The Wilson Coefficients of Heavy Quark Production in Charged Current DIS in Mellin and x-Space to O(α_s²) — •Alexander Hasselhuhn, Johannes Blümlein, and Fabian Wißbrock — DESY, Zeuthen

The charged current heavy flavor Wilson coefficients to first and second order in the strong coupling constant are computed for large momentum transfer.

At leading order, also the power corrections in (m²/Q²) are given. We derive representations in x- and Mellin-space for phenomenological analyses. These are of importance for the extraction of the strange quark distribution functions and allow for an efficient analysis of the DIS charged current world data.
