Abstract

Supersymmetry is one of the most promising ideas for physics beyond the standard model. If it is indeed a symmetry of nature, it is realized nonlinearly. In this project, a global nonlinear realization of susy (VolkovAkulov) is examined. First, a general understanding of symmetries in theoretical physics is developed, after which susy is treated on a basic level. The spontaneous breaking of symmetries is discussed, focusing on susy breaking. VA theory is introduced, and the equation of motion is given and analyzed. No negative-energy degrees of freedom or ‘ghosts’ appear to be present. Finally, another Lagrangian is treated (Komargodski-Seiberg), equivalent to that of Volkov and Akulov, emphasizing the universality of VA theory.
