Description
In this presentation I would like to discuss technical and computational problems on
the derivation of the perturbative QCD corrections to three loops for the charged
current structure functions F_2, F_L and F_3 for deep-inelastic neutrino-proton
scattering in the combination "nu P - nubar P". In leading twist approximation we
calculate the first six odd-integer Mellin moments in the case of F_2 and F_L and the
first five even-integer moments in the case of F_3 . As a new result we obtain the
coefficient functions to O(alpha_s^3) while the corresponding anomalous dimensions
agree with known results in the literature.
