Moduli stabilisation and the statistics of SUSY breaking in the landscape

open access: yesJournal of High Energy Physics, 2020
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 ...

The Nelson-Seiberg Theorem Generalized with Nonpolynomial Superpotentials

open access: yesAdvances in High Energy Physics, 2020
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.

Supersymmetry, naturalness, and dynamical supersymmetry breaking [PDF]

open access: yesPhysical Review D, 1992
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.

On the stability of open-string orbifold models with broken supersymmetry

open access: yesNuclear 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]

open access: yes, 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 ...

A note on supersymmetry breaking [PDF]

open access: yesPhysics 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

Light higgsino for gauge coupling unification

open access: yesPhysics 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.

Complex Langevin dynamics and supersymmetric quantum mechanics

open access: yesJournal of High Energy Physics, 2021
Using complex Langevin method we probe the possibility of dynamical supersymmetry breaking in supersymmetric quantum mechanics models with complex actions.

Supersymmetry breaking and Nambu-Goldstone fermions with cubic dispersion [PDF]

open access: yes, 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\
