Heavy Flavor DIS Wilson coefficients in the asymptotic regime

Abstract

We report on results for the heavy flavor contributions to F(2)(x, Q(2)) in the limit Q(2) >> m(2) at NNLO. By calculating the massive 3 loop operator matrix elements, we account for all but the power suppressed terms in m(2)/Q(2). 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(n(f)) 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.
