Supersymmetry and supergravity models

open access: yesJournal of Physics G: Nuclear and Particle Physics, 1998
In this paper a review of the present status of supersymmetric (SUSY) and supergravity (SUGRA) models is presented, emphasizing the ambiguities one encounters in constructing a SUSY or SUGRA version of the standard model.

Classical Yang-Baxter equation from β-supergravity

open access: yesJournal of High Energy Physics, 2019
Yang-Baxter deformations of superstring σ-models have recently inspired a supergravity solution generating technique. Using the open/closed string map and a Killing bi-vector as a deformation parameter, new solutions can be built, such that the ...

Scrutinizing supergravity models through neutrino telescopes. [PDF]

open access: yesPhysical Review D, Particles and fields, 1993
Galactic halo neutralinos ([chi]) 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 ...

Unification of Conformal and Fuzzy Gravities With Internal Interactions Resulting in SO(10) and a Possible Probe Through Stochastic Gravitational Wave Background

open access: yesFortschritte der Physik, EarlyView.
Abstract The unification of conformal and fuzzy gravities with internal interactions is based on the facts that i) the tangent group of a curved manifold and the manifold itself do not necessarily have the same dimensions and ii) both gravitational theories considered here have been formulated in a gauge theoretic way.

Accurate neutralino relic density computations in supergravity models. [PDF]

open access: yesPhysical Review D, Particles and fields, 1993
We investigate the question of the proper thermal averaging of neutralino annihilation amplitudes which possess poles and thresholds, as they impact on the calculated neutralino relic density and therefore on the cosmological viability of supersymmetric ...

Supergravity and In‐Situ Evaporation Induced Well‐Aligned and Self‐Crosslinked 2D Material‐Based Thin Films

open access: yesAdvanced Materials Interfaces, Volume 12, Issue 13, July 14, 2025.
The supergravity and in‐situ evaporation are utilized to produce GO thin films with a record‐high mechanical strength of 540 MPa. The supergravity confines the 2D flakes within a very thin layer and creates a large all‐directional shear stress to induce the superalignment, while in‐situ evaporation accelerates the dehydration and facilitates the ester ...

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

open access: yes, 2003
In this paper, we 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 theframework of extended ...

Vibration‐Induced Stabilization of Lithium Anodes: Synergistic Effects of Morphological and SEI Evolution

open access: yesAdvanced Science, Volume 12, Issue 26, July 10, 2025.
This study, for the first time, highlights the marvelous effect of mechanical vibration on the performance of lithium metal batteries. The authors demonstrate that vibration enhances the performance of lithium metal anodes through a synergistic effect: surface flattening at the macroscale and the formation of an interfacial layer that facilitates fast ...
