Description
In this talk we discuss on recent result on massless and massive Wilson
coefficients in the polarized and unpolarized case up to 3-loop order.
This includes the gluonic massive operator matrix element $A_{gg}$
which enters the definition of the Variable-Falvor-Number-Scheme, and the
calculation of the unpolarized and polarized massless Wilson coefficients.
While the calculation of the unpolarized case is the first independent calculation
of these quantities, the result for $g_1$ is obtained for the first time and
is a necessary ingredient to obtain the polarized massive Wilson coefficients in
the asymptotic limit.
