Hard-Photon Emission in High Energy e Scatterings

Abstract
Bremsstrahlung of hard-photon in high energy νe scatterings is studied in the Weinberg-Salam theory. The hard-photon cross sections, σ(νμe → νμ), σ(νμe → νμe γ) and σ(νμe → μνe γ), are found to be large and almost cancel the virtual and soft photon effects. The total electromagnetic 1-loop corrections to the Born cross sections are small, about −(1 ∼2)%.
