2+1 flavor QCD with the fixed point action in the $\epsilon$-regime

Peter Hasenfratz, Dieter Hierl, Vidushi Maillart +4

We generated configurations with the approximate fixed-point Dirac operator $D_{\mathrm{FP}}$ on a $12^4$ lattice with $a\approx 0.13$fm where the scale was set by $r_0$. The distr…
