Two Loop Massive Operator Matrix Elements and Heavy Flavor Production in Deep-Inelastic Scattering — •Sebastian Klein, Isabella Bierenbaum, and Johannes Blümlein — DESY-Zeuthen, Platanenallee 6, 15738 Zeuthen

We calculate the 2-loop Wilson coefficients for heavy flavor production in the kinematic region Q^2 >> m^2. The method of massive operator matrix elements is used. We present a new evaluation method based on generalized hypergeometric functions and Mellin-Barnes integrals. Analytic results are presented in terms of harmonic sums and their analytic continuation.
