论文摘要
我们简要介绍了dyson-Schwinger方程(DSE)的强子和高能物理学方法。特别是,如何应用这种形式主义来计算电磁形式因子$γ^*γ^* \ to \ textbf {p}^0 $和$γ^* \ textbf {p}^\ pm \ to \ textbf {p}分别讨论了带电和中性的基态伪级介子)。随后,估计了这些形式因素对MUON异常磁矩($ G-2 $)的相应贡献。我们期待促进DSE方法来解决MUON $ G-2 $的理论方面,并强调了将来可以进行的一些计算。
We present a brief introduction to the Dyson-Schwinger equations (DSEs) approach to hadron and high-energy physics. In particular, how this formalism is applied to calculate the electromagnetic form factors $γ^* γ^* \to \textbf{P}^0$ and $γ^* \textbf{P}^\pm \to \textbf{P}^\pm$ (with $\textbf{P}^\pm$ and $\textbf{P}^0$ charged and neutral ground-state pseudoscalar mesons, respectively) is discussed. Subsequently, the corresponding contributions of those form factors to the muon anomalous magnetic moment ($g-2$) are estimated. We look forward to promoting the DSE approach to address theoretical aspects of the muon $g-2$, highlighting some calculations that could be carried out in the future.
