Lattice study of meson correlators in theϵ-regime of two-flavor QCD
2008
Physical Review D
We calculate mesonic two-point functions in the epsilon-regime of two-flavor QCD on the lattice with exact chiral symmetry. We use gauge configurations of size 16^3 32 at the lattice spacing a ∼ 0.11 fm generated with dynamical overlap fermions. The sea quark mass is fixed at ∼ 3 MeV and the valence quark mass is varied in the range 1-4 MeV, both of which are in the epsilon-regime. We find a good consistency with the expectations from the next-to-leading order calculation in the
