Another determination of the quark condensate from an overlap action

Abstract

I use the technique of Hernández et al. to convert a recent calculation of the lattice-regulated quark condensate from an overlap action to a continuum-regulated number. I find ${\Sigma }_{\overline{\mathrm{MS}}}(\mu =2\mathrm{}\hspace{0.5em}\mathrm{GeV})=\left[282\right(6)\mathrm{}\hspace{0.5em}\mathrm{MeV}{]}^3\times {(a}^{-1}/1766\mathrm{}\hspace{0.5em}\mathrm{MeV}{)}^3$ from a calculation with the Wilson gauge action at $\beta =\mathrm{5.9.}\mathrm{}$
