Dynamical supersymmetry breaking [PDF]
I review the motivation for dynamical supersymmetry breaking, the various mechanisms which have been discovered, and the prospects for model building.

Higgs in nilpotent supergravity: Vacuum energy and Festina Lente
In this note we study supergravity models with constrained superfields. We construct a supergravity framework in which all (super)symmetry breaking dynamics happen in vacuum with naturally (or otherwise asymptotically) vanishing energy.

Dilaton supersymmetry breaking [PDF]
We argue that dilaton supersymmetry breaking in string derived supergravity requires an effective superpotential which is not separable as a function of the dilaton times a function of the moduli. We show that in a simple model with hidden sector matter condensation and a dilaton independent term one can easily obtain $|F_S| \not=0$.

Moduli stabilisation and the statistics of SUSY breaking in the landscape
The statistics of the supersymmetry breaking scale in the string landscape has been extensively studied in the past finding either a power-law behaviour induced by uniform distributions of F-terms or a logarithmic distribution motivated by dynamical ...

Supersymmetry, naturalness, and dynamical supersymmetry breaking [PDF]
Models with dynamical supersymmetry breaking have the potential to solve many of the naturalness problems of hidden sector supergravity models. We review the argument that in a generic supergravity theory in which supersymmetry is {\it dynamically} broken in the hidden sector, only tiny Majorana masses for gauginos are generated.

The Nelson-Seiberg Theorem Generalized with Nonpolynomial Superpotentials
The Nelson-Seiberg theorem relates R-symmetries to F-term supersymmetry breaking and provides a guiding rule for new physics model building beyond the Standard Model.

Light higgsino for gauge coupling unification
We explore gauge coupling unification and dark matter in high scale supersymmetry where the scale of supersymmetry breaking is much above the weak scale.

On the stability of open-string orbifold models with broken supersymmetry
We consider an open-string realisation of N=2→N=0 spontaneous breaking of supersymmetry in four-dimensional Minkowski spacetime. It is based on type IIB orientifold theory compactified on T2×T4/Z2, with Scherk–Schwarz supersymmetry breaking implemented ...

Using complex Langevin method we probe the possibility of dynamical supersymmetry breaking in supersymmetric quantum mechanics models with complex actions.
