In previous work, [arXiv:1905.01909], we have calculated the mϱ/fπ ratio in the chiral and continuum limit for SU(3) gauge theory coupled to Nf = 2, 3, 4, 5, 6 fermions in the fundamental representation. The main result was that this ratio displays no statistically significant Nf-dependence. In the present work we continue the study of the Nf-dependence by extending the simulations to Nf = 7, 8, 9, 10. Along the way we also study in detail the Nf-dependence of finite volume effects on low energy observables and a particular translational symmetry breaking unphysical, lattice artefact phase specific to staggered fermions.

A preprint version of the article is available at ArXiv.

有关 mϱ/fπ 的风味依赖性的更多信息

在之前的工作 [arXiv:1905.01909] 中,我们已经计算了SU(3) 规范理论的手征和连续谱极限中的m ϱ /fπ比,该比与N f = 2 , 3 , 4 , 5 , 6 费米子在基本表示。主要结果是该比率没有显示出统计学上显着的N f依赖性。在目前的工作中,我们通过将模拟扩展到N f = 7 , 8 , 9 , 10来继续研究N f依赖性。在此过程中,我们还详细研究了N f依赖于有限体积效应对低能量可观测物和特定平移对称性的破坏,这种对称性打破了交错费米子特有的非物理晶格伪像相位。
