我们调查的卡鲁扎-克莱因暗物质的间接检测的前景，专注于第一卡鲁扎-克莱因激发的超荷规范玻色子${B}^{（1）}$在银河系晕湮灭辐射，特别是我们估计中微子，γ射线和同步辐射通量。将预测的通量与观测数据相比较，我们能够约束${B}^{（1）}$质量（从而约束紧化尺度）。这些限制取决于暗物质密度分布所采用的具体模型。对于Navarro、Frenk和白色剖面，同步辐射的分析将${B}^{（1）}$质量的下限定为300 GeV。
We investigate prospects for indirect detection of Kaluza-Klein dark matter, focusing on the annihilation radiation of the first Kaluza-Klein excitation of the hypercharge gauge boson ${B}^{(1)}$ in the galactic halo; in particular we estimate neutrino, gamma-ray and synchrotron fluxes. Comparing the predicted fluxes with observational data we are able to constrain the ${B}^{(1)}$ mass (and therefore the compactification scale). The constraints depend on the specific model adopted for the dark matter density profile. For a Navarro, Frenk, and White profile the analysis of synchrotron radiation puts a lower bound on the ${B}^{(1)}$ mass of the order of $\ensuremath{\simeq}300\mathrm{GeV}.$
