# New fixed point action for SU(3) lattice gauge theory

## TL;DR

This paper introduces a new fixed point action for SU(3) lattice gauge theory that improves upon previous actions by reducing interaction range and rotational symmetry violations, enhancing simulation accuracy.

## Contribution

The paper proposes a novel fixed point action for SU(3) lattice gauge theory with shorter interaction range and fewer symmetry violations compared to prior actions.

## Key findings

- Shorter interaction range achieved.
- Reduced violations of rotational symmetry.
- Improved accuracy in static quark-antiquark potential measurements.

## Abstract

We present a new fixed point action for SU(3) lattice gauge theory, which has --- compared to earlier published fixed point actions --- shorter interaction range and smaller violations of rotational symmetry in the static $q\bar{q}$-potential even at shortest distances.
