Electroweak Symmetry Breaking and Bottom-Top Yukawa Unification
TL;DR: In this paper, the feasibility of unification of the Yukawa couplings in the framework of the minimal supersymmetric standard model with (assumed) universal mass parameters at the unification scale and with radiative breaking of the electroweak symmetry was investigated.

Opening the window for electroweak baryogenesis
TL;DR: In this paper, an analysis of the electroweak phase transition in the Minimal Supersymmetric Standard Model, in the presence of light stops, has been performed and it has been shown that the order parameter v(Tc)/Tc can become significantly larger than one, for values of the Higgs and supersymmetric particle masses consistent with the present experimental bounds.

TL;DR: In this paper, the authors improved the theoretical prediction for the decay rate by summing very large radiative corrections to all orders in perturbation theory and extended the validity of the perturbative calculation to the large tan-beta regime.

Upper Bounds on Supersymmetric Particle Masses
TL;DR: In this paper, upper bounds on all superparticle masses as functions of the top quark mass are derived based on the "naturalness" criterion, which gives an objective criterion to test (or disprove) the idea of low energy supersymmetry, as implemented in supergravity models.
Journal ArticleDOI
Minimal Low-Energy Supergravity
TL;DR: In this paper, the authors use the renormalization group to relate parameters at the grand unification scale to their low energy values and show that renormalisation effects drive spontaneous breakdown of SU(2)×U(1) to U(1), for a top quark mass between 55 and 200 GeV.

The Neutralino relic density in minimal $N=1$ supergravity
Manuel Drees,Mihoko M. Nojiri +1 more
TL;DR: A large relic neutralino density is found, and the requirement that relic neutralinos do not overclose the Universe does not lead to upper bounds on SUSY-breaking parameters that are strictly valid for all combinations of parameters and of interest for existing or planned collider experiments.
Journal ArticleDOI
Quantum effects and SU(2)×U(1) breaking in supergravity gauge theories
TL;DR: In this article, the renormalization effects of SU(3)×SU(2)×U(1) models coupled to supergravity were studied at the one-loop level.

Grand Unification in Simple Supergravity
TL;DR: In this paper, the authors discuss aspects of grand unified theories (GUTs) combined with N = 1 local supersymmetry, interpreting the general form of simple supergravity theory as a phenomenological effective lagrangian applicable at energies less than the Planck mass.
