摘要：We report on recent results obtained for the massive Wilson coefficients which contribute to the structure function F2(x,Q2) at O(a3 s ) in the region Q2/m2> ∼ 10. In the calculation new species of harmonic sums and harmonic polylogarithms generated by cyclotomic polynomials arise in intermediary results which are briefly discussed.
