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
Explicit R-symmetry breaking and metastable vacua
We consider O'Raifeartaigh-like models with explicit R-symmetry breaking and analyze the vacuum landscape. Taking such models as candidates for the hidden sector, we analyze the gauge mediation ofExpand
Metastable supersymmetry breaking and multitrace deformations of SQCD
Metastable vacua in supersymmetric QCD in the presence of single and multitrace deformations of the superpotential are explored, with the aim of obtaining an acceptable phenomenology. The metastableExpand
Naturalness from runaways in direct mediation
Postulating that the NMSSM singlet is a meson of a microscopic confining theory opens up new model-building possibilities. Based on this, we construct calculable models of direct mediation that solveExpand
More on cosmological constraints on spontaneous R-symmetry breaking models
We study the spontaneous R-symmetry breaking model and investigate the cosmological constraints on this model due to the pseudo Nambu-Goldstone boson, R-axion. We consider the R-axion which hasExpand
Global symmetries and D-terms in supersymmetric field theories
We study the role of D-terms in supersymmetry (SUSY) breaking. By carefully analyzing the SUSY multiplets containing various conserved currents in theories with global symmetries, we obtain a numberExpand
Metastable rank-condition supersymmetry breaking in a chiral example
We discuss generalizations of Intriligator-Seiberg-Shih (ISS) vacua to chiral models. We study one example, of an s-confining theory, in detail. In the IR, this example reduces to two ISS-likeExpand
Semi-direct Gauge-Yukawa mediation
We propose semi-direct Gauge-Yukawa mediation of supersymmetry (SUSY) breaking. The messenger fields mediating SUSY breaking to the visible sector do not directly couple with the goldstino field, andExpand
Generalized messenger sector for gauge mediation of supersymmetry breaking and the soft spectrum
We consider a generic renormalizable and gauge invariant messenger sector and derive the sparticle mass spectrum using the formalism introduced for General Gauge Mediation. Our results recover manyExpand
(De)constructing a natural and flavorful supersymmetric Standard Model

On the Thermal History of Calculable Gauge Mediation
Many messenger models with realistic gaugino masses are based on meta-stable vacua. In this work we study the thermal history of some of these models. Analyzing R-symmetric models, we point out thatExpand


On SQCD with massive and massless flavors
We consider supersymmetric QCD in the free magnetic phase with massless and massive flavors. The theory has a supersymmetry breaking pseudo-moduli space of vacua and a runaway behavior far away fromExpand
Dynamical SUSY breaking in meta-stable vacua
Dynamical supersymmetry breaking in a long-lived meta-stable vacuum is a phenomenologically viable possibility. This relatively unexplored avenue leads to many new models of dynamical supersymmetryExpand
Dynamical breaking of U(1)R and supersymmetry in a metastable vacuum
Abstract We consider the metastable N = 1 QCD model of Intriligator, Seiberg and Shih (ISS), deformed by adding a baryon term to the superpotential. This simple deformation causes the spontaneousExpand
Simple model of direct gauge mediation of metastable supersymmetry breaking
We construct a model of direct gauge mediation of metastable supersymmetry breaking by simply deforming the Intriligator, Seiberg, and Shih model in terms of a dual meson superpotential mass term. NoExpand
A simple model of low-scale direct gauge mediation
We construct a calculable model of low-energy direct gauge mediation making use of the metastable supersymmetry breaking vacua recently discovered by Intriligator, Seiberg and Shih. The standardExpand
Patterns of gauge mediation in metastable SUSY breaking
Supersymmetry breaking in a metastable vacuum allows one to build simple and concrete models of gauge mediation. Generation of gaugino masses requires that R-symmetry be broken in this vacuum. InExpand
Direct Mediation and a Visible Metastable Supersymmetry Breaking Sector
We analyze an R-symmetry breaking deformation of the ISS model for a direct mediation of supersymmetry breaking from a metastable vacuum. The model is weakly coupled and calculable. The LSP gravitinoExpand
Low energy dynamical supersymmetry breaking simplified.
A model in which supersymmetry is dynamically broken at comparatively low energies is presented, which exploits an observation of Bagger, Poppitz and Randall to avoid this problem, and yields a viable example of hidden sector dynamical supers asymmetry breaking. Expand
