In these notes we present a detailed and
complete scheme for the calculation of
polarization phenomena in elastic
electron-nucleon scattering. The
longitudinal and transversal components of the
polarization for the scattered nucleon,
induced by the scattering of longitudinally
polarized electrons and the asymmetries for
the collision of polarized electrons with a
polarized nucleon target are included. The
calculations are done in the framework of the
one-photon mechanism, in the Breit system,
which is the most convenient for the analysis
of polarization effects. We briefly discuss
the region of applicability of such model and
other mechanisms (radiative and electroweak
corrections) which
may come into this idealized picture. |
