A consistent and intuitive description of the twist-4 corrections to the hadron structure functions is presented in a QCD-improved parton model using timeordered perturbative theory, where the collinear singularities are naturally eliminated. We identify the special propagators with the backward propagators of partons in time order. PACS numbers: 12.38.Bx… CONTINUE READING
