Description

Practical lattice discretizations of supersymmetric gauge theories are notoriously difficult to construct in four dimensions. N=4 supersymmetric Yang--Mills (SYM) is the only known 4d theory for which there exists a lattice formulation that exactly preserves a subset of the supersymmetry algebra. This exact supersymmetry has remarkable consequences that are crucial to the feasibility of non-perturbative lattice calculations from first principles. After reviewing some highlights of the N=4 SYM lattice formulation, I will present a selection of results from our ongoing numerical studies, including comparisons with analytic predictions.
