Gamma-ray signatures for Kaluza-Klein dark matter
Lars Bergstrom, Torsten Bringmann, Martin Eriksson +1
The extra-dimensional origin of dark matter is a fascinating and nowadays often discussed possibility. Here, we present the gamma-ray signatures that are expected from the self-ann…
Gamma Rays from Heavy Neutralino Dark Matter
Lars Bergstrom, Torsten Bringmann, Martin Eriksson +1
We consider the gamma-ray spectrum from neutralino dark matter annihilations and show that internal bremsstrahlung of W pair final states gives a previously neglected source of pho…
Two photon annihilation of Kaluza-Klein dark matter
Lars Bergstrom, Torsten Bringmann, Martin Eriksson +1
We investigate the fermionic one-loop cross section for the two photon annihilation of Kaluza-Klein (KK) dark matter particles in a model of universal extra dimensions (UED). This…
Stability of Homogeneous Extra Dimensions
Torsten Bringmann, Martin Eriksson, Michael Gustafsson
In order not to be in conflict with observations it is crucial that extra dimensions, if they exist, are stable. It is shown that in the context of homogeneous extra dimensions, th…
Gamma Rays from Kaluza-Klein Dark Matter
Lars Bergstrom, Torsten Bringmann, Martin Eriksson +1
A TeV gamma-ray signal from the direction of the Galactic center (GC) has been detected by the H.E.S.S. experiment. Here, we investigate whether Kaluza-Klein (KK) dark matter annih…
Can homogeneous extra dimensions be stabilized during matter domination?
Torsten Bringmann, Martin Eriksson
We investigate cosmologies with homogeneous extra dimensions that can be described by generalised Friedmann-Robertson-Walker metrics and give a brief review on a general setup to d…
