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

Gauge/Anomaly Syzygy and Generalized Brane World Models of Supersymmetry Breaking [PDF]
, 2001 In theories in which SUSY is broken on a brane separated from the MSSM matter fields, supersymmetry breaking is naturally mediated in a variety of ways.

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.

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.

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 ...

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.

Effective Messenger Sector from Dynamical Supersymmetry Breaking [PDF]
Nucl.Phys. B497 (1997) 31-40, 1996 In the framework of the dynamical supersymmetry breaking we construct the messenger sector as the effective theory of supersymmetry breaking sector, which is based on SU(3) \times SU(2) model of Affleck, Dine and Seiberg. In our model, messenger superfields with non-renormalizable interaction are contained.

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.

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.

Possible Approach to Dynamical Supersymmetry Breaking via Nambu-Jona-Lasinio Model
EPJ Web of Conferences, 2018 Supersymmetry is undoubtedly a popular candidate for physics beyond the Standard Model. However, the origin of soft supersymmetry breaking masses has been usually depicted intricately in the literature via extra hidden/mediating sectors.
