冰立方中微子观测站的建设实际上已经终止。在撰写本文时，预计将有86个字符串中有79个字符串获取数据，我们距离完成部署还有一个季节。然而，该探测器自2006年以来一直在不同的部分配置中获取数据。我们已经评估了这些数据的证据暗物质湮灭在太阳中，在银河系中心和银河系晕，寻找一个多余的中微子通量超过预期的大气中微子背景。本文回顾了利用冰立方的22和40弦结构对WIMP、Kaluza-Klein模和超重候选者（BZZILLAS）进行暗物质搜索的结果。结果以μ子通量极限的形式呈现，对候选者的质子自旋相关截面的约束，以及对自湮没截面的约束。这些结果是在直接搜索和空间搜索的背景下提出的。
The construction of the IceCube neutrino observatory is practically terminated. At the time of this writing, and with 79 strings taking data out of the 86 foreseen, we are one deployment season away from completion. The detector, however, has been taking data since 2006 in different partial configurations. We have evaluated these data for evidence of dark matter annihilations in the Sun, in the Galactic Center and in the Galactic Halo, searching for an excess neutrino flux over the expected atmospheric neutrino background. This contribution reviews the results of dark matter searches for WIMPs, Kaluza-Klein modes and superheavy candidates (Simpzillas), using the 22and 40-string configurations of IceCube. The results are presented in the form of muon flux limits, constrains on the candidates’ spin-dependent cross-section with protons, and constrains in the self-annihilation cross section. These results are presented in the context of direct searches and searches in space.
