交错手征微扰理论的新进展

Recent progress in staggered chiral perturbation theory

Jon Bailey, Hyung-Jin Kim, Weonjong Lee, Boram Yoon

摘要:

本文综述了交错手征微扰理论的最新进展。在过去的十年中,SChPT的应用范围已经超出了校准水平,进入高精度预测区域。SChPT成为对改进的交错费米子计算的物理观测值进行可靠的数据分析的重要工具。在这里,我们集中在以下的例子:π介子光谱,π介子衰变常数,$\varepsilon_K$,和$π-π$散射振幅。在每个主题中,我们回顾了最近的进展和未来的展望。

英文摘要:

We present a review on recent progress in staggered chiral perturbation theory (SChPT). In the last decade, the scope of the application of SChPT has been extended beyond the level of calibration into the region of prediction with high precision. SChPT becomes an essential tool to do the data analysis reliably for physical observables calculated using improved staggered fermions. Here, we focus on the following examples: pion spectrum, pion decay constants, $\varepsilon_K$, and $π-π$ scattering amplitudes. In each subject, we review the recent progress and future prospects.
