报告内容：

The axion is a light pseudoscalar particle predicted by Steven Weinberg and Frank Wilczek to exist as a consequence of the Peccei–Quinn solution to the strong-CP problem. This light particle is a prime candidate to constitute the majority of all matter in the Universe. In this talk, I will discuss the potential of hunting for dark matter axions through 'Light shining through a wall' technique at Shanghai Coherent Light Facility (SCLF)--the most powerful x-ray free-electron laser to be in operation ~2025.
