Radiative effects in scattering of polarized leptons by polarized nucleons and light nuclei
Recent developments in the field of radiative effects in polarized
lepton-nuclear scattering are reviewed. The processes of inclusive,
semi-inclusive, diffractive and elastic scattering are considered. The explicit
formulae obtained within the covariant approach are discussed. FORTRAN codes
POLRAD, RADGEN, HAPRAD, DIFFRAD and MASCARAD created on the basis of the
formulae are briefly described. Applications for data analysis of the current
experiments on lepton-nuclear scattering at CERN, DESY, SLAC and TJNAF are
illustrated by numerical results.Comment: 39 pages, 12 figures, contribution to Lepton-Photon 0
Radiative corrections to the lepton current in unpolarized elastic -interaction for fixed and scattering angle
The kinematical difference between the description of radiative effects for
fixed vs a fixed scattering angle in the elastic lepton-proton
()-scattering is discussed. The technique of calculation as well as
explicit expressions for radiative corrections to the lepton current in
unpolarized elastic -scattering for these two cases are presented without
using an ultrarelativistic approximation. A comparative numerical analysis
within kinematic conditions of Jefferson Lab measurements and MUSE experiment
in PSI is performed.Comment: 12 pages, 5 figures, published in European Physical Journal A Topical
