Z ′ Signals from Kaluza - Klein Dark Matter
In a minimal model of universal extra dimensions the lightest Kalzua-Klein particle is neutral and stable because of Kaluza-Klein parity conservation and it is a dark matter candidate. The corresponding level 2 mode of the lightest Kaluza-Klein particle can be detected via KK number violating decays to Standard Model particles. The expected sensitivity to second level Kaluza-Klein modes of neut...
متن کاملKaluza-Klein dark matter.
We propose that cold dark matter is made of Kaluza-Klein particles and explore avenues for its detection. The lightest Kaluza-Klein state is an excellent dark matter candidate if standard model particles propagate in extra dimensions and Kaluza-Klein parity is conserved. We consider Kaluza-Klein gauge bosons. In sharp contrast to the case of supersymmetric dark matter, these annihilate to hard ...
متن کاملIndirect Searches for Kaluza-klein Dark Matter∗
In this talk, we discuss the potential for the indirect detection of Kaluza-Klein dark matter using neutrino telescopes and cosmic positron experiments. We find that future kilometer-scale neutrino telescopes, such as IceCube, as well as future experiments capable of measuring the cosmic positron spectrum, such as PAMELA and AMS-02, will be quite sensitive to this scenario. Current data from th...
متن کاملHigh-energetic Cosmic Antiprotons from Kaluza-Klein Dark Matter
The lightest Kaluza-Klein particle (LKP) in models with universal extra dimensions is an interesting dark matter candidate that has recently received great attention. Here, we investigate the antiproton flux from LKP annihilations in the galactic halo. In our analysis we include different halo density profiles and allow for part of the dark matter to be concentrated in ’clumps’ rather than bein...
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.
