Hidden scale dependence in renormalon
Abstract
In the framework of renormalon consideration, a role of the anomalous dependence of gluon propagator on the scale μ is shown for a large number of quark flavours as well as in the nonabelian theory, where the parameter of the "running" coupling constant evolution has a hidden dependence on the scale. A phenomenological matching between the modified renormalon and the static quark potential is described to fix the renormalon scales.
