Gauge mediation without gravitino problem by virtue of the QCD anomaly

Abstract

We consider the possibility that the Peccei-Quinn charged dynamical supersymmetry breaking (DSB) of m_{3/2}=O(eV) for the Intriligator-Seiberg-Shih model, an axion, converted from a Nambu-Goldstone boson, could become a dark matter candidate, while the QCD anomaly and a sizable \mu value are naturally generated. We also stress that rather minimal DSB content is sufficient to yield the observed mass of the lightest Higgs boson, other than the acceptable soft mass of sparticles in the observable sector.

Comments: I would like to thank you for endorsing me. In this study, I considered the possibility that the gravitino problem could be resovled in gauge mediated supersymmetry breaking. In my framework, the QCD axion could become a good cold dark matter candidate, instead of the light gravitino
