Professor emeritus of KEK - High Energy Accelerator Research Organization (KEK), Tsukuba, Japan.
Executive Director of the Japan Society for the Promotion of Science (JSPS)
After receiving his Ph.D at the Graduate School of Nagoya University, Kobayashi started his career as a research associate at Kyoto University. During his work at Kyoto University, Kobayashi published a paper "CP Violation in the Renormalizable Theory of Weak Interaction", written with Toshihide Maskawa, which is the second most cited high energy physics paper of all time as of 2007.
Kobayashi and Maskawa explained the broken symmetry of matter and antimatter within the framework of the Standard Model, the basic theory of how the universe operates, by predicting the existence of a third generation of quarks then unknown. CP Violation, meaning symmetry breaking of charge and parity, was precisely confirmed by the two particle detectors: BaBar at Stanford Linear Accelerator Center (SLAC), USA, and Belle at KEK, Japan.
1979 : Nishina Memorial Prize (Nishina Memorial Foundation)
1985 : J.J.Sakurai Prize (American Physical Society)
1985 : The Japan Academy Prize (The Japan Academy)
1995 : Asahi Prize (Asahi Shinbun)
1995 : Chunichi Cultural Prize (Chunichi Shimbun)
2001 : The Person of Cultural Merit Award (Agency for Cultural Affairs)
2008 : Nobel Prize in Physics for the discovery of the origin of the broken symmetry which predicts the existence of at least three families of quarks in nature. He shared the award with Toshihide Maskawa, Professor of Kyoto Sangyo University in Kyoto, and Yoichiro Nambu, Professor Emeritus of University of Chicago, who was awarded the prize for the discovery of the mechanism of spontaneous symmetry breaking in subatomic physics.
