ABSTRACT

We study the effects of the virtuality of the nucleon on the pion-nucleon vertex, on the nucleon propagator and on the matrix element for low-energy pion-nucleon scattering. The vertex and propagator can be expressed in terms of the empiricalT=1/2,S1/2 andP1/2 πN phase-shifts. The influence of a resonance in the latter state is discussed. Pion scattering off a virtual nucleon is studied with the help of one-dimensional dispersion relations. The dependence of theT=J=3/2 partial-wave amplitude on the squared four-momentum of the virtual nucleon is so determined. More... »
