On jordanian deformations of AdS_5 and supergravity [PDF]
J. Phys. A: Math. Theor. 49 (2016) 434006, 2016 We consider various homogeneous Yang-Baxter deformations of the AdS_5 x S^5 superstring that can be obtained from the eta-deformed superstring and related models by singular boosts. The jordanian deformations we obtain in this way behave similarly to the eta-deformed model with regard to supergravity: T dualizing the classical sigma model it is ...

Five-dimensional Superfield Supergravity [PDF]
, 2007 We present a projective superspace formulation for matter-coupled simple supergravity in five dimensions. Our starting point is the superspace realization for the minimal supergravity multiplet proposed by Howe in 1981.

General F-theory models with tuned (SU(3) × SU(2) × U(1))/ℤ6 symmetry
Journal of High Energy Physics, 2020 We construct a general form for an F-theory Weierstrass model over a general base giving a 6D or 4D supergravity theory with gauge group (SU(3) × SU(2) × U(1))/ℤ6 and generic associated matter, which includes the matter content of the standard model. The

A plethora of Type IIA embeddings for d = 5 minimal supergravity
Journal of High Energy Physics, 2023 We construct multiple embeddings of all solutions of d = 5 minimal (un)gauged supergravity into massive Type IIA supergravity. The internal spaces and warpings of such embeddings are the same as those of the N $$ \mathcal{N} $$ = 1 supersymmetric (Mink5)

Noncompact gaugings, chiral reduction and dual sigma models in supergravity [PDF]
Class.Quant.Grav.23:2803-2832,2006, 2005 We show that the half-maximal SU(2) gauged supergravity with topological mass term admits coupling of an arbitrary number of n vector multiplets. The chiral circle reduction of the ungauged theory in the dual 2-form formulation gives N=(1,0) supergravity in 6D coupled to 3p scalars that parametrize the coset SO(p,3)/SO(p)x SO(3), a dilaton and (p+3 ...

Mapping 6D N = 1 supergravities to F-theory [PDF]
, 2009 We develop a systematic framework for realizing general anomaly-free chiral 6D supergravity theories in F-theory. We focus on 6D (1, 0) models with one tensor multiplet whose gauge group is a product of simple factors (modulo a finite abelian group) with

Minimal Constrained Supergravity [PDF]
, 2016 We describe minimal supergravity models where supersymmetry is non-linearly realized via constrained superfields. We show that the resulting actions differ from the so called "de Sitter" supergravities because we consider constraints eliminating directly the auxiliary fields of the gravity multiplet.

Complex supergravity quintessence models confronted with Sn Ia data [PDF]
Phys.Lett.B634:5-8,2006, 2005 A class of supergravity inspired quintessence models is studied by comparing to cosmological data. The set of considered models includes several previously studied quintessential potentials, as well as the $\Lambda$CDM model. We find that even though the commonly studied supergravity inspired quintessence models fit the data better than the $\Lambda ...
