The low-lying spectrum of N=1 supersymmetric Yang-Mills theory

TL;DR

This paper presents a lattice calculation of the lightest bound state spectrum in N=1 supersymmetric Yang-Mills theory with SU(2), showing evidence for degenerate supermultiplets after extrapolations.

Contribution

It provides the first lattice-based spectrum analysis of N=1 supersymmetric Yang-Mills theory with detailed extrapolations to the continuum and massless limits.

Findings

Mass spectrum consistent with supermultiplet formation

Degeneracy observed among superpartners

Results support supersymmetry realization in lattice simulations

Abstract

The spectrum of the lightest bound states in N=1 supersymmetric Yang-Mills theory with SU(2) gauge group, calculated on the lattice, is presented. The masses have first been extrapolated towards vanishing gluino mass and then to the continuum limit. The final picture is consistent with the formation of degenerate supermultiplets.
