By extending a previously proposed conformal gauge mediation model, we construct a gaugemediated SUSY breaking (GMSB) model where a SUSY-breaking scale, a messenger mass, the μparameter and the gravitino mass in a minimal supersymmetric (SUSY) Standard Model (MSSM) are all explained by a single mass scale, a R-symmetry breaking scale. We focus on a low scale SUSY-breaking scenario with the gravitino mass m3/2 = O(1)eV, which is free from the cosmological gravitino problem and relaxes the fine… 


Semidirect gauge mediation in conformal windows of vectorlike gauge theories
Direct gauge mediation models using the Intriligator-Seiberg-Shih metastable vacua suffer from the Landau pole problem of the standard-model gauge couplings and the existence of R-symmetry forbidding
The upper bound of the second Higgs boson mass in minimal gauge mediation with the gravitino warm dark matter
A keV-scale gravitino arsing from a minimal supersymmetric (SUSY) Standard Model (MSSM) is an interesting possibility since the small scale problems that $\Lambda$CDM model encounters in the modern
Higgs boson mass in low scale gauge mediation models
A bstractWe consider low scale gauge mediation models with a very light gravitino m3/2 ≲ 16 eV, in the light of recent experimental hints on the Higgs boson mass. The light gravitino is very
Viability of MSSM scenarios at very large tan β
We investigate the MSSM with very large tan β > 50, where the fermion masses are strongly affected by loop-induced couplings to the “wrong” Higgs, imposing perturbative Yukawa couplings and
Naive Dimensional Analysis and Supersymmetry
In strongly-coupled theories with no small parameters, there are factors of 4 that appear when the couplings of the low-energy eective lagrangian are written in units of the eective cuto . These
New tools for low energy dynamical supersymmetry breaking.
The construction of large new classes of models which break supersymmetry dynamically are reported, among the new models are examples in which symmetries prevent the appearance of Fayet-Iliopoulos terms.
