Supergravity with a Gravitino LSP [PDF]

, 2004
We investigate supergravity models in which the lightest supersymmetric particle (LSP) is a stable gravitino. We assume that the next-lightest supersymmetric particle (NLSP) freezes out with its thermal relic density before decaying to the gravitino at ...

On FLRW reductions of $$N=1$$ N = 1 supergravity

European Physical Journal C: Particles and Fields
An FLRW reduction of $$N=1$$ N = 1 supergravity is troublesome since spatial isotropy prohibits a non-vanishing Rarita–Schwinger field. In view of this, we consider the quadratic form $$\psi _m^{\ \alpha } \psi _{n\alpha }$$ ψ m α ψ n α arising from a ...

Saxion cosmology for thermalized gravitino dark matter

Journal of High Energy Physics, 2017
In all supersymmetric theories, gravitinos, with mass suppressed by the Planck scale, are an obvious candidate for dark matter; but if gravitinos ever reached thermal equilibrium, such dark matter is apparently either too abundant or too hot, and is ...

Minimal Gaugino Mediation [PDF]

, 2000
We propose Minimal Gaugino Mediation as the simplest known solution to the supersymmetric flavor and CP problems. The framework predicts a very minimal structure for the soft parameters at ultra-high energies: gaugino masses are unified and non-vanishing

Charting generalized supersoft supersymmetry

Journal of High Energy Physics, 2018
Without any shred of evidence for new physics from LHC, the last hiding spots of natural electroweak supersymmetry seem to lie either in compressed spectra or in spectra where scalars are suppressed with respect to the gauginos.

ATLAS diboson excess from low scale supersymmetry breaking [PDF]

, 2015
We provide an interpretation of the recent ATLAS diboson excess in terms of a class of supersymmetric models in which the scale of supersymmetry (SUSY) breaking is in the few TeV range.

Supersymmetric inflation from the fifth dimension

Journal of High Energy Physics, 2019
We develop a supersymmetric bi-axion model of high-scale inflation coupled to supergravity, in which the axionic structure originates from, and is protected by, gauge symmetry in an extra dimension. While local supersymmetry (SUSY) is necessarily Higgsed

Supersymmetric Relations Among Electromagnetic Dipole Operators

, 2001
Supersymmetric contributions to all leptonic electromagnetic dipole operators have essentially identical diagramatic structure. With approximate slepton universality this allows the muon anomalous magnetic moment to be related to the electron electric ...
