The unpolarized and polarized single-mass three-loop heavy flavor operator matrix elements A gg,Q and ∆A gg,Q

Abstract 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 pola...
