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

Sneutrino as the lightest supersymmetric particle in B{sub 3} minimal supergravity models and signals at the LHC [PDF]

, 2008
We consider B{sub 3} minimal supergravity models where we have one lepton number violating L{sub i}Q{sub j}D{sub k} operator at the grand unification scale.

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.

Updated constraints on the minimal supergravity model [PDF]

Journal of High Energy Physics, 2006
We provide an up-to-date analysis of the parameter space of the minimal supergravity model (mSUGRA). Novel features include the new central value of the top quark mass, an improved calculation of the masses of the supersymmetric particles and the neutral Higgs bosons, constraints from b to s \ell^+ \ell^- decays, and a careful treatment of the most ...

Supersymmetry and supergravity models

Journal 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.

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 ...

Supersymmetry and Supergravity: Phenomenology and Grand Unification

, 1993
A survey is given of supersymmetry and supergravity and their phenomenology. Some of the topics discussed are the basic ideas of global supersymmetry, the minimal supersymmetric Standard Model (MSSM) and its phenomenology, the basic ideas of local ...

De sitter magnetic black hole dipole with a supersymmetric horizon

Journal of High Energy Physics, 2021
We find a new non BPS solution in N = 2 D = 4 gauged supergravity coupled to U(1) gauge fields and matter. It consists in a closed universe with two extremal black holes of equal size, surrounding two singularities.
