The Complete Os2) Pure-Singlet Heavy Flavour Corrections to the Unpolarized and Polarized Deep-Inelastic Structure FunctionsJohannes Blümlein1, Abilio De Freitas1, Clemens Raab2, and •Kay Schönwald11DESY, Zeuthen — 2Johannes Kepler Universität, Linz

We calculate analytically the flavour pure-singlet O(αs2) massive Wilson coefficients for the inclusive structure functions F2, FL and g1 at general virtualities Q2 in the deep-inelastic region. We discuss their functional representation, illustrate their large-scale factorization and threshold-representation, and present numerical results.
