Abstract
The cross section for with
arbitrary
electron polarizations is calculated within the Electroweak Standard
Model for energies large compared to the electron mass, including the
complete virtual and soft-photonic radiative corrections.
The relevant analytical results are listed, and a numerical evaluation
is presented for the unpolarized and polarized cross sections as well
as for polarization asymmetries. The relative weak corrections are
typically of the order of 10%.
At low energies, the bulk of the
corrections is due to the running of the electromagnetic coupling
constant.
For left-handed electrons, at high energies the vertex and box
corrections involving virtual W bosons become very important.
The
polarization asymmetry is considerably reduced by the weak radiative
corrections.
