Lowest order QED radiative effects in polarized SIDIS

Understand

The explicit exact analytical expressions for the lowest-order radiative corrections to the semi-inclusive deep inelastic scattering of the polarized particles are obtained in the most compact, covariant form convenient for the numerical analysis.

• The infrared divergence from the real photon emission is extracted and cancelled using the Bardin-Shumeiko approach.
• The contribution of the exclusive radiative tail is presented.The analytic results obtained within the ultrarelativistic approximation are also show.
