Universality, Scaling and Topology with a Modified Lattice Action

TL;DR

This paper investigates how removing negative plaquettes in a lattice gauge theory affects various physical quantities, providing insights into universality and scaling behaviors.

Contribution

It introduces a modified lattice action that suppresses negative plaquettes and studies its impact on key physical observables.

Findings

Suppression of negative plaquettes alters critical temperature and string tension.

Topological charge and glueball mass ratios are affected by the modified action.

Results suggest modifications influence universality and scaling properties.

Abstract

We examined the effect of a complete suppression of a lattice artifact, the negative plaquettes, on physical quantities, such as the critical temperature, the string tension, the topological charge, glueball masses, and their ratios.
