摘要：

A non-perturbative finite-size scaling technique is used to study the evolution of the running coupling (in a certain adapted scheme) in the SU(3) Yang-Mills theory. At low energies contact is made with the fundamental dynamical scales, such as the string tension K, while at larger energies the couplings shown to evolve according to perturbation theory. In that regime the coupling in the MSBAR scheme of dimensional regularization is obtained with an estimated total error of a few percent.
