Lecture Theatre, Hong Kong Central Library

Prof. Chu Ming-chung

The speaker obtained his B.Sc. and PhD degrees both at California Institute of Technology (Caltech).  He held research positions at MIT and Caltech before joining the Chinese University of Hong Kong in 1995.  His current research interest includes astrophysics, cosmology, and particle physics.  In particular, he has been the PI of the Hong Kong team of the Daya Bay Reactor Neutrino Experiment, which has discovered a new kind of neutrino oscillation that bears important implications for cosmology and particle physics.

In recent years, advances in cosmological observation have led to a large volume of precision data. As a result, physicists have gained tremendous insight into the content and evolution of the universe. We now know that the normal matter we are familiar with accounts for only a small fraction of the total mass-energy of the universe. Instead, ghost particles – particles that have almost no interaction with ordinary matter – dominate, and they are essential for understanding how the universe evolves to its present state. In this lecture, Prof. Chu Ming-chung will introduce the physics of ghost particles and their roles in some important outstanding problems in cosmology. Recently, scientists have made important breakthroughs in the study of neutrinos, a class of ghost particles. Prof. Chu will also discuss a related research project that a CUHK group of researchers has been actively participated in, the Daya Bay Neutrino Oscillation Experiment.
