Simulating chiral quarks in the ε-regime of QCD

We present simulation results for lattice QCD with chiral fermions in small volumes, where the ε-expansion of chiral perturbation theory ( χ PT) applies. Our data for the low lying Dirac eigenvalues, as well as mesonic correlation functions, are in agreement with analytical predictions. This allows...

Description
Summary:We present simulation results for lattice QCD with chiral fermions in small volumes, where the ε-expansion of chiral perturbation theory ( χ PT) applies. Our data for the low lying Dirac eigenvalues, as well as mesonic correlation functions, are in agreement with analytical predictions. This allows us to extract values for the leading Low Energy Constants F π and Σ.
