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

@article{Giveon2008DynamicalSA, title={Dynamical SUSY and R-symmetry breaking in SQCD with massive and massless flavors}, author={Amit Giveon and Andrey Katz and Z. Komargodski and David Shih}, journal={Journal of High Energy Physics}, year={2008}, volume={2008}, pages={092-092} }

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… Expand
