Abstract
We calculate the massive Wilson coefficients for the heavy-flavor contributions to the nonsinglet charged-current deep-inelastic scattering structure function in the asymptotic region to three-loop order in QCD at general values of the Mellin variable and the momentum fraction . Besides the heavy-quark pair production also the single heavy-flavor excitation contributes. Numerical results are presented for the charm-quark contributions and consequences on the Gross-Llewellyn Smith sum rule are discussed.
