More on the flavor dependence of m ϱ /f π

Abstract

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