Chiral supergravity [PDF]

open access: yesJournal of High Energy Physics, 2009
We study the linearized approximation of N=1 topologically massive supergravity around AdS3. Linearized gravitino fields are explicitly constructed. For appropriate boundary conditions, the conserved charges demonstrate chiral behavior, so that chiral gravity can be consistently extended to chiral supergravity.

Supersymmetric AdS Solitons, Ground States, and Phase Transitions in Maximal Gauged Supergravity

open access: yesParticles, 2023
We review some recent soliton solutions in a class of four-dimensional supergravity theories. The latter can be obtained from black hole solutions by means of a double Wick rotation.

Multi-Field versus Single-Field in the Supergravity Models of Inflation and Primordial Black Holes

open access: yesUniverse, 2021
We review the models unifying inflation and Primordial Black Hole (PBH) formation, which are based on the modified (Starobinsky-type) supergravity. We begin with the basic (Starobinsky) inflationary model of modified gravity and its alpha-attractor-type ...

Holographic RG flows in $$N=4$$ N=4 SCFTs from half-maximal gauged supergravity

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
We study four-dimensional $$N=4$$ N=4 gauged supergravity coupled to six vector multiplets with semisimple gauge groups $$SO(4)\times SO(4)$$ SO(4)×SO(4) , $$SO(3,1)\times SO(3,1)$$ SO(3,1)×SO(3,1) and $$SO(4)\times SO(3,1)$$ SO(4)×SO(3,1) . All of these

On the Geometric Approach to the Boundary Problem in Supergravity

open access: yesUniverse, 2021
We review the geometric superspace approach to the boundary problem in supergravity, retracing the geometric construction of four-dimensional supergravity Lagrangians in the presence of a non-trivial boundary of spacetime.

Supergravity at colliders [PDF]

open access: yesPhysics Letters B, 2004
We consider supersymmetric theories where the gravitino is the lightest superparticle (LSP). Assuming that the long-lived next-to-lightest superparticle (NSP) is a charged slepton, we investigate two complementary ways to prove the existence of supergravity in nature.

Two-dimensional SCFTs from matter-coupled $$7D~N=2$$ 7DN=2 gauged supergravity

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
We study supersymmetric $$AdS_3\times M^4$$ AdS3×M4 solutions of $$N=2$$ N=2 gauged supergravity in seven dimensions coupled to three vector multiplets with $$SO(4)\sim SO(3)\times SO(3)$$ SO(4)∼SO(3)×SO(3) gauge group and $$M^4$$ M4 being a four ...

Supersymmetric RG flows and Janus from type II orbifold compactification

open access: yesEuropean Physical Journal C: Particles and Fields, 2017
We study holographic RG flow solutions within four-dimensional $$N=4$$ N = 4 gauged supergravity obtained from type IIA and IIB string theories compactified on $$T^6/\mathbb {Z}_2\times \mathbb {Z}_2$$ T 6 / Z 2 × Z 2 orbifold with gauge, geometric and ...

Supergravity at the boundary of AdS supergravity [PDF]

open access: yesPhysical Review D, 2009
We give a general analysis of AdS boundary conditions for spin-3/2 Rarita-Schwinger fields and investigate boundary conditions preserving supersymmetry for a graviton multiplet in AdS_4. Linear Rarita-Schwinger fields in AdS_d are shown to admit mixed Dirichlet-Neumann boundary conditions when their mass is in the range $0 \leq |m| < 1/2l_{AdS}$. We

New Black Hole Solutions in N = 2 and N = 8 Gauged Supergravity

open access: yesUniverse, 2021
We review a special class of N=2 supergravity model that interpolates all the single-dilaton truncations of the maximal SO(8) gauged supergravity.
