太阳核暗物质湮灭中太阳中微子探测率的KM3NeT上界

KM3NeT upper bounds of detection rates of solar neutrinos from annihilations of dark matter at the solar core

摘要:

到目前为止,弱相互作用大质量粒子(WIMP)仍然是暗物质最受欢迎的候选者之一。如果这些弱相互作用粒子在太阳核心内被引力捕获,它们可能会产生高能中微子作为最终产物,以防它们在太阳核心发生自湮灭。在这项工作中,我们解决了这种中微子在拟议的KM 3 NeT探测器的可探测性。在KM 3 NeT的这种中微子的检测率的上限计算的情况下,一个通用的暗物质的情况下,也当粒子暗物质的特定模型被选择。在这项工作中,不同的湮灭暗物质质量的μ子事件率的上限计算的情况下,暗物质湮灭通道(例如$b\bar{b}~, W^+W^-, Z\bar{Z} $等)。这些上限也计算通过考虑暗物质散射截面使用上限从PandaX-4 T直接暗物质搜索实验获得。

英文摘要:

The Weakly Interacting Massive Particles (WIMPs) so far remain one of the most popular candidates for dark matter. If captured gravitationally inside the core of the Sun, these WIMPs may produce high energy neutrinos as the end product in case they undergo self annihilations at the solar core. In this work, we address the detectability of such neutrinos at the proposed KM3NeT detector. Upper bounds of the detection rate for such neutrinos at KM3NeT are computed for the case of a generic dark matter scenario and also when specific models for particle dark matter are chosen. In this work, upper bounds of muon event rates for different annihilating dark matter masses are computed for each of the cases of dark matter annihilation channels (e.g. $b\bar{b}~, W^+W^-, Z\bar{Z} $ etc). These upper bounds are also computed by considering the dark matter scattering cross-section using upper bounds obtained from PandaX-4T direct dark matter search experiment.
