Warped compactification to de Sitter space [PDF]

open access: yes, 2011
We explore in detail the prospects of obtaining a four-dimensional de Sitter universe in classical supergravity models with warped and time-independent extra dimensions, presenting explicit cosmological solutions of the $(4+n)$-dimensional Einstein ...

Phenomenological Aspects of Heterotic Orbifold Models at One Loop

open access: yes, 2003
We provide a detailed study of the phenomenology of orbifold compactifications of the heterotic string within the context of supergravity effective theories.

Supersymmetric minisuperspace with non-vanishing fermion number [PDF]

open access: yes, 1995
The Lagrangean of $N=1$ supergravity is dimensionally reduced to one (time-like) dimension assuming spatial homogeneity of any Bianchi type within class A of the classification of Ellis and McCallum.

Superconformal vector multiplet self-couplings and generalised Fayet-Iliopoulos terms

open access: yesPhysics Letters B, 2019
As an extension of the recent construction of generalised Fayet-Iliopoulos terms in N=1 supergravity given in [1], we present self-interactions for a vector multiplet coupled to conformal supergravity.

Consistent truncations from the geometry of sphere bundles

open access: yesJournal of High Energy Physics, 2023
In this paper, we present a unified perspective on sphere consistent truncations based on the classical geometric properties of sphere bundles. The backbone of our approach is the global angular form for the sphere.

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.

SUSY breaking after inflation in supergravity with inflaton in a massive vector supermultiplet

open access: yesPhysics Letters B, 2016
We propose a limited class of models, describing interacting chiral multiplets with a non-minimal coupling to a vector multiplet, in curved superspace of N=1 supergravity. Those models are suitable for the inflationary model building in supergravity with

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.

A plethora of Type IIA embeddings for d = 5 minimal supergravity

open access: yesJournal of High Energy Physics, 2023
We construct multiple embeddings of all solutions of d = 5 minimal (un)gauged supergravity into massive Type IIA supergravity. The internal spaces and warpings of such embeddings are the same as those of the N $$ \mathcal{N} $$ = 1 supersymmetric (Mink5)

Supersymmetry and Supergravity: Phenomenology and Grand Unification

open access: yes, 1993
A survey is given of supersymmetry and supergravity and their phenomenology. Some of the topics discussed are the basic ideas of global supersymmetry, the minimal supersymmetric Standard Model (MSSM) and its phenomenology, the basic ideas of local ...
