Charged current deep-inelastic scattering at three loops Original Research Article

We derive for deep-inelastic neutrino(ν)–proton(P) scattering in the combination image the perturbative QCD corrections to three loops for the charged current structure functions image, image and image. In leading twist approximation we calculate the first five odd-integer Mellin moments in the case of image and image and the first five even-integer moments in the case of image. As a new result we obtain the coefficient functions to image while the corresponding anomalous dimensions agree with known results in the literature.
