Event description: 

Astrophysical observation indicates that 68% of the Universe is made up of dark energy, 27% is dark matter, and the rest 5% is ordinary matter. Therefore, probing the dark components of the Universe is the most prominent subject in modern particle physics. One of the strong candidates of dark matter is the hypothetical particle called axions. The axion has been postulated to solve the strong-CP problem in quantum chromodynamics. The axion is also an ideal dark matter candidate who would have been produced during the Big Bang. The discovery of the axion will resolve the strong-CP problem, and the discovery of dark matter will revolutionize our understanding of the Universe. There are tremendous experimental efforts to discover the axion dark matter. In this seminar, I will discuss recent experimental results of a dark matter axion search using a haloscope with an 18T High-Temperature Superconducting Magnet and a Josephson Parametric Converter.
