Generalized Supersoft Supersymmetry Breaking and a Solution to the μ Problem. [PDF]

Physical Review Letters, 2015
We propose the framework generalized supersoft supersymmetry breaking. "Supersoft" models, with D-type supersymmetry breaking and heavy Dirac gauginos, are considerably less constrained by the LHC searches than the well studied MSSM.

Resurgence of a de Sitter Glauber‐Sudarshan State: Nodal Diagrams and Borel Resummation

Fortschritte der Physik, Volume 71, Issue 12, December 2023., 2023
Abstract It is shown in this article that an explicit construction of a four‐dimensional de Sitter space may be performed using a diagrammatic approach via nodal diagrams emanating from the path integral representation of the Glauber‐Sudarshan state. Sum of these diagrams typically leads to an asymptotic series of Gevrey kind which can then be Borel ...

A Note on Modular Invariant Species Scale and Potentials

Fortschritte der Physik, Volume 71, Issue 10-11, November 2023., 2023
Abstract The species scale provides an upper bound for the ultraviolet cutoff of effective theories of gravity coupled to a number of light particle species. Modular invariant (super‐)potentials provide a simple and computable expression of the species scale as a function of the moduli in toroidal orbifold compactifications of type II and heterotic ...

COSMOLOGICAL BREAKING OF SUPERSYMMETRY? [PDF]

Strings 2000, 2001
This is the text of my talk at the Strings 2000 Conference at the University of Michigan. It consists of three interlocking conjectures about the nature of SUSY breaking and the Cosmological Constant, as well as evidence from a toy model that demonstrates the validity of the claim that systems with a UV/IR connection can exhibit much larger SUSY ...

The scale of supersymmetry breaking as a free parameter [PDF]

, 2001
While supersymmetric extensions of the Standard Model can be fully described in terms of explicitly broken global supersymmetry, this description is only effective.

Peccei-Quinn Symmetry from Dynamical Supersymmetry Breaking [PDF]

, 2015
The proximity of the Peccei-Quinn scale to the scale of supersymmetry breaking in models of pure gravity mediation hints at a common dynamical origin of these two scales.

Supersymmetric Reshaping and Higher‐Dimensional Rearrangement of Photonic Lattices

Laser &Photonics Reviews, Volume 17, Issue 10, October 2023., 2023
Self‐imaging Jx photonic lattices enable perfect transfer of quantum and classical states, yet are challenging to implement at scale. In this paper, supersymmetry is harnessed to construct 2D systems with spectra identical to that of 1D Jx lattices that retain their key imaging and state transfer properties, while requiring dramatically fewer distinct ...

Sparticle spectrum and constraints in anomaly mediated supersymmetry breaking models [PDF]

, 2002
We study in detail the particle spectrum in anomaly mediated supersymmetry breaking models in which supersymmetry breaking terms are induced by the super-Weyl anomaly.

Nonstandard supersymmetry breaking and Dirac gaugino masses without supersoftness [PDF]

, 2015
I consider models in which non-standard supersymmetry breaking terms, including Dirac gaugino masses, arise from F-term breaking mediated by operators with a $1/M^3$ suppression.

Brane induced supersymmetry breaking and de Sitter supergravity [PDF]

Journal of High Energy Physics, 2015
We obtain a four-dimensional supergravity with spontaneously broken super-symmetry allowing for de Sitter vacua by coupling a superspace action of minimal N = 1, D = 4 supergravity to a locally supersymmetric generalization of the Volkov-Akulov goldstino
