Weyl covariance, and proposals for superconformal prepotentials in 10D superspaces

Journal of High Energy Physics, 2021
Proposals are made to describe the Weyl scaling transformation laws of supercovariant derivatives ∇ A , the torsion supertensors T AB C , and curvature supertensors R ABc d in 10D superspaces. Starting from the proposal that an unconstrained supergravity

Primordial black holes and gravitational waves from nonminimally coupled supergravity inflation [PDF]

Physical Review D, 2022
We study the formation of primordial black holes and the generation of gravitational waves in a class of cosmological models that are direct supersymmetric analogs of the observationally favored nonminimally coupled Higgs inflation model.

Component actions of liberated N $$ \mathcal{N} $$ = 1 supergravity and new Fayet-Iliopoulos terms in superconformal tensor calculus

Journal of High Energy Physics, 2021
We explicitly compute the component action of certain recently discovered new N $$ \mathcal{N} $$ = 1 supergravity actions which enlarge the space of scalar potentials allowed by supersymmetry and also contain fermionic interaction terms that become ...

Reconstruction of α-attractor supergravity models of inflation [PDF]

, 2017
In this paper, we apply reconstruction techniques to recover the potential parameters for a particular class of single-field models, the $\ensuremath{\alpha}$-attractor (supergravity) models of inflation. This also allows us to derive the inflaton vacuum

AdS (super)projectors in three dimensions and partial masslessness

Journal of High Energy Physics, 2021
We derive the transverse projection operators for fields with arbitrary integer and half-integer spin on three-dimensional anti-de Sitter space, AdS3. The projectors are constructed in terms of the quadratic Casimir operators of the isometry group SO(2 ...

Supergravity models with 50–100 TeV scalars, supersymmetry discovery at the LHC, and gravitino decay constraints [PDF]

, 2017
We investigate the possibility of testing supergravity unified models with scalar masses in the range 50-100 TeV and much lighter gaugino masses at the Large Hadron Collider. The analysis is carried out under the constraints that models produce the Higgs

New duality-invariant models for nonlinear supersymmetric electrodynamics

Journal of High Energy Physics, 2023
We propose a new family of U(1) duality-invariant models for nonlinear N $$ \mathcal{N} $$ = 1 supersymmetric electrodynamics coupled to supergravity.

Symmetries of supergravity backgrounds and supersymmetric field theory

Journal of High Energy Physics, 2020
In four spacetime dimensions, all N $$ \mathcal{N} $$ = 1 supergravity-matter systems can be formulated in the so-called U(1) superspace proposed by Howe in 1981.
