Finite Size Effects on the QCD Spectrum Revisited
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 amq=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 mπ/m than previously studied with two dynamical flavors.
