The polarized transition matrix element Agq(N) of the variable flavor number scheme at O(αs3)

The polarized transition matrix element Agq(N) of the variable flavor number scheme at O(αs3)

We calculate the polarized massive operator matrix element Agq(3)(N) to 3-loop order in Quantum Chromodynamics analytically at general values of the Mellin variable N both in the single- and double-mass case in the Larin scheme. It is a transition function required in the variable flavor number sche...
