从QCD的基本理论计算p6阶手征拉格朗日系数

Computation of the p6 order chiral Lagrangian coefficients from the underlying theory of QCD

Shao-Zhou Jiang, Ying Zhang, Chuan Li, Qing Wang

摘要:

本文给出了两味和三味赝标介子手征拉格朗日正规部分p6阶低能常数的计算结果。这是我们以前用夸克自能σ(p2)近似地从QCD计算手征拉格朗日量p4阶系数的工作的推广。我们表明,我们的大部分结果是一致的,我们可以在文献中找到。

英文摘要:

We present results of computing the p6 order low energy constants in the normal part of chiral Lagrangian both for two and three flavor pseudo-scalar mesons. This is a generalization of our previous work on calculating the p4 order coefficients of the chiral Lagrangian in terms of the quark self energy Sigma(p2) approximately from QCD. We show that most of our results are consistent with those we can find in the literature.
