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.

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.

From linear to non-linear SUSY and back again
Journal of High Energy Physics, 2017 We show that couplings of the goldstino field, appearing when global supersymmetry is broken, can always be described in superspace by means of a nilpotent chiral superfield X, satisfying X 2 = 0.

ASPECTS OF STRING PHENOMENOLOGY IN PARTICLE PHYSICS AND COSMOLOGY
Odessa Astronomical Publications, 2016 We discuss possible connections between several scales in particle physics and cosmology, such the the electroweak, inflation, dark energy and Planck scales.

Is gauge mediation in the swampland?
Physics Letters B, 2023 We note that the typical gauge mediation of supersymmetry breaking is in tension with the global limit of the festina lente swampland bound. The alternatives are mediation/breaking schemes that decouple together with gravity, as for example gravity ...

Non-minimal scalar multiplets, supersymmetry breaking and dualities [PDF]
, 2015 A bstractWe study supersymmetry breaking in theories with non-minimal multiplets (such as the complex linear or CNM multiplets), by using superspace higher derivative terms which give rise to new supersymmetry breaking vacuum solutions on top of the ...

Missing energy signature for low scale supersymmetry breaking
EPJ Web of Conferences, 2017 If the supersymmetry is broken at a scale about several TeVs particles from the sector responsible for the supersymmetry breaking - goldstino and sgoldstino - can reveal themselves already at the LHC experiments.

MSSM soft terms from supergravity with gauged R-symmetry in de Sitter vacuum
Nuclear Physics B, 2016 We work out the phenomenology of a model of supersymmetry breaking in the presence of a tiny (tunable) positive cosmological constant, proposed by the authors in arXiv:1403.1534. It utilizes a single chiral multiplet with a gauged shift symmetry that can

Nilpotent chiral superfield in N=2$$ \mathcal{N}=2 $$ supergravity and partial rigid supersymmetry breaking [PDF]
, 2015 A bstractIn the framework of N=2$$ \mathcal{N}=2 $$ conformal supergravity in four dimensions, we introduce a nilpotent chiral superfield suitable for the description of partial supersymmetry breaking in maximally supersymmetric spacetimes.
