Light Stops in the MSSM : Implications for Photino Dark Matter and Top Quark Decay
We consider the viability of the minimal supersymmetric standard model with a light (m ˜ t 1 < 45 GeV) stop. In order for its relic abundance to be cosmologically significant, the photino as dark matter must be quite close in mass to the stop, (m ˜ t 1 − m ˜ γ) ≃ 3 − 7 GeV. However, as we show, the photino despite its low mass is virtually undetectable by either direct or indirect means. We als...
متن کاملMsugra Dark Matter and the B Quark Mass
We extend the commonly used mSUGRA framework to allow complex soft terms. We show how these phases can induce large changes of the SUSY threshold corrections to the b quark mass and affect the neutralino relic density predictions of the model. We present some specific models with large SUSY phases which can accommodate the fermion electric dipole moment constraints and a neutralino relic densit...
متن کاملGravity-mediated (or composite) dark matter
Dark matter could have an electroweak origin, yet it could communicate with the visible sector exclusively through gravitational interactions. In a setup addressing the hierarchy problem, we propose a new dark-matter scenario where gravitational mediators, arising from the compactification of extra dimensions, are responsible for dark-matter interactions and its relic abundance in the Universe....
متن کاملDark-matter in gravity-mediated supersymmetry breaking
Astrophysicists have long been telling us that the universe is mostly made up of dark matter. Modern analyses, which take into account the subtleties of large scale structure formation, big bang nucleosynthesis, and observations of how galaxies rotate, have largely condensed to one common conclusion: most of the dark matter is probably stable weakly interacting massive particles (WIMPs) [1]. Wh...
متن کاملLight Scalar Top Quarks and Supersymmetric Dark Matter
A stable neutralino χ̃1, assumed to be the lightest supersymmetric particle, is a favored particle physics candidate for the cosmological Dark Matter. We study co– annihilation of the lightest neutralino with the lighter scalar top quark t̃1. We show that for natural values of the neutralino mass, ∼300 GeV, the χ̃1–t̃1 mass difference has to exceed ∼ 10 to 30 GeV if χ̃1 is to contribute significantl...
