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 ...

Localized supersoft supersymmetry breaking [PDF]
Nuclear Physics B, 2005 We consider supersymmetry breaking models in which the MSSM is extended to include an additional chiral adjoint field for each gauge group with which the the MSSM gauginos acquire Dirac masses. We investigate a framework in which the Standard Model gauge fields propagate in the bulk of a warped extra dimension while quarks and leptons are localized on ...

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

New RG-invariants of Soft Supersymmetry Breaking Parameters [PDF]
, 2000 We study new renormalization-group invariant quantities of soft supersymmetry breaking parameters other than the ratio of gaugino mass to gauge coupling squared by using the spurion method.

Lectures on Supersymmetry Breaking [PDF]
Classical and Quantum Gravity, 2007 We review the subject of spontaneous supersymmetry breaking. First we consider supersymmetry breaking in a semiclassical theory. We illustrate it with several examples, demonstrating different phenomena, including metastable supersymmetry breaking. Then we give a brief review of the dynamics of supersymmetric gauge theories.

Criticality or Supersymmetry Breaking? [PDF]
Symmetry, 2020 In many stochastic dynamical systems, ordinary chaotic behavior is preceded by a full-dimensional phase that exhibits 1/f-type power spectra and/or scale-free statistics of (anti)instantons such as neuroavalanches, earthquakes, etc. In contrast with the phenomenological concept of self-organized criticality, the recently found approximation-free ...

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.
