手征微扰理论与介子

Chiral Perturbation Theory and Mesons

Johan Bijnens

摘要:

讲座包含了对介子手征微扰理论(ChPT)的简短介绍。此外,还讨论了近年来取得一些进展的四个不同领域。这些是$p^4$阶低能常数$L_i^r$与数据的最后拟合,硬π ChPT,最近的两个循环的工作EFT类QCD理论和高阶领先的对数计算在大质量$O(N)$非线性西格玛模型。

英文摘要:

The talk contains a short introduction to mesonic Chiral Perturbation Theory (ChPT). In addition four disparate areas where some progress has been made in recent years are discussed. These are the last fit of the order $p^4$ low-energy-constants $L_i^r$ to data, hard pion ChPT, the recent two-loop work on EFT for QCD like theories and the high order leading logarithm calculations in the massive $O(N)$ nonlinear sigma model.
