Next-to-Minimal Supersymmetric Standard Model

The Next-to-Minimal Supersymmetric Standard Model (NMSSM) is an extension of the Minimal Supersymmetric Standard Model (MSSM), which itself is an extension of the Standard Model of particle physics that incorporates supersymmetry (SUSY). Supersymmetry is a theoretical framework that posits a symmetry between fermions (matter particles) and bosons (force-carrying particles), implying that every known particle has a superpartner with different spin characteristics.
