The non-first-order-factorizable contributions to the three-loop single-mass operator matrix elements A^(3)_Qg and ∆A^(3)_Qg
ons to the unpolarized and polarized massive operator matrix elements to three-loop order, A(3) Qg and ∆A(3) Qg, are calculated in the single- mass case. For the 2F1-related master integrals of the problem …
