Abstract
We interpret recent IceCube results on searches for dark matter accumulated in the sun in terms of the lightest Kaluza-Klein excitation (assumed here to be the Kaluza-Klein photon, ), obtaining improved limits on the annihilation rate in the Sun, the resulting neutrino flux at the Earth and on the -proton cross-sections, for masses in the range 30--3000 GeV. These results improve previous results from IceCube in its 22-string configuration by up to an order of magnitude, depending on mass, but also extend the results to masses as low as 30 GeV.
