Lectures on Supersymmetry Breaking [PDF]
Class.Quant.Grav.24:S741-S772,2007, 2007 We review the subject of spontaneous supersymmetry breaking. First we consider supersymmetry breaking in a semiclassical theory. We illustrate it with several examples, demonstrating different phenomena, including metastable supersymmetry breaking. Then we give a brief review of the dynamics of supersymmetric gauge theories.

Supersymmetry Breaking, R-Symmetry Breaking and Metastable Vacua [PDF]
JHEP 0707:017,2007, 2007 Models of spontaneous supersymmetry breaking generically have an R-symmetry, which is problematic for obtaining gaugino masses and avoiding light R-axions. The situation is improved in models of metastable supersymmetry breaking, which generically have only an approximate R-symmetry.

Partial N $$ \mathcal{N} $$ = 2 supersymmetry breaking and deformed hypermultiplets [PDF]
Journal of High Energy Physics, 2019 We study partial supersymmetry breaking from N $$ \mathcal{N} $$ = 2 to N $$ \mathcal{N} $$ = 1 by adding non-linear terms to the N $$ \mathcal{N} $$ = 2 supersymmetry transformations.

Gauge-Mediated Supersymmetry Breaking within the Dynamical Messenger Sector [PDF]
Nucl.Phys.Proc.Suppl. 62 (1998) 281-288, 1997 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.

Duality in the Presence of Supersymmetry Breaking [PDF]
Nucl.Phys. B531 (1998) 125-150, 1998 We study Seiberg duality for N=1 supersymmetric QCD with soft supersymmetry-breaking terms. We generate the soft terms through gauge mediation by coupling two theories related by Seiberg duality to the same supersymmetry-breaking sector. In this way, we know what a supersymmetry-breaking perturbation in one theory maps into in its ``dual''.

A Solution to the $μ$ Problem in Gauge-mediated Supersymmetry-breaking Models [PDF]
Phys.Lett. B400 (1997) 109-111, 1997 We point out that a sector required to set the cosmological constant to zero in gauge-mediated supersymmetry-breaking models naturally produces a supersymmetry-invariant mass ($\mu$ term) for Higgs doublets of the order of the electroweak scale. Since this new sector preserves the supersymmetry, it does not generate supersymmetry-breaking masses for ...

Soft supersymmetry-breaking terms from supergravity and superstring models [PDF]
, 1997 We review the origin of soft supersymmetry-breaking terms in N=1 supergravity models of particle physics. We first consider general formulae for those terms in general models with a hidden sector breaking supersymmetry at an intermediate energy scale ...

Hadronic Axion Model in Gauge-Mediated Supersymmetry Breaking [PDF]
Phys.Lett. B437 (1998) 51-61, 1998 A simple hadronic axion model is proposed in the framework of gauge-mediated supersymmetry breaking. Dynamics of Peccei-Quinn symmetry breaking is governed by supersymmetry breaking effects and the Peccei-Quinn breaking scale $f_{PQ}$ is inversely proportional to the gravitino mass. The gravitino mass range which corresponds to the axion window $f_{PQ}

MSSM soft terms from supergravity with gauged R-symmetry in de Sitter vacuum [PDF]
Nuclear Physics B, 2016 We work out the phenomenology of a model of supersymmetry breaking in the presence of a tiny (tunable) positive cosmological constant, proposed by the authors in arXiv:1403.1534. It utilizes a single chiral multiplet with a gauged shift symmetry that can
