O(αs) heavy flavor corrections to charged current deep inelastic scattering in Mellin space

We provide a fast and precise Mellin space implementation of the O(αs) heavy flavor Wilson coefficients for charged current deep inelastic scattering processes. They are of importance for the extraction of the strange quark distribution in neutrino-nucleon scattering and the QCD analyses of the HERA charged current data. Errors in the literature are corrected. We also discuss a series of more general parton parameterizations in Mellin space.
