MGMSB:Minimal Gauge Mediated SUSY Breaking model of Dine, Nelson, and collaborators
In this model the gauge interactions from the standard model act as the messenger
fields of SUSY breaking. This is accomplished by requiring the fields within the SUSY
breaking sector to transform under the standard model gauge group. The Messenger energy
scale is well below the gravitational scale of the SUGRA models. In GMSB models the
lightest Supersymmetric Particle(LSP) is always the nearly massless Gravitino. One very
attractive feature of this model is that flavor-changing neutral currents are suppressed
without additional assumptions.
