IceCube上的暗物质场景

Dark Matter scenarios at IceCube

Marco Chianese

摘要:

最近IceCube合作组对6年上升μ介子中微子的研究和多信使分析支持了TeV-PeV中微子扩散通量的双分量假设。根据天体物理幂律的陡度,冰立方数据中的过剩显示在能量范围10-100 TeV(低能过剩)或PeV(高能过剩)。在这两种情况下,我们的特点是一个双组分中微子通量衰变暗物质粒子提供了一个贡献的冰立方观测。

英文摘要:

The recent study on the the 6-year up-going muon neutrinos by the IceCube Collaboration and the multi-messenger analyses support the hypothesis of a two-component scenario explaining the diffuse TeV-PeV neutrino flux. Depending on the steepness of the astrophysical power-law, an excess in the IceCube data is shown in the energy range 10-100 TeV (low-energy excess) or at PeV (high-energy excess). In both cases, we characterize a two-component neutrino flux where decaying Dark Matter particles provide a contribution to the IceCube observations.
