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

Supergravity based inflation models: a review

, 2011
In this review, we discuss inflation models based on supergravity. After explaining the difficulties in realizing inflation in the context of supergravity, we show how to evade such difficulties. Depending on types of inflation, we give concrete examples,

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.

Quintessence with two energy scales [PDF]

, 2001
We study quintessence models using low energy supergravity inspired from string theory. We consider effective supergravity with two scales m_S, the string scale, and m_PL, the Planck scale and show that quintessence naturally arises from a supersymmetry ...

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

Physical 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 ...

Hyper-dilaton Weyl multiplet of 4D, N $$ \mathcal{N} $$ = 2 conformal supergravity

Journal of High Energy Physics, 2022
We define a new dilaton Weyl multiplet of N $$ \mathcal{N} $$ = 2 conformal supergravity in four dimensions. This is constructed by reinterpreting the equations of motion of an on-shell hypermultiplet as constraints that render some of the fields of the ...

Scrutinizing supergravity models through neutrino telescopes. [PDF]

Physical 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 ...

Oxide Interface of Gallium‐Based Liquid Metals: Beneficial Bridge or Hidden Risk?

ChemistryEurope, EarlyView.
Discussion on oxide interfaces in gallium‐based liquid metals have concentrated on their properties, behaviors, and related applications. However, the molecular mechanisms underlying effects, as well as the differences between the presence and absence of the oxide layer, have been less thoroughly discussed.

Relic density of neutralino dark matter in supergravity models [PDF]

We calculate the relic density $({\ensuremath{\Omega}}_{{\ensuremath{\chi}}_{1}^{0}}{h}^{2})$ of neutralino dark matter in supergravity models with radiative electroweak symmetry breaking, for values of the Higgs sector parameter $\mathrm{tan}\ensuremath{
