# Light Quenched Hadron Spectrum and Decay Constants on different Lattices

## TL;DR

This study uses quenched lattice QCD simulations with Wilson and SW-Clover actions to compute light hadron spectra and decay constants, achieving close agreement with experimental data for most quantities.

## Contribution

It provides detailed quenched lattice results for hadron masses and decay constants across multiple lattice spacings, with analysis of systematic deviations.

## Key findings

- Mesonic masses agree within 5% of experimental values.
- Baryonic masses and pseudoscalar decay constants agree within 10-15%.
- Vector decay constants show larger deviations.

## Abstract

We present a study of ${\cal O}(2000)$ (quenched) lattice configurations from the APE collaboration, for $6.0\le\beta\le 6.4$ 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.
