Flavor in SU(5)$SU(5)$ Finite Grand Unified Models
Fortschritte der Physik, Volume 72, Issue 12, December 2024.Abstract Four SU(5)N=1$SU(5) \nobreakspace N=1$ supersymmetric models which exhibit S3$S_3$ and/or ZN$Z_N$ symmetries are studied, that are finite to two or all loops, and their corresponding mass matrices. The first is an all‐loop finite model based on an S3×Z3×Z2$S_3\times Z_3\times Z_2$ flavor symmetry, which leads to phenomenologically nonviable ...

Supersymmetry and Its Dynamical Breaking [PDF]
, 2020 This article reviews the subject of supersymmetry and its breaking. The emphasis is on recent developments in metastable, dynamical supersymmetry breaking, which permit the construction of promising models of particle ...

Testing cosmological supersymmetry breaking [PDF]
, 2001 Banks has proposed a relation between the scale of supersymmetry breaking and the cosmological constant in de Sitter space. His proposal has a natural extension to a general FRW cosmology, in which the supersymmetry breaking scale is related to the ...

Nearly Supersymmetric Dark Atoms
Advances in High Energy Physics, 2011 Theories of dark matter that support bound states are an intriguing possibility for the identity of the missing mass of the Universe. This article proposes a class of models of supersymmetric composite dark matter where the interactions with the Standard

Nonlinear N = 2 $$ \mathcal{N}=2 $$ global supersymmetry
Journal of High Energy Physics, 2017 We study the partial breaking of N = 2 $$ \mathcal{N}=2 $$ global supersymmetry, using a novel formalism that allows for the off-shell nonlinear realization of the broken supersymmetry, extending previous results scattered in the literature.

Asymptotic Behavior of Saxion–Axion System in Stringy Quintessence Model
Fortschritte der Physik, Volume 72, Issue 11, November 2024.Abstract The late time behavior of the slow‐roll parameter in the stringy quintessence model is studied when axion as well as saxion are allowed to move. Even though the potential is independent of the axion at tree level, the axion can move through its coupling to the saxion and the background geometry.

Brane-induced supersymmetry breaking [PDF]
, 2002 We study spontaneous supersymmetry breaking induced by brane-localized dynamics in five-dimensional supergravity compactified on S1/Z2. We consider a model with gravity in the bulk and matter localized on tensionless branes at the orbifold fixed points ...

N=2 supersymmetry partial breaking and tadpole anomaly
Nuclear Physics B, 2015 We consider the U(1)n extension of the effective N=2 supersymmetric U(1)×U(1) model of arXiv:1204.2141; and study the explicit relationship between partial breaking of N=2 supersymmetry constraint and D3 brane tadpole anomaly of type IIB string on Calabi–

Soft supersymmetry breaking on the brane [PDF]
Physical Review D, 2004 We consider the low energy description of five dimensional models of supergravity with boundaries comprising a vector multiplet and the universal hypermultiplet in the bulk. We analyse the spontaneous breaking of supersymmetry induced by the vacuum expectation value of superpotentials on the boundary branes.
