The compatibility of theoretically calculated values for \(\alpha _s(Q)\), through the renormalization group approach with experimentally determined data is studied. We consider the q-generalized statistical effects through adding a q-non extensive 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.

低能量时的QCD强耦合常数:非广泛处理

研究了通过重归一化组方法对\(\ alpha _s(Q)\)的理论计算值与实验确定的数据的兼容性。我们通过在强耦合常数的实验数据的理论结果的拟合中添加q非广义参数来考虑q广义统计效应。与零温度和热场理论相比,即使考虑化学势和温度,我们在低能量下的结果也显示出更合适的处理方法。
