The Schroedinger functional coupling in quenched QCD at low energies
arXiv:hep-lat/0110201 · doi:10.1016/S0920-5632(01)01867-9
Abstract
Existing non-perturbative computations of the running coupling of quenched QCD in the Schroedinger functional scheme are extended to scales mu lying much deeper in the low-energy regime. We are able to reach 1/mu ~ 0.9 fm, where a significant deviation from its perturbative evolution is observed.
