Hunting the Ghost Particles in the Dark Universe
Prof. Yuhsin Tsai
Department of Physics
University of Notre Dame
Neutrinos were first detected more than six decades ago, and are among the most abundant particles in the universe. However, they remain among the most mysterious. How heavy are they? How long can they live? Can they interact with each other with a yet-unknown force? These questions are usually difficult to answer using particle detectors on earth. Prof. Yushin Tsai, the Tom and Carolyn Marquez assistant professor of physics, will describe how physicists can use the whole universe as a particle detector to hunt for information about these ghost particles in nature.
