“…In particular, for low-dimensional gauge theories with extended supersymmetries, lattice models could avoid fine-tuning for the continuum limit due to partially preserved supercharges. In [5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21], the lattice supersymmetric gauge models preserving one or two supercharges are proposed based on the discretized topologically twisted gauge theories (for relations among several lattice formulations, see [22,23,24,25,26]). Since the supersymmetries are partially preserved in the models, the numerical simulation can be carried out on the basis similar to lattice QCD [27,28,29,30,31,32,33,34].…”
