ABSTRACT I present a model of gauge mediation without a messenger sector. This is the first phenomenologically viable model of this type. The sector of dynamical supersymmetry breaking couples directly to the standard model gauge groups. The apparent gauge unification is preserved despite the direct coupling. The inverted hierarchy mechanism plays a crucial role in dynamics. The model is completely chiral, and hence there is no need to forbid mass terms by hand. Still vector-like messengers emerge as a consequence of dynamical breakdown of gauge symmetries.

    ABSTRACT: Conventional approaches to supersymmetric model building suffer from several naturalness problems: they do not explain the large hierarchy between the weak scale and the Planck mass, and they require fine tuning to avoid large flavor changing neutral currents and particle electric dipole moments. The existence of models with dynamical supersymmetry breaking, which can explain the hierarchy, has been known for some time, but efforts to build such models have suffered from unwanted axions and difficulties with asymptotic freedom. In this paper, we describe an approach to model building with supersymmetry broken at comparatively low energies which solves these problems, and give a realistic example.

    ABSTRACT: We describe a class of supersymmetric SU(3)×SU(2)×U(1) models where all quarks and leptons, as well as their scalar partners, get masses through one-loop radiative corrections.

    ABSTRACT: We consider the idea of combining the supersymmetry breaking and messenger sectors in models of gauge-mediated supersymmetry breaking. We discuss the advantages and problems of such models, and present an existence proof by constructing an explicit example. We explore in some detail the low-energy supersymmetry-breaking dynamics and the generation of supersymmetry-breaking soft masses of the standard model superpartners, and discuss many features which are likely to be shared by more realistic models with dynamical messengers.
