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 ...

Breaking supersymmetry with pure spinors

Journal of High Energy Physics, 2020
For several classes of BPS vacua, we find a procedure to modify the PDEs that imply preserved supersymmetry and the equations of motion so that they still imply the latter but not the former.

Duality in the Presence of Supersymmetry Breaking [PDF]

, 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.

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 ...

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.

Moduli backreaction and supersymmetry breaking in string-inspired inflation models [PDF]

, 2015
A bstractWe emphasize the importance of effects from heavy fields on supergravity models of inflation. We study, in particular, the backreaction of stabilizer fields and geometric moduli in the presence of supersymmetry breaking.

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 ...

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
