Meson correlation functions in the ϵ-regime

We present a numerical pilot study of the meson correlation functions in the ϵ-regime of chiral perturbation theory (χPT). Based on simulations with overlap fermions we measured the axial and pseudo-scalar correlation functions, and we discuss the implications for the leading low energy constants in...

Description
Summary:We present a numerical pilot study of the meson correlation functions in the ϵ-regime of chiral perturbation theory (χPT). Based on simulations with overlap fermions we measured the axial and pseudo-scalar correlation functions, and we discuss the implications for the leading low energy constants in the chiral Lagrangian.
