dc.description.abstractThis Letter reports on the first computation, from data obtained in lattice QCD with u, d, s, and c quarks in the sea, of the running strong coupling via the ghost-gluon coupling renormalized in the momentum-subtraction Taylor scheme. We provide readers with estimates of ¿MS¯¯¯¯¯¯(m2¿) and ¿MS¯¯¯¯¯¯(m2Z) in very good agreement with experimental results. Including a dynamical c quark makes the needed running of ¿MS¯¯¯¯¯¯ safer.en_US
