Light Quenched Hadron Spectrum and Decay Constants on different Lattices

Abstract

We present a study of ${\cal O}(2000)$ (quenched) lattice configurations from the APE collaboration, for $6.0\leβ\le 6.4$ using both the Wilson and the SW-Clover fermion action. We determine the light hadronic spectrum and meson decay constants. We extract the inverse lattice spacing using data at the simulated values of the quark mass. We find an agreement with the experimental data of $\sim 5%$ for mesonic masses and $\sim 10%-15%$ for baryonic masses and pseudoscalar decay constants. A larger deviation is present for the vector decay constants.
