Research

Dine works on the "phenomenology" (''i.e.'' experimentally testable models for low energy) of supersymmetric extensions of the Standard Model and of superstring theory. In particular, he does research on
supersymmetry breaking In particle physics, supersymmetry breaking is the process to obtain a seemingly non-supersymmetric physics from a supersymmetric theory which is a necessary step to reconcile supersymmetry with actual experiments. It is an example of spontaneous s ...
