Extra-dimensions and Dark Matter
In this paper we study the general scenario of an effective theory coming from the com-pactification of a higher dimensional theory in a string inspired setting. This leads to gauge coupling unification at an intermediate mass scale. After having computed all the threshold corrections (due to Kaluza-Klein modes) to the running of the couplings of the MSSM we embark in a detailed phenomenologica...
متن کاملGravitons and Dark Matter in Universal Extra Dimensions
Models of Universal Extra Dimensions (UED) at the TeV scale lead to the presence of Kaluza Klein (KK) excitations of the ordinary fermions and bosons of the Standard Model that may be observed at hadron and lepton colliders. A conserved discrete symmetry, KK-parity, ensures the stability of the lightest KK particle (LKP), which, if neutral, becomes a good dark matter particle. It has been recen...
متن کاملSupersymmetry Breaking, Extra Dimensions and Neutralino Dark Matter
We show some phenomenological implications for the dark matter problem of a class of models with deflected anomaly mediated supersymmetry breaking in the context of the MSSM. This scenario can be naturally embedded in a brane world model with one compactified extra dimension. It turns out that in these models the neutralino is still the LSP and so a good candidate as cold dark matter. We found ...
متن کاملKaluza–Klein Dark Matter from Deconstructed Universal Extra Dimensions
We consider Kaluza–Klein dark matter from deconstructed or latticized universal extra dimensions and study in this model the positron flux from Kaluza–Klein dark matter annihilation in the galactic halo.
متن کاملSpinless photon dark matter from two universal extra dimensions
We explore the properties of dark matter in theories with two universal extra dimensions, where the lightest Kaluza-Klein state is a spin-0 neutral particle, representing a six-dimensional photon polarized along the extra dimensions. Annihilation of this ‘spinless photon’ proceeds predominantly through Higgs boson exchange, and is largely independent of other Kaluza-Klein particles. The measure...
