First results in QCD with 2+1 light flavors using the fixed-point action

Abstract

This is a progress report on 2+1 flavor simulation with the FP action on a lattice with spatial size L=1.2fm. Since m_{ud} is quite small in our simulation we are in the delta regime for the two light flavors where the low lying excitations are described by a quantum mechanical rotator. From here we extract the low energy constant F. We also measure the AWI mass and present results on numerical issues like low-mode averaging and autocorrelation times.
