我们提出了第一个冰立方搜索暗物质湮灭的信号在银河系中使用所有风味中微子诱导的粒子级联。分析的重点是冰立方的DeepCore子探测器，并使用周围的冰立方字符串作为否决区域，以便在DeepCore卷中选择启动事件。在2011-2012年期间，我们使用了来自IceCube的329天的实时数据，这些数据由86个管柱组成。没有发现中微子过量，最终结果与背景假设相符。从这一无效结果中，我们得出了候选暗物质质量范围从30 GeV到10 TeV的速度平均自湮灭截面的上限，假设两者都是cuspy和平核暗物质晕剖面。对于在200gev到10tev之间的暗物质，结果比之前所有的冰立方实验结果都有所改善，达到了10⁻²³cm³s⁻¹的水平，这取决于假设的湮灭通道，对于一个尖头的NFW剖面。分析表明，尽管与冰立方中的μ子轨道相比，级联的角分辨率本质上更差，但全风味搜索与μ子通道搜索具有竞争力。
We present the first IceCube search for a signal of dark matter annihilations in the Milky Way using all-flavour neutrino-induced particle cascades. The analysis focuses on the DeepCore sub-detector of IceCube, and uses the surrounding IceCube strings as a veto region in order to select starting events in the DeepCore volume. We use 329 live-days of data from IceCube operating in its 86-string configuration during 2011-2012. No neutrino excess is found, the final result being compatible with the background-only hypothesis. From this null result, we derive upper limits on the velocity-averaged self-annihilation cross-section,, for dark matter candidate masses ranging from 30 GeV up to 10 TeV, assuming both a cuspy and a flat-cored dark matter halo profile. For dark matter masses between 200 GeV and 10 TeV, the results improve on all previous IceCube results on, reaching a level of 10⁻²³ cm³ s⁻¹, depending on the annihilation channel assumed, for a cusped NFW profile. The analysis demonstrates that all-flavour searches are competitive with muon channel searches despite the intrinsically worse angular resolution of cascades compared to muon tracks in IceCube.
