The Decay of the Inflaton in No-scale Supergravity [PDF]

open access: yes, 2006
We study the decay of the inflaton in no-scale supergravity and show that decay due to the gravitational interactions through supergravity effects is highly suppressed relative to the case in minimal supergravity or models with a generic Kahler potential.

Sneutrino as the lightest supersymmetric particle in B{sub 3} minimal supergravity models and signals at the LHC [PDF]

open access: yes, 2008
We consider B{sub 3} minimal supergravity models where we have one lepton number violating L{sub i}Q{sub j}D{sub k} operator at the grand unification scale.

On the paper “Bundle gerbes” by Michael Murray

open access: yesJournal of the London Mathematical Society, Volume 113, Issue 1, January 2026.
Abstract The article gives a brief survey of Murray's notion of bundle gerbes as introduced in his 1996 paper published in the Journal of the London Mathematical Society, together with some of its applications.

Super throats with non trivial scalars

open access: yesJournal of High Energy Physics, 2020
We find new BPS solutions in N = 2 D = 4 Fayet-Iliopoulos gauged super- gravity with STU prepotential. These are stationary solutions carrying a Kerr-Newman throat spacetime geometry and are everywhere regular.

Non-Lorentzian IIB supergravity from a polynomial realization of SL(2, ℝ)

open access: yesJournal of High Energy Physics, 2023
We derive the action and symmetries of the bosonic sector of non-Lorentzian IIB supergravity by taking the non-relativistic string limit. We find that the bosonic field content is extended by a Lagrange multiplier that implements a restriction on the ...

Higher Curvature Supergravity, Supersymmetry Breaking and Inflation

open access: yes, 2014
In these lectures, after a short introduction to cosmology, we discuss the supergravity embedding of higher curvature models of inflation. The supergravity description of such models is presented for the two different formulations of minimal supergravity.

Operando Acoustic Spectroscopy for Optimizing Gas Evolution In Hydrogen Evolution Reaction and the Oxygen Evolution Reaction Processes

open access: yesChemElectroChem, Volume 12, Issue 19, October 3, 2025.
The graphic enables the visualization of the changes in audible frequency within the cell when the potential is applied at 30 s. The change in frequency is related to the gas volume produced during electrolysis. The gas changes the compressibility of the electrolyte slowing down the speed of sound.

De sitter magnetic black hole dipole with a supersymmetric horizon

open access: yesJournal of High Energy Physics, 2021
We find a new non BPS solution in N = 2 D = 4 gauged supergravity coupled to U(1) gauge fields and matter. It consists in a closed universe with two extremal black holes of equal size, surrounding two singularities.

Susy Particles [PDF]

open access: yes, 1994
Analysis of the SUSY spectrum in supergravity unified models is given under the naturalness criterion that the universal scalar mass $(m_0)$ and the gluino mass $(m_{\tilde g})$ satisfy the constraint $m_0, m_{\tilde g}$ less than or equal to 1 TeV.
