Wess-Zumino model
From Wikipedia, the free encyclopedia
In theoretical physics, the Wess-Zumino model has become the first known example of an interacting four-dimensional quantum field theory with supersymmetry, at least in the Western world. In 1974, Julius Wess and Bruno Zumino studied, using modern terminology, dynamics of a single chiral superfield (composed of a complex scalar and a spinor fermion) whose cubic superpotential leads to a renormalizable theory.
