Light Bound States in N=1 SU(2) SUSY Yang-Mills Theory — Sajid Ali¹, Georg Bergner², •Henning Gerber¹, Pietro Giudice¹, Simon Kuberski¹, Istvan Montvay³, Gernot Münster¹, Philipp Scior¹, and Stefano Piemonte⁴ — ¹Universität Münster — ²Universität Jena — ³DESY Hamburg — ⁴Universität Regensburg

Supersymmetry has been investigated for more than forty years. However, the non-perturbative nature of supersymmetric field theories is still largely unknown.

We study non-perturbative properties of N=1 supersymmetric Yang-Mills theory (SYM) within the lattice field theory approach using Monte Carlo simulations. Similar to QCD, SYM is confining and contains strongly bound states.

Applying the variational method together with different smearing techniques we extract masses of the lightest bound states such as gluino-glue, glueball and mesonic states. As these states should form supermultiplets, this study allows to check whether SYM remains supersymmetric also on the quantum level.
