Is QCD asymptotically free?
Abstract
Description
The asymptotical behaviour of the QCD coupling strength is considered. Its upper bound is found from the present experimental data. The assumption about the finite asymptotical value of the coupling strength leads to the energy scale where the perturbative predictions would fail. Possible tests of this assumption are considered.
