Scale hierarchies in particle physics and cosmology
EPJ Web of Conferences, 2018 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 ...

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.

Supersymmetry Breaking Vacua from M Theory Fivebranes
, 2007 We consider intersecting brane configurations realizing N=2 supersymmetric gauge theories broken to N=1 by multitrace superpotentials, and softly to N=0.

Gaugino-Assisted Anomaly Mediation [PDF]
, 2000 We present a model of supersymmetry breaking mediated through a small extra dimension. Standard model matter multiplets and a supersymmetry-breaking (or ``hidden'') sector are confined to opposite four-dimensional boundaries while gauge multiplets live ...

Gluino decay as a probe of high scale supersymmetry breaking [PDF]
, 2012 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 ...

Exploring T‐Duality for Self‐Dual Fields
Fortschritte der Physik, Volume 72, Issue 5, May 2024.Abstract Avatars of T‐duality within Sen's formalism for self‐dual field strengths in various dimensions are studied. This formalism is shown to naturally accommodate the T‐duality relation between Type IIA/IIB theories when compactified on a circle without the need for imposing the self‐duality constraint by hand, as is usually done. The study of this

A minimal SU(5) SuperGUT in pure gravity mediation
European Physical Journal C: Particles and Fields, 2019 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 ...

Reheating after inflation by supersymmetry breaking
European Physical Journal C: Particles and Fields, 2021 We study reheating after the end of inflation in models where the inflaton is the superpartner of goldstino and is charged under a gauged U(1) R-symmetry. We consider two classes of models – one is small field characterized by an almost flat Kähler space,

Asymptotically‐Flat Black Hole Solutions in Symmergent Gravity
Fortschritte der Physik, Volume 72, Issue 4, April 2024.Abstract Symmergent gravity is an emergent gravity model with an R+R2$R+R^2$ curvature sector and an extended particle sector having new particles beyond the known ones. With constant scalar curvature, asymptotically flat black hole solutions are known to have no sensitivity to the quadratic curvature term (coefficient of R2$R^2$). With variable scalar
