The ISAJET Program
           ISAJET is a program used by Particle Physicists to predict the types of observations you might get, given a specific collider and other input parameters. Here, you will be able to run the program ISASUGRA from the ISAJET package. ISASUGRA is a tool used to calculate the supersymmetric decay modes and soft breaking as well as physical masses. When you are done, you will have the option to run PYTHIA with the particle spectrum generated by ISASUGRA.
           Supersymmetry (SUSY) is a symmetry between particles and their super-symmetric partners. If SUSY were exact the super-particles would have the same mass as their partners and would therefore have been discovered already. Since these particles have not been discovered, either SUSY is not a symmetry of the physical universe, or it is broken in some way. The models below represent different manifestations of SUSY breaking. Click on a model below to begin :
