Building models of inflation in no-scale supergravity [PDF]
, 2020 After reviewing the motivations for cosmological inflation formulated in the formalism of supersymmetry, we argue that the appropriate framework is that of no-scale supergravity.

Journal of High Energy Physics, 2021 Within the framework of N $$ \mathcal{N} $$ = 1 anti-de Sitter (AdS) supersymmetry in four dimensions, we derive superspin projection operators (or superprojectors). For a tensor superfield V α m α ⋅ n ≔ V α 1 … αm α ⋅ 1 … α ⋅ n $$ {\mathfrak{V}}_{\alpha

Component decompositions and adynkra libraries for supermultiplets in lower dimensional superspaces
Journal of High Energy Physics, 2021 We present Adynkra Libraries that can be used to explore the embedding of multiplets of component field (whether on-shell or partial on-shell) within Salam-Strathdee superfields for theories in dimension nine through four.

Jackiw-Teitelboim supergravity, minimal strings, and matrix models
, 2021 The author studies a family of two-dimensional Jackiw--Teitelboim (JT) supergravites, and, by using string theory techniques, he gives them a complete definition to all orders in the topological expansion.

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

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

Supergravity EFTs and swampland constraints [PDF]
Proceedings of Corfu Summer Institute 2022 "School and Workshops on Elementary Particle Physics and Gravity" — PoS(CORFU2022), 2023 In these proceedings, we review recent progress in analyzing the behavior of lower-dimensional supergravity theories when combined with swampland conjectures. We show that within supergravity the effectiveness and usefulness of swampland conjectures gets

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

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 ...
