Pion Electroproduction Off The Deuteron

📕 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.
