N=2 central charge superspace and a minimal supergravity multiplet [PDF]

open access: yes, 1998
We extend the notion of central charge superspace to the case of local supersymmetry. Gauged central charge transformations are identified as diffeomorphisms on the same footing as spacetime diffeomorphisms and local supersymmetry transformations.

Higher derivative extension of 6D chiral gauged supergravity [PDF]

open access: yes, 2012
Six-dimensional (1, 0) supersymmetric gauged Einstein-Maxwell supergravity is extended by the inclusion of a supersymmetric Riemann tensor squared invariant. Both the original model as well as the Riemann tensor squared invariant are formulated off-shell

Poisson–Lie transformations and generalized supergravity equations

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
In this paper we investigate Poisson–Lie transformation of dilaton and vector field $${\mathcal {J}}$$ J appearing in generalized supergravity equations. While the formulas appearing in literature work well for isometric sigma models, we present examples

On the Starobinsky model of inflation from supergravity [PDF]

open access: yesNuclear Physics B, 2013
We discuss how the higher-derivative Starobinsky model of inflation originates from N=1 supergravity. It is known that, in the old-minimal supergravity description written by employing a chiral compensator in the superconformal framework, the Starobinsky model is equivalent to a no-scale model with F-term potential.

Supergravity Models

open access: yes, 1993
Theoretical and experimental motivations behind supergravity grand unified models are described. The basic ideas of supergravity, and the origin of the soft breaking terms are reviewed. Effects of GUT thresholds and predictions arising from models possessing proton decay are discussed.

Gravitino properties in a conformal supergravity model [PDF]

open access: yesPhysical Review D, 2013
In the context of a conformal Supergravity (SUGRA) model in the Einstein frame, in which the (next to) minimal supersymmetric standard model can embedded naturally to produce chaotic inflation scenarios, we study properties of gravitino in the cases where it is stable or unstable.

Supersymmetric dS4 solutions in D = 11 supergravity

open access: yesJournal of High Energy Physics, 2022
The necessary and sufficient conditions for warped product dS4 solutions in D = 11 supergravity to be supersymmetric are determined. The Killing spinor is associated with two possible stabilizer groups, SU(3) and G2.

Gauge Theory and Supergravity Duality in the PP-Wave Background [PDF]

open access: yes, 2005
We test the matrix theory conjecture in the pp-wave by studying two-body interactions between gravitons and membranes. We compute the one-loop effective potential of matrix theory and compare it to the light cone Lagrangian of linearized supergravity. We

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 ...
