Abstract

We have continued our study of finite size effects in the QCD spectrum on lattices ranging in size from 8³ × 24 to 16³ × 24. We have increased our statistics for quark mass am_q = 0.025 for the smallest lattice size. In addition, we have studied quark mass 0.0125 for lattice sizes 12³ × 24 and 16³ × 24. These lattice sizes correspond to a box 1.8-3.6 fm on a side when the rho mass at zero quark mass is used to set the scale. We discuss the nucleon to rho mass ratio at a smaller value of m_π/m_ρ{variant} than previously studied with two dynamical flavors.
