Abstract:

We report on the status of the calculation of the massive Wilson coefficients and operator matrix elements for deep-inelastic scattering 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. Numerical results on the structure function F2(x,Q2)F2(x,Q2) are presented. In the polarized case, we work in the Larin scheme and refer to parton distribution functions in this scheme. Furthermore, results on the three-loop variable flavor number scheme are presented
