暗物质湮灭的μ子通量

Muon Fluxes From Dark Matter Annihilation

Arif Emre Erkoca, Mary Hall Reno, Ina Sarcevic

摘要:

本文计算了太阳核、地核暗物质湮灭和晕中暗物质湮灭产生的宇宙弥散中微子的μ子通量。我们考虑了与模型无关的直接中微子产生和由暗物质湮灭产生的τ衰变产生的次级中微子。我们说明了如何从暗物质湮灭μ子能量分布有一个非常不同的形状比μ子流量从大气中微子。我们认为向上μ介子通量,当μ介子在下面的岩石中创建的检测器,和所包含的流量时,μ介子创建(冰)检测器。我们将我们的结果与以前在文献中获得的结果进行了对比,说明了正确处理μ子传播和能量损失的重要性。我们评论中微子的味道依赖和他们的检测。

英文摘要:

We calculate the muon flux from annihilation of the dark matter in the core of the Sun, in the core of the Earth and from cosmic diffuse neutrinos produced in dark matter annihilation in the halos. We consider model-independent direct neutrino production and secondary neutrino production from the decay of taus produced in the annihilation of dark matter. We illustrate how muon energy distribution from dark matter annihilation has a very different shape than muon flux from atmospheric neutrinos. We consider both the upward muon flux, when muons are created in the rock below the detector, and the contained flux when muons are created in the (ice) detector. We contrast our results to the ones previously obtained in the literature, illustrating the importance of properly treating muon propagation and energy loss. We comment on neutrino flavor dependence and their detection.
