4D N = 1 global supersymmetry

In supersymmetry, 4D ${\displaystyle {\mathcal {N}}=1}$ global supersymmetry is the theory of global supersymmetry in four dimensions with a single supercharge. It consists of an arbitrary number of chiral and vector supermultiplets whose possible interactions are strongly constrained by supersymmetry, with the theory primarily fixed by three functions: the Kähler potential, the superpotential, and the gauge kinetic matrix. Many common models of supersymmetry are special cases of this general theory, such as the Wess–Zumino model, ${\displaystyle {\mathcal {N}}=1}$ super Yang–Mills theory, and the Minimal Supersymmetric Standard Model. When gravity is included, the result is described by 4D ${\displaystyle {\mathcal {N}}=1}$ supergravity.
