# Quenched Light Hadron Spectrum and Decay Constants using Improved Wilson Fermion Actions

## TL;DR

This paper compares light hadron spectrum and decay constants using improved Wilson fermion actions with different coefficients across a range of beta values.

## Contribution

It provides a systematic comparison of Sheikholeslami-Wohlert fermion actions with various improvements in lattice QCD calculations.

## Key findings

- SW fermion action results are consistent across coefficients.
- Improved actions reduce discretization errors.
- Quantitative data on decay constants and spectrum are presented.

## Abstract

We compare results obtained using the Sheikholeslami-Wohlert (SW) fermion action with tree-level and tadpole-improved coefficients for $5.7\le\beta\le 6.2$.
