Massive quarks in NLO dipole factorization for DIS: Transverse photon

We calculate the light-cone wave functions for QCD Fock components in a transverse virtual photon necessary applications at next-to-leading order (NLO) coupling, including quark masses. present detailed calculation of both one-loop function quark-antiquark component and tree-level quark-antiquark-gluon component. The masses are renormalized pole mass scheme, satisfying constraints from requirement Lorentz invariance. In particular Pauli form factor NLO is recovered on-shell limit use our result to next-to-leading-order correction high energy deep inelastic scattering (DIS) structure on dense target dipole factorization framework. Together with earlier longitudinal photons, this completes total cross section picture massive quarks order, enabling comparison experimental data.
