Supergravity backgrounds of the η-deformed AdS2 × S2 × T6 and AdS5 × S5 superstrings

Journal of High Energy Physics, 2019
We construct supergravity backgrounds for the integrable η-deformations of the AdS2 × S2 × T6 and AdS5 × S5 superstring sigma models. The η-deformation is governed by an R-matrix that solves the non-split modified classical Yang-Baxter equation on the ...

Symplectic Deformations of Gauged Maximal Supergravity [PDF]

, 2014
We identify the space of symplectic deformations of maximal gauged supergravity theories. Coordinates of such space parametrize inequivalent supergravity models with the same gauge group.

Consistent truncations from the geometry of sphere bundles

Journal of High Energy Physics, 2023
In this paper, we present a unified perspective on sphere consistent truncations based on the classical geometric properties of sphere bundles. The backbone of our approach is the global angular form for the sphere.

Supersymmetric minisuperspace with non-vanishing fermion number [PDF]

, 1995
The Lagrangean of $N=1$ supergravity is dimensionally reduced to one (time-like) dimension assuming spatial homogeneity of any Bianchi type within class A of the classification of Ellis and McCallum.

Superconformal vector multiplet self-couplings and generalised Fayet-Iliopoulos terms

Physics Letters B, 2019
As an extension of the recent construction of generalised Fayet-Iliopoulos terms in N=1 supergravity given in [1], we present self-interactions for a vector multiplet coupled to conformal supergravity.

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)

SUSY breaking after inflation in supergravity with inflaton in a massive vector supermultiplet

Physics Letters B, 2016
We propose a limited class of models, describing interacting chiral multiplets with a non-minimal coupling to a vector multiplet, in curved superspace of N=1 supergravity. Those models are suitable for the inflationary model building in supergravity with

Phenomenological Aspects of Heterotic Orbifold Models at One Loop

, 2003
We provide a detailed study of the phenomenology of orbifold compactifications of the heterotic string within the context of supergravity effective theories.

Warped compactification to de Sitter space [PDF]

, 2011
We explore in detail the prospects of obtaining a four-dimensional de Sitter universe in classical supergravity models with warped and time-independent extra dimensions, presenting explicit cosmological solutions of the $(4+n)$-dimensional Einstein ...
