AdS (super)projectors in three dimensions and partial masslessness
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 ...

Scrutinizing supergravity models through neutrino telescopes [PDF]
Galactic halo neutralinos ($ $) captured by the Sun or Earth produce high-energy neutrinos as end-products of various annihilation modes. These neutrinos can travel from the Sun or Earth cores to the neighborhood of underground detectors (``neutrino telescopes") where they can interact and produce upwardly-moving muons. We compute these muon fluxes in

New duality-invariant models for nonlinear supersymmetric electrodynamics
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
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.

For the first time in the physics literature, the Lorentz representations of all 2,147,483,648 bosonic degrees of freedom and 2,147,483,648 fermionic degrees of freedom in an unconstrained eleven dimensional scalar superfield are presented.

Chromo-natural inflation in Supergravity
We present supergravity realizations of chromo-natural inflationary models. We show that by using superpotentials with “imaginary” holomorphic functions of the inflaton one can obtain effective theories of inflation that are also consistent truncations ...

Non-relativistic three-dimensional supergravity theories and semigroup expansion method
In this work we present an alternative method to construct diverse non-relativistic Chern-Simons supergravity theories in three spacetime dimensions. To this end, we apply the Lie algebra expansion method based on semigroups to a supersymmetric extension

Poisson–Lie transformations and generalized supergravity equations
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
