We report on the status of the calculation of the massive Wilson coefficients and operator matrix elements for deep-inelastic scatterung to three-loop order. We discuss both the unpolarized and the polarized case, for which all the single-mass and nearly all two-mass contributions have been calculated [...]

/ Blümlein, Johannes (DESY, Zeuthen) ; Behring, Arnd (DESY, Zeuthen ; CERN) ; Goedicke, Alexander (DESY, Zeuthen ; Linz U.) ; von Manteuffel, Andreas (Regensburg U. ; Michigan State U.) ; Schneider, Carsten (Linz U.) ; Schönwald, Kay (DESY, Zeuthen ; Zurich U.) ; Ablinger, Jakob (Linz U.) ; De Freitas, Abilio (DESY, Zeuthen ; Linz U.)
We report on recent progress in calculating the three loop QCD corrections of the heavy flavor contributions in deep--inelastic scattering and the massive operator matrix elements of the variable flavor number scheme. Notably we deal with the operator matrix elements $A_{gg,Q}^{(3)}$ and $A_{Qg}^{(3)}$ and technical steps to their calculation. [...]

The first-order factorizable contributions to the three-loop massive operator matrix elements $A_{Qg}^{(3)}$ and $\Delta A_{Qg}^{(3)}$
/ Ablinger, J. (Linz U. ; OAW, Linz, RICAM) ; Behring, A. (CERN ; DESY, Zeuthen) ; Blümlein, J. (DESY, Zeuthen) ; De Freitas, A. (Linz U. ; DESY, Zeuthen) ; von Manteuffel, A. (Regensburg U. ; Michigan State U.) ; Schneider, C. (Linz U.) ; Schönwald, K. (Zurich U.)
The unpolarized and polarized massive operator matrix elements $A_{Qg}^{(3)}$ and $\Delta A_{Qg}^{(3)}$ contain first-order factorizable and non-first-order factorizable contributions in the determining difference or differential equations of their master integrals. We compute their first-order factorizable contributions in the single heavy mass case for all contributing Feynman diagrams. [...]

The unpolarized and polarized single-mass three-loop heavy flavor operator matrix elements A$_{gg,Q}$ and ∆A$_{gg,Q}$
/ Ablinger, J. (Linz U., RISC) ; Behring, A. (DESY, Zeuthen ; CERN) ; Blümlein, J. (DESY, Zeuthen) ; De Freitas, A. (Linz U., RISC ; DESY, Zeuthen) ; Goedicke, A. (DESY, Zeuthen) ; von Manteuffel, A. (Michigan State U.) ; Schneider, C. (Linz U., RISC) ; Schönwald, K. (DESY, Zeuthen ; Zurich U.)
We calculate the gluonic massive operator matrix elements in the unpolarized and polarized cases, $A_{gg,Q}(x,\mu^2)$ and $\Delta A_{gg,Q}(x,\mu^2)$, at three-loop order for a single mass. These quantities contribute to the matching of the gluon distribution in the variable flavor number scheme. [...]
