## New Heavy Flavor Contributions to the DIS Structure Function $F_2(x,Q^2)$ at $O(α_s^3) [PDF] J. Ablinger, J. Blümlein, A. Hasselhuhn, S. Klein, C. Schneider, F. Wißbrock We report on recent results obtained for the massive Wilson coefficients which contribute to the structure function$F_2(x,Q^2)$at$O(\alpha_s^3)$in the region$Q^2/m^2 \gsim 10\$. In the calculation new species of harmonic sums
and harmonic polylogarithms generated by cyclotomic polynomials arise in
intermediary results which are briefly discussed.
