Abstract
The evaluation of the higher twist contributions to Deep Inelastic Scatteri ng amplitudes involves a non trivial choice of operator bases for the highe r orders of the OPE expansion of the two hadronic currents. In this talk we discuss the perturbative renormalization of the four-fermion operators tha t appear in the above bases.
