摘要

本文报道了$SU(3)$ $N_f=8$ LSD谱数据与具有扩张介子的手性微扰理论的拟合。这些拟合证实，目前的模拟处于“大质量”状态，近似的超大尺度是主要的质量依赖。我们发现，序有效场论很好地描述了数据。特别是，有效场理论使我们能够理解交错的味觉分裂，解释在LSD数据中观察到的模式，这看起来与QCD不同。

Fits of SU(3) $N_f=8$ data to dilaton-pion effective field theory

We report on fits of the $SU(3)$ $N_f=8$ LSD spectral data to chiral perturbation theory with a dilatonic meson. These fits confirm that current simulations are in the "large-mass" regime, with approximate hyperscaling as the leading mass dependence. We find that the leading-order effective field theory describes the data well. In particular, the effective field theory allows us to understand the staggered taste splitting, explaining the pattern observed in the LSD data, which looks different from QCD.
