A comparison of supersymmetry breaking and mediation mechanisms

  • S. P. de Alwis


We give a unified treatment of different models of supersymmetry breaking and mediation from a four dimensional effective field theory standpoint. In particular a comparison between GMSB and various gravity mediated versions of SUSY breaking shows that, once the former is embedded within a SUGRA framework, there is no particular advantage to that mechanism from the point of view of FCNC suppression. We point out the difficulties of all these scenarios — in particular the cosmological modulus problem. We end with a discussion of possible string theory realizations.
