Description
Suppressed SUSY is a new way of generating a reasonable model for SU(5) GUT theory coupled to Supergravity. The minimal version predicts an extremely heavy stable gravitino as a candidate for dark matter. The rest of the model appears to be consistent with the standard SU(5) model without SUSY. However, Suppressed SUSY improves things: the $X,Y$ vector boson masses are increased to Planck mass, and the questions about scalar bosons are resolved, as is the issue of the cosmological constant (at tree level). But there is a very serious problem: the predicted heavy gravitino is so heavy that it may be impossible to observe it.
