太阳暗物质湮灭产生的Sub-GeV单能中微子在DUNE的定向散射
Directional Searches at DUNE for Sub-GeV Monoenergetic Neutrinos Arising from Dark Matter Annihilation in the Sun
摘要：
我们考虑使用的方向性在寻找单能亚GeV中微子所产生的衰变停止K介子，这可以产生的暗物质湮灭在太阳的核心。当这些中微子在中微子探测器上与原子核发生带电相互作用时，它们通常会射出一个质子，这个质子在正向方向上的峰值很高。这个轨迹的方向可以在DUNE测量，允许通过比较源上和源外事件率来区分信号和背景。我们发现，方向信息可以提高信号与背景的比例高达5倍。
英文摘要：
We consider the use of directionality in the search for monoenergetic sub-GeV neutrinos arising from the decay of stopped kaons, which can be produced by dark matter annihilation in the core of the Sun. When these neutrinos undergo charged-current interactions with a nucleus at a neutrino detector, they often eject a proton which is highly peaked in the forward direction. The direction of this track can be measured at DUNE, allowing one to distinguish signal from background by comparing on-source and off-source event rates. We find that directional information can enhance the signal to background ratio by up to a factor of 5.
