N = 4 supersymmetric Yang–Mills theory

N = 4 supersymmetric Yang–Mills (SYM) theory is a special type of quantum field theory that is a cornerstone of theoretical physics, particularly in the study of supersymmetry, gauge theories, and string theory. Here are some key aspects to understand this theory: 1. **Supersymmetry**: This is a symmetry that relates bosons (force carriers) and fermions (matter particles).
