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
There are 2 implemented Non-Minimal Models...
a)Rsl is an extra factor multiplying the gaugino masses at the
messenger scale(Rsl is normally less then 1)
b)dM_Hd^2 and dM_Hu^2 are Higgs mass shifts relative to the messenger
scale minimal model.
c)d_y is a U(1) messenger scale mass term, also known as a D-term
which is proprtional to the hypercharge Y.
d)N5_1,N5_2, and N5_3 are the independent numbers of gauge group
members. They may however be non-integer in general..
