Dynamical SUSY and R-symmetry breaking in SQCD with massive and massless flavors

Understand

We show that supersymmetry and R-symmetry can be dynamically broken in a long-lived metastable vacuum of SQCD with massive and massless flavors.

• The vacuum results from a competition of a (leading) two-loop effect and small "Planck" suppressed higher-dimension operators.
• This mechanism provides a particularly simple realization of dynamical SUSY and R-symmetry breaking, and as such it is a good starting point for building phenomenologically viable models of gauge mediation.
• We take a preliminary step in this direction by constructing a complete model of minimal gauge mediation.
