Quenched staggered light hadron spectroscopy from \(48^3\times64\) at \(\beta = 6.5\)

We report our light hadron mass calculation based on an increased statistics of 250 quenched gauge configurations on a (48^3 \times 64) lattice at (\beta = 6.5). Quark propagators are calculated for each of these configurations with staggered wall source and point sink at quark mass values of (m_q =...

description We report our light hadron mass calculation based on an increased statistics of 250 quenched gauge configurations on a (48^3 \times 64) lattice at (\beta = 6.5). Quark propagators are calculated for each of these configurations with staggered wall source and point sink at quark mass values of (m_q = 0.01, 0.005, 0.0025) and (0.00125). We also did additional calculations to improve our understanding of systematic biases arising from autocorrelation, source size, and propagator calculations. Our earlier conclusions that the flavor symmetry breaking is reduced and the ratio (m_N/m_\rho (\sim 1.25(4))) is small remains robust.
