Axion dark matter may couple to fermion spins through an effective oscillating magnetic field, the ``axion wind". Existing approaches for detecting axion wind via axion-electron coupling face sensitivity limitations due to the extremely weak pseudomagnetic field generated, typically a few times $10^{-18}$ tesla for $g_{ae} \sim 10^{-10}$. We propose to use ferrimagnetic flux concentrators to...
前人的工作大多默认太阳邻域暗物质的速度服从麦克斯韦-玻尔兹曼分布，而近些年来对银河系早期主并合事件的研究表明，真实的速度分布会一定程度偏离标准暗晕模型，这对暗物质直接探测实验中的年度调制效应和排除曲线有一定的影响，从而影响对实验结果的解读。
Searching for long-lived particles (LLPs) has emerged as an important research direction in the quest for physics beyond the Standard Model. Such searches can be performed at various terrestrial facilities including colliders, beam-dump experiments, and neutrino experiments. In this talk, I will focus on the ongoing Belle II experiment at the SuperKEKB collider in Tsukuba, Japan. I will...
