Query: Gamma-ray signatures for Kaluza-Klein dark matter   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-annihilation of Kaluza-Klein dark matter particles. For
comparison, we contrast this with the case of supersymmetry, where the
neutralino annihilation spectra take a very different form. In both cases we
find pronounced spectral signatures that could in principle be used to
distinguish between these two types of dark matter candidates already with
today's detector resolutions.
