Book Description
This work is the first step of a systematic study of incoherent electroproduction of pion mesons off the deuteron in the (1232) resonance region, it is taken by restriction to the impulse approximation, i.e., neglecting pion rescattering and two-body effects. The elementary operator for pion electroproduction from the nucleon is taken from the unitary isobar model (MAID) which is a model for single pion photo- and electroproduction off protons and neutrons. This approximation corresponds to the so-called spectator model in which the pion production takes place on a single nucleon inside the deuteron while the other nucleon acts merely as a spectator.

Book Description
The objective of this talk is to review the recent theoretical developments in the study of photo- and electro-production of pions on the nucleon. First, the author will discuss the results from the investigations in the near threshold region. The focus here is the test of pion dynamics as predicted by the theoretical models with chiral symmetry. The second subject of this talk is concerned with the deformation of the Delta ([Delta]) state. The central question here is how this interesting quantity is defined theoretically and related to the experiments being performed at MIT-Bates and Mainz. The author then will discuss briefly the higher energy region where the productions of higher mass nucleon resonances (N*) and two-pion states become important. The interest here is the test of [gamma]N [yields] N* matrix elements as predicted by various QCD-based models of hadrons.
