Abstract

We report on results for the heavy flavor contributions to F2(x,Q2)F_2(x,Q^2) in the limit Q2m2Q^2\gg m^2 at {\sf NNLO}. By calculating the massive 33--loop operator matrix elements, we account for all but the power suppressed terms in m2/Q2m^2/Q^2. Recently, the calculation of fixed Mellin moments of all 33--loop massive operator matrix elements has been finished. We present new all--NN results for the O(nf)O(n_f)--terms, thereby confirming the corresponding parts of the 33--loop anomalous dimensions. Additionally, we report on first genuine 33--loop results of the ladder--type diagrams for general values of the Mellin variable NN.
