Hypermultiplet gaugings and supersymmetric solutions from 11D and massive IIA supergravity on H ( p , q ) spaces. [PDF]

Eur Phys J C Part Fields, 2018
Supersymmetric $\,\textrm{AdS}_{4}\,$, $\,\textrm{AdS}_{2} \times \Sigma_{2}\,$ and asymptotically AdS$_{4}$ black hole solutions are studied in the context of non-minimal $\,\mathcal{N}=2\,$ supergravity models involving three vector multiplets (STU ...

N=2 supergravity models with stable de Sitter vacua [PDF]

, 2003
In the present talk I shall review the construction of N=2 supergravity models exhibiting stable de Sitter vacua. These solutions represent the first instance of stable backgrounds with positive cosmological constant in the framework of extended ...

SUSY flavor structure of generic 5D supergravity models [PDF]

, 2012
We perform a comprehensive and systematic analysis of the SUSY flavor structure of generic 5D supergravity models on S1/Z2 with multiple Z2-odd vector multiplets that generate multiple moduli.

$R_b$ in supergravity models [PDF]

, 1995
We compute the supersymmetric contribution to $R_{b}\equiv \Gamma (Z\to b{\bar b})/\Gamma (Z\to {\rm hadrons})$ in a variety of supergravity models. We find $R^{\rm susy}_b\lsim0.0004$, which does not shift significantly the Standard Model prediction

Supergravity Models for 3+1 Dimensional QCD [PDF]

, 1999
The most general black M5-brane solution of eleven-dimensional supergravity (with a flat R^4 spacetime in the brane and a regular horizon) is characterized by charge, mass and two angular momenta.

Supergravity solution-generating techniques and canonical transformations of σ-models from O(D, D) [PDF]

Journal of High Energy Physics, 2021
Within the framework of the flux formulation of Double Field Theory (DFT) we employ a generalised Scherk-Schwarz ansatz and discuss the classification of the twists that in the presence of the strong constraint give rise to constant generalised fluxes ...

Testing primordial black holes as dark matter in supergravity from gravitational waves

Physics Letters B, 2021
We explore the Gravitational Waves (GW) phenomenology of a simple class of supergravity models that can explain and unify inflation and Primordial Black Holes (PBH) as Dark Matter (DM).

Supergravities and branes from Hilbert-Poincaré series

Journal of High Energy Physics, 2023
The Molien-Weyl integral formula and the Hilbert-Poincaré series have proven to be powerful mathematical tools in relation to gauge theories, allowing to count the number of gauge invariant operators.
