【中国新闻网】中国科学家证实80多年前量子力学理论预言 助力暗物质探测研究

Core Viewpoint - Chinese scientists have made a significant breakthrough in dark matter detection by directly observing the "Migdal effect," confirming a quantum mechanics theory proposed over 80 years ago, which may open new avenues for dark matter research [5][9]. Group 1: Research and Development - The research team, led by professors from the University of Science and Technology of China, developed a highly sensitive detection device that can capture the "Migdal effect" [5][8]. - The device combines a micro-structured gas detector with a pixel readout chip, functioning like a "camera" that can observe the release of electrons during atomic movements [8]. - The team successfully distinguished "Migdal events" from background noise, achieving a statistical significance exceeding five standard deviations, which is a gold standard in particle physics [8]. Group 2: Implications for Dark Matter Research - The discovery of six "Migdal events" serves as a calibration tool for future light dark matter detection experiments, providing critical data to enhance detection capabilities [9]. - The research team plans to optimize the detector's performance and expand observations of the "Migdal effect" across different elements, which will support the detection of lighter dark matter particles [9]. - The findings allow for the adjustment of analysis strategies in international dark matter detection projects, potentially improving sensitivity [9].
