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