The unpolarized and polarized single-mass three-loop heavy flavor operator matrix elements A$_{gg,Q}$ and ∆A$_{gg,Q}$
We calculate the gluonic massive operator matrix elements in the unpolarized and polarized cases, A$_{gg,Q}$(x, μ$^{2}$) and ∆A$_{gg,Q}$(x, μ$^{2}$), at three-loop order for a single mass. These quantities contribute to the matching of the gluon distribution in the variable flavor number scheme. The...
