Evaluating the three-loop static quark potential

Understand

This is a status report of the evaluation of the three-loop corrections to the static QCD potential of a heavy quark and an antiquark.

• The families of Feynman integrals that appear in the evaluation are described.
• To reduce any integral of the families to master integrals we solve integration-by-parts relations by the algorithm called FIRE.
• To evaluate the corresponding master integrals we apply the Mellin-Barnes technique.
