The Two-mass Contribution to the Three-Loop Polarized Operator Matrix Element $A_{gg,Q}^{(3)}$

J. Ablinger, J. Blümlein, A. De Freitas +4

We compute the two-mass contributions to the polarized massive operator matrix element $A_{gg,Q}^{(3)}$ at third order in the strong coupling constant ${\alpha }_s$ in Quantum Chromodynami…
