Electromagnetic form factors of the nucleon in the few GeV region

  • Published:
Zeitschrift für Physik A Hadrons and Nuclei

Abstract

The form factors of the nucleon are investigated in a framework in which nucleons are viewed as built up by quarks and diquarks, the latter being treated as quasie-lementary constituents. This model is a generalization of the hard scattering scheme for exclusive reactions applicable at moderately large momentum transfer. In contrast to the hard scattering scheme the diquark model provides non-zero helicity flip transitions of the nucleon. Therefore, we obtain predictions for both the magnetic and the electric form factor. The results are in good agreement with data.
