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 ...

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.

Journal of High Energy Physics, 2020 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.

Fine-tuning constraints on supergravity models [PDF]
Physics Letters B, 2000 We discuss fine-tuning constraints on supergravity models. The tightest constraints come from the experimental mass limits on two key particles: the lightest CP even Higgs boson and the gluino. We also include the lightest chargino which is relevant when universal gaugino masses are assumed. For each of these particles we show how fine-tuning increases

Non-relativistic three-dimensional supergravity theories and semigroup expansion method
Journal of High Energy Physics, 2021 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

Updated constraints on the minimal supergravity model [PDF]
Journal of High Energy Physics, 2006 We provide an up-to-date analysis of the parameter space of the minimal supergravity model (mSUGRA). Novel features include the new central value of the top quark mass, an improved calculation of the masses of the supersymmetric particles and the neutral Higgs bosons, constraints from b to s \ell^+ \ell^- decays, and a careful treatment of the most ...

Poisson–Lie transformations and generalized supergravity equations
European 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 destabilizing divergences in supergravity models [PDF]
Physics Letters B, 1995 We show that, for standard N=1 supergravity coupled to chiral matter, if the Kahler potential has no terms linear in chiral superfields then none are generated through quad. div. one--loop corrections. If however =0 and susy is spontaneously broken, linear terms are present and new linear terms may be generated due to nonrenormalizable couplings in K ...

The inflatino problem in supergravity inflationary models [PDF]
Physics Letters B, 2001 We consider the potential problems due to the production of inflatinos and gravitinos after inflation. Inflationary models with a single scale set by the microwave background anisotropies have a low enough reheat temperature to avoid problems with the thermal production of gravitinos.
