Heavy Flavor Contributions to DIS Structure Functions at $O({\alpha }_s^3)$

Isabella Bierenbaum, Johannes Blümlein, Sebastian Klein

We calculate moments of the $O({\alpha }_s^3)$ heavy flavor contributions to the Wilson coefficients of the structure function $F_2(x,Q^2)$ in the region $Q^2\gg m^2$. The massive Wilson c…
