Description

We report on recent results obtained for the 3-loop heavy flavor Wilson coefficients in deep-inelastic scattering at general values of the Mellin variable N at large scales of Q^2. These concern contributions to the gluonic ladder-topologies, the transition matrix elements in the variable flavor scheme, and first results on higher topologies. The knowledge of the heavy flavor Wilson coefficients in 3-loop order is of importance to carry out complete NNLO QCD analyses of the world precision data on the structure function F_2(x,Q^2).
