Abstract
The compatibility of theoretically calculated values for αs(Q), through the renormalization group approach with experimentally determined data is studied. We consider the q-generalized statistical effects through adding a q-nonextensive parameter in the fitting of theoretical results on experimental data of the strong coupling constant. Our results at low energies show more appropriate treatment in comparison with those of zero temperature and thermal field theory even by considering the chemical potential and temperature.
