# First results with non-perturbative fermion improvement

## TL;DR

This paper reports initial findings on light hadron masses and nucleon structure functions using a non-perturbative fermion improvement method that reduces lattice artifacts, showing improved linearity and more accurate axial coupling values.

## Contribution

It introduces a non-perturbative fermion improvement technique that effectively eliminates $O(a)$ effects in Wilson fermion simulations within the quenched approximation.

## Key findings

- More linear APE plots observed
- Axial coupling $g_A$ closer to experimental value
- Initial results suggest improved simulation accuracy

## Abstract

We present initial results for light hadron masses and nucleon structure functions using a recent proposal for eliminating all $O(a)$ effects from Wilson fermion simulations in the quenched approximation. With initially limited statistics, we find a much more linear APE plot and a value of the axial coupling $g_A$ nearer to the experimental point than with comparable runs using unimproved Wilson fermions.
