Supersymmetry extends spacetime symmetry by odd supercharges that interchange boson and fermion states. Their Super-Poincaré algebra pairs positive-energy states into supermultiplets and gives energy positivity in global supersymmetry. Superspace and superfields package the component fields into representations of this symmetry.
Supersymmetry (often abbreviated as SUSY) is a theoretical framework in particle physics that posits a relationship between two fundamental classes of particles: bosons and fermions. In the standard model of particle physics, bosons are force-carrying particles (e.g., photons, W and Z bosons, and gluons) that have integer spin, while fermions are matter particles (e.g., quarks and leptons) that have half-integer spin.
