Description
PandaX实验位于四川锦屏山地下约2400米，利用大体量液态氙探测器开展多物理目标研究。在低本底、高灵敏的条件下，PandaX结合大体积、高能量分辨率和严格背景抑制策略，不仅实现了暗物质搜索，也具备对太阳中微子进行探测的能力，为检验太阳模型及探测新物理信号提供重要实验基础。本报告汇报利用 PandaX-4T 数据开展的太阳中微子测量结果。该分析通过利用能谱信息，在探测器相关本底和放射性本底存在的情况下研究太阳中微子信号，进一步结合事例拓扑信息，以约束材料本底成分。未来，PandaX-20T升级版探测器的投运将显著提升灵敏度，有望进一步推动太阳中微子研究，并实现与暗物质探测和双β衰变的协同科学目标。
The PandaX experiment, located about 2400 meters underground at the China Jinping Underground Laboratory, uses large-scale liquid-xenon detectors for low-background, high-sensitivity multi-physics studies. With its large target mass and strict background suppression, PandaX is capable of both dark matter searches and solar neutrino measurements. This report presents solar neutrino results based on PandaX-4T data. The analysis uses spectral and event-topology information to study solar neutrino signals and constrain detector-related, radioactive, and material backgrounds. The future PandaX-20T detector is expected to further improve sensitivity and strengthen the connection between solar neutrino studies, dark matter searches, and double-beta decay research.
