论文摘要
到目前为止，弱相互作用的巨大颗粒（WIMP）仍然是最受欢迎的暗物质候选人之一。如果在太阳核心内被重力捕获，这些wimps可能会产生高能量中微子作为最终产物，以防它们在太阳核心处进行自我歼灭。在这项工作中，我们解决了所提出的KM3NET检测器上这种中微子的可检测性。对于通用暗物质方案以及选择了粒子暗物质的特定模型时，计算了这种中微子在KM3NET处的检测率的上限。在这项工作中，计算每种暗物质歼灭通道的情况下的MUON事件率的上限（例如，$ b \ bar {b}〜，w^+w^ - ，z \ bar {z} $）。这些上限也通过考虑使用Pandax-4T直接暗物质搜索实验获得的暗物质散射横截面来计算这些上限。
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.
