A Simple Model of Low-scale Direct Gauge Mediation
Authors: Csaba Cski, Yuri Shirman, John Terning
Abstract: We construct a calculable
model of low-energy direct gauge mediation making use of the metastable
supersymmetry breaking vacua recently discovered by Intriligator,
Seiberg and Shih. The standard model gauge group is a subgroup of the
global symmetries of the SUSY breaking sector and messengers play an
essential role in dynamical SUSY breaking: they are composites of a
confining gauge theory, and the holomorphic scalar messenger mass
appears as a consequence of the confining dynamics. The SUSY breaking
scale is around 100 TeV nevertheless the model is calculable. The
minimal non-renormalizable coupling of the Higgs to the DSB sector leads
in a simple way to a mu-term, while the B-term arises at two-loop order
resulting in a moderately large tan beta. A novel feature of this class
of models is that some particles from the dynamical SUSY breaking sector
may be accessible at the LHC.
