Abstract
The box diagram of virtual photon-nucleon scattering is analyzed for spin 1/2 parton in the covariant parton model. Due to the off-shell-ness of parton, the calculated cross section ratio σL/σT and the primordial transverse momentum are large enough to explain the data, which removes the difficulties in the ξ-scaling theory (the on-shell formalism).Keywords
