Abstract: Dark matter accounts for most of the matter in the universe and plays a central role in shaping the universe's structure, yet it has never been directly observed. Revealing the nature of dark matter remains one of the greatest puzzles in the cosmos. One pioneering way to explore dark matter comes from probing the behavior of subatomic particles known as muons. The Muon g-2 experiment at Fermilab has achieved the most precise measurements of muon behavior in a magnetic field ever recorded, creating a new opportunity to search for dark matter. Such precision makes it possible to listen for extremely faint signals from interactions between dark matter and muons. This talk will highlight the challenge of detecting these subtle signals, and the broader impact that discovering dark matter could have on science and society.

Bio: Byungchul Yu is a PhD candidate at the University of Mississippi working on the Muon g-2 experiment at Fermilab. His work involves precision measurements of muons in a magnetic field. Building on this expertise, he is conducting the very first experimental search for dark matter interactions with muons. In addition to his research, he actively engages in science communication, connecting fundamental science with the broader community.
