AB We report on the first computation of the strong running coupling at the physical point (physical pionmass) from the ghost-gluon vertex, computed from lattice simulations with three flavors of domain wallfermions. We find  MSðm2ZÞ ¼ 0.1172ð11Þ, in remarkably good agreement with the world-wide average.Our computational bridge to this value is the Taylor-scheme strong coupling, which has been revealed ofgreat interest by itself because it can be directly related to the quark-gluon interaction kernel in continuumapproaches to the QCD bound-state problem.
