Minimal R+R2 supergravity models of inflation coupled to matter

Physics Letters B, 2014
The supersymmetric extension of “Starobinsky” R+αR2 models of inflation is particularly simple in the “new minimal” formalism of supergravity, where the inflaton has no scalar superpartners.

Resonant slepton production and right sneutrino dark matter in left-right supersymmetry

Journal of High Energy Physics, 2017
Right-handed sneutrinos are natural components of left-right symmetric supersymmetric models where the gauge sector is extended to include right-handed weak interactions.

Supersymmetry and eigensurface topology of the spherical quantum pendulum [PDF]

, 2015
We undertook a mutually complementary analytic and computational study of the full-fledged spherical (3D) quantum rotor subject to combined orienting and aligning interactions characterized, respectively, by dimensionless parameters $\eta$ and $\zeta ...

Sequestered Dark Matter

, 2008
We show that hidden-sector dark matter is a generic feature of the type IIB string theory landscape and that its lifetime may allow for a discovery through the observation of very energetic gamma-rays produced in the decay.

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 ...

Naturalness and the Status of Supersymmetry

, 2013
For decades, the unnaturalness of the weak scale has been the dominant problem motivating new particle physics, and weak-scale supersymmetry has been the dominant proposed solution.

Bounds on Supersymmetry from Electroweak Precision Analysis [PDF]

, 1998
The Standard Model global fit to precision data is excellent. The Minimal Supersymmetric Standard Model can also fit the data well, though not as well as the Standard Model.

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.

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
