Abstract
We report on results for the heavy flavor contributions to F2(x,Q2) in the limit Q2â«m2 at NNLO. By calculating the massive 3-loop operator matrix elements, we account for all but the power suppressed terms in m2/Q2. Recently, the calculation of fixed Mellin moments of all 3-loop massive operator matrix elements has been finished. We present new all-N results for the O(nf)-terms, thereby confirming the corresponding parts of the 3-loop anomalous dimensions. Additionally, we report on first genuine 3-loop results of the ladder-type diagrams for general values of the Mellin variable N.
