Higgs Boson Exempt No-Scale Supersymmetry and its Collider and Cosmology Implications [PDF]

open access: yes, 2006
One of the most straightforward ways to address the flavor problem of low-energy supersymmetry is to arrange for the scalar soft terms to vanish simultaneously at a scale $M_{c}$ much larger than the electroweak scale.

Minimal Supergravity with m_0^2 < 0

open access: yes, 2005
We extend the parameter space of minimal supergravity to negative values of m_0^2, the universal scalar mass parameter defined at the grand unified scale.

Vacuum decay along supersymmetric flat directions [PDF]

open access: yes, 1995
It has been recently realized that within the Minimal Supersymmetric Standard Model, for certain patterns of superpartner masses, consistent with all the present experimental constraints, the scalar potential may develop at some scale $Q_0$ unbounded ...

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

open access: yesEuropean 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

open access: yesJournal 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]

open access: yes, 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

open access: yesJournal 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.

Predicting the superpartner spectrum from partially composite supersymmetry [PDF]

open access: yesPhysical Review D, 2019
We use the idea of partial compositeness in a minimal supersymmetric model to relate the fermion and sfermion masses. By assuming that the Higgs and third-generation matter is (mostly) elementary, while the first- and second-generation matter is (mostly) composite, the Yukawa coupling hierarchy can be explained by a linear mixing between elementary ...

Supersymmetric inflation from the fifth dimension

open access: yesJournal 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
