THE HARD BREMSSTRAHLUNG PROCESS E-GAMMA-]W-NU-E-GAMMA

Using the Weyl-van der Waerden formalism the helicity amplitudes for e- gamma --> W- nu(e)gamma are calculated for non-collinearly emitted photons. The extension of these amplitudes to collinear photon emission is discussed in detail. Numerical results are presented for energies ranging from threshold up to 2 TeV both for the polarized and unpolarized cross sections. Combining the bremsstrahlung and virtual corrections we find O(alpha) corrections to e- gamma --> W- nu(e) of typically several percent which are more enhanced near threshold and for higher energies.
