Finite-volume corrections to low-energy constants from the partially quenched effective theory

Abstract

We calculate finite-volume corrections to the low-energy constants $\Sigma$ and $F$ in the epsilon-regime of QCD using partially quenched chiral perturbation theory in the supersymmetry formulation without a singlet particle. We comment on how to minimize these corrections in lattice simulations of QCD.
