N=1 supersymmetric SU(3) Yang-Mills theory on the lattice — •Marc Steinhauser, Andreas Wipf, André Sternbeck, and Björn Wellegehausen — Theoretisch-Physikalisches Institut, Friedrich-Schiller-Universität Jena, 07743 Jena, Germany

We investigate the fourdimensional SU(3) Yang-Mills theory with N=1 supersymmetry. This theory contains meson-like gluinoballs, gluino-glueballs and pure glueballs as bound states. In my talk, I will present first results with focus on particle masses. Another part of our investigation aims at the understanding of the chiral symmetry and its breaking mechanism. A fine tuning of the bare gluino mass is necessary to ensure the restauration of the supersymmetry and the chiral symmetry in the continuum limit. After setting the scale, we can relate the dimensionless lattice quantities to physical observables and compare them to their counter-parts in quantum chromodynamics.
