NLO corrections for the dipole factorization of DIS structure functions at low x

Abstract

The NLO generalization of the dipole factorization formula for the structure functions F_2 and F_L at low x is calculated using light front perturbation theory. That result gives some interesting insight into the kinematics of initial state parton showers in mixed space.
