Brane supersymmetry breaking [PDF]
Physics Letters B, 1999 We show how to construct chiral tachyon-free perturbative orientifold models, where supersymmetry is broken at the string scale on a collection of branes while, to lowest order, the bulk and the other branes are supersymmetric. In higher orders, supersymmetry breaking is mediated to the remaining sectors, but is suppressed by the size of the transverse

A note on supersymmetry breaking [PDF]
Physics Letters B, 1997 Using a simple observation based on holomorphy, we argue that any model which spontaneously breaks supersymmetry for some range of a parameter will do so generically for all values of that parameter, modulo some isolated exceptional points. Conversely, a model which preserves supersymmetry for some range of a parameter will also do so everywhere except

On the stability of open-string orbifold models with broken supersymmetry
Nuclear Physics B, 2020 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 ...

Supersymmetry breaking in spatially modulated vacua [PDF]
, 2017 We study spontaneous supersymmetry breaking in spatially modulated stable or meta-stable vacua in supersymmetric field theories. Such spatial modulation can be realized in a higher derivative chiral model for which vacuum energies are either positive ...

Dilaton supersymmetry breaking [PDF]
Physics Letters B, 1996 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 $|F_S| \not=0$.

Light higgsino for gauge coupling unification
Physics Letters B, 2017 We explore gauge coupling unification and dark matter in high scale supersymmetry where the scale of supersymmetry breaking is much above the weak scale.

Supersymmetry breaking and Nambu-Goldstone fermions with cubic dispersion [PDF]
, 2016 We introduce a lattice fermion model in one spatial dimension with supersymmetry (SUSY) but without particle number conservation. The Hamiltonian is defined as the anticommutator of two nilpotent supercharges $Q$ and ${Q}^{\ifmmode\dagger\else\textdagger\

DYNAMICAL SUPERSYMMETRY BREAKING [PDF]
Annual Review of Nuclear and Particle Science, 1998 ▪ Abstract Dynamical supersymmetry breaking is a fascinating theoretical problem that is also of phenomenological significance. A better understanding of this phenomenon can help in model building, which in turn is useful in guiding the search for supersymmetry.
