$\mathcal{N}=1$ Supersymmetric $SU(3)$ Gauge Theory -- Pure Gauge sector with a twist (1811.01785v1)

Abstract: Supersymmetric gauge theories are an essential part of most theories beyond the standard model. In the present work we investigate the pure gauge sector of Super-QCD focusing on the bound states, i.e. mesonic gluinoballs, gluino-glueballs and pure glueballs. To improve chiral properties and to minimize breaking of supersymmetry at finite lattice spacing, we introduce a deformed Super-Yang-Mills lattice action. It contains a twist term, similar to the twisted-mass formulation of lattice QCD. We furthermore explore if the multigrid method (DD$\alpha$AMG solver) applied to the gluinos (adjoint Majorana fermions) achieves similar improvements as in QCD.
