On the Evolution Kernels of Twist 2 Light-Ray Operators for Unpolarized and Polarized Deep Inelastic Scattering

High Energy Physics - Phenomenology 2010-03-25 v2

Abstract

The non-singlet and singlet evolution kernels of the twist--2 light-ray operators for unpolarized and polarized deep inelastic scattering are calculated in O(αs)O(\alpha_s) for the general case of virtualities q2,q20q^2, q'^2 \neq 0. Special cases as the kernels for the general single-variable evolution equation and the Altarelli-Parisi and Brodsky-Lepage limits are derived from these results.
