A bstract In the target fragmentation region of Semi-Inclusive Deep Inelastic Scattering, diffractively produced hadron has small transverse momentum. If it is at order Λ QCD , prevents to make predictions with standard collinear factorization. However, in this case, differential cross-sections can be predicted by factorization fracture functions, diffractive parton distributions. momentum much larger than but smaller Q which virtuality virtual photon, both factorizations apply. functions factorized distributions and functions. We study up twist-3 level obtain gauge invariant results. They will helpful for modeling useful resummation large logarithm appearing
