Nonlinear N = 2 $$ \mathcal{N}=2 $$ global supersymmetry
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.

Pure gravity mediation of supersymmetry breaking at the Large Hadron Collider [PDF]
Supersymmetric theories which can allow for a 125 GeV Higgs mass and also solve the naturalness and susy flavor problems now require a fair degree of complexity.

Abstract The string theory landscape may include a multitude of ultraviolet embeddings of the Standard Model, but identifying these has proven difficult due to the enormous number of available string compactifications. Genetic Algorithms (GAs) represent a powerful class of discrete optimisation techniques that can efficiently deal with the immensity of

Supersymmetry Breakings and Fermat's Last Theorem
A mechanism of supersymmetry breaking in two or four-dimensions is given, in which the breaking is related to the Fermat's last theorem. It is shown that supersymmetry is exact at some irrational number points in parameter space, while it is broken at ...

SUSY CP Problem in Gauge Mediation Model [PDF]
SUSY CP problem in the gauge mediation supersymmetry breaking model is reconsidered. We pay particular attention to two sources of CP violating phases whose effects were not seriously studied before; one is the effect of the breaking of the GUT relation ...

Scale hierarchies in particle physics and cosmology
I describe the phenomenology of a model of supersymmetry breaking in the presence of a tiny (tuneable) positive cosmological constant. It utilises a single chiral multiplet with a gauged shift symmetry, that can be identified with the string dilaton (or ...

Gluino decay as a probe of high scale supersymmetry breaking [PDF]
A bstractA supersymmetric standard model with heavier scalar supersymmetric particles has many attractive features. If the scalar mass scale is $ \mathcal{O} $(10−104) TeV, the standard model like Higgs boson with mass around 125 GeV, which is strongly ...

A Study of the Early Cosmic Dynamics in a Multifield Model of Inflation and Curvature Perturbations
In this work, we study the cosmological dynamics of the early universe by employing a small field potential in the context of multifield inflation. By investigating analytically the cosmological observables, such as the number of e‐folds N, potential slow‐roll parameters ϵV, ηV, and spectral index ns which carry significant information, we show that ...

Supersymmetry and its dynamical breaking [PDF]
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 physics.

A minimal SU(5) SuperGUT in pure gravity mediation
The lack of evidence for low-scale supersymmetry suggests that the scale of supersymmetry breaking may be higher than originally anticipated. However, there remain many motivations for supersymmetry including gauge coupling unification and a stable dark ...
