The gluino-glue particle and relevant scales for the simulations of supersymmetric Yang-Mills theory

TL;DR

This paper investigates the relevant scales affecting supersymmetry breaking in supersymmetric Yang-Mills theory simulations, focusing on finite size effects and lattice artifacts that influence the gluino-glue particle mass gap.

Contribution

It provides a detailed analysis of the scales at which finite size effects and lattice artifacts impact supersymmetric Yang-Mills simulations, essential for accurate mass gap estimations.

Findings

Finite size effects significantly influence supersymmetry breaking.

Lattice artifacts contribute to the mass gap between particles.

Reevaluation of simulation parameters is necessary for precise results.

Abstract

Supersymmetric Yang-Mills theory is in several respects different from QCD and pure Yang-Mills theory. Therefore, a reinvestigation of the scales, at which finite size effects and lattice artifacts become relevant, is necessary. Both, finite size effects and lattice artifacts, induce a breaking of supersymmetry. In view of the unexpected mass gap between bosonic and fermionic particles an estimation of these effects is essential.
