Hadron masses on a 16^3 x 40 lattice at \beta = 5.7

TL;DR

This paper presents hadron mass spectrum results from lattice QCD simulations on a 16^3 x 40 lattice at 7 = 5.7, highlighting differences in gauge fixing and lighter masses compared to previous studies.

Contribution

First detailed study of hadron masses on a 16^3 x 40 lattice at 7 = 5.7 with two flavors of staggered fermions, extending previous 16^3 x 32 results.

Findings

Mass results are slightly lighter than earlier 16^3 x 32 calculations.

Effective mass plateaus vary with source size.

Landau and Coulomb gauge 7 differences are significant.

Abstract

We report on the hadron mass spectrum obtained on a 16^3 x 40 lattice in full QCD at \beta = 5.7 using two flavors of staggered fermions with m a = 0.01. We study the effective mass plateaus for different sized sources. Our mass results are slightly lighter than our earlier 16^3 x 32 calculation. The Landau gauge \Delta is quite different from the Coulomb gauge \Delta.
