Abstract:
At present, the ordinary matter including Neutrino consists only about 5% of the total energy density of the Universe, while the rest, 27% and 68%, are Dark Matter and Dark Energy, respectively. These dark components have not been seen directly though the normal ways, based on electric and magnetics interactions. In this talk, I will give a brief review on the ordinary matter, particularly Neutrino, as well as Dark Matter and Dark Energy. I will explain why the studies of Neutrino, Dark Matter, and Dark Energy are the frontiers of the current research on Particle Physics and Cosmology. In the end, I will present some future perspectives.
Brief Bio:
Chao-Qiang Geng received his Ph.D. degree in 1987 from Virginia Polytechnic Institute and State University, USA. He was the last student of Professor Robert E. Marshak, who was one of the founders for the theory of Weak Interactions. From 1987 to 1993, he was a Postdoctoral Research Associate in TRIUMF, Universite de Montreal and Iowa State University. He has been a faculty member at National Tsing Hua University since 1994. He has authored more than 280 papers in theoretical high energy physics. His research interests include preon, anomaly, axion, flavor physics and CP violation, and modified gravity. Currently, he has been working on the problems, related to neutrino masses, dark matter, dark energy, and the matter-antimatter asymmetry of the Universe.
