We study gauge mediation of supersymmetry breaking in SU(5) supersymmetric grand unified theory with gauge fields as messengers. The generated soft supersymmetry breaking parameters lead to close to maximal mixing scenario for the Higgs mass and highly reduce the fine tuning of electroweak symmetry breaking. All gaugino, squark and slepton masses are determined by one parameter – the supersymmetry breaking scale. The characteristic features are: negative and non-universal squark and slepton… Expand

Moduli stabilization and supersymmetry breaking in deflected mirage mediation
We present a model of supersymmetry breaking in which the contributions from gravity/modulus, anomaly, and gauge mediation are all comparable. We term this scenario ``deflected mirage mediation'',Expand
Realization of a spontaneous gauge and supersymmetry breaking vacuum

Natural gauge mediation with a Bino next-to-lightest supersymmetric particle at the LHC.
TLDR
The ATLAS diphoton search with 4.8 b(-1) of data is used to place limits in both the top-squark-gluino and neutralino-chargino mass planes, providing the first nontrivial constraints in natural gauge mediation models with a neutralino next-to-lightest supersymmetric particle decaying to photons.
