QCD强耦合常数的非广延性

Non-Extensive Behaviour of the QCD Strong Coupling Constant

K. Javidan, M. M. Yazdanpanah, H. Nematollahi

摘要:

研究了用重整化群方法计算强耦合常数的理论值与实验值的相容性。在低能区,理论计算结果与实验结果之间存在较大的差异,不能用热场论和考虑化学势来解释。通过在理论结果与实验数据的拟合中加入一个q-非延拓参数,考虑q-广义统计效应,可以成功地处理这样大的偏差。

英文摘要:

The compatibility of theoretically calculated values for the strong coupling constant,through the renormalization group approach with experimental data is studied. There exist considerable divergence in-between theoretical and experimental results at low energies, which can not be explained by thermal field theory and considering chemical potential. Such great deviation can be treated successfully by considering the q-generalized statistical effects through adding a q-nonextensive parameter in the fitting of theoretical results on experimental data.
