# New results from mixed-action lattice gauge theory

## TL;DR

This paper investigates potential issues with universality in mixed-action lattice gauge theory for SU(2), highlighting how artifacts can distort results and complicate the separation of physical effects from artifacts.

## Contribution

It clarifies how artifacts influence mixed-action lattice gauge theory results and proposes directions for resolving these issues.

## Key findings

- Artifacts distort the mixed-coupling plane.
- Separating artifacts from physical quantities is intrinsically difficult.
- Further detailed results will be published separately.

## Abstract

We extend and attempt to clarify recent results which showed possible problems for universality for the gauge group SU(2). We suggest that the presence of artifacts actually distorts the mixed-coupling plane. This implies that a separation of artifacts from physical quantities is intrinsically difficult. We suggest what the nature of the resolution might be. Full results will appear elsewhere.
