Abstract: Neutrinos were assumed to have no mass. It was predicted, however, if they have masses, they could change their type while they propagate. This phenomena is called neutrino oscillations, which was discovered by deep underground neutrino experiments. Dr. Takaaki Kajita will describe the discovery of neutrino oscillations and the implications of the small neutrino masses. The status and the future of neutrino oscillation studies will also be presented.
The Speaker: Takaaki Kajita is the Special University Professor at the University of Tokyo and the Director of the Institute for Cosmic Ray Research (ICRR) of the University of Tokyo. Kajita received his Ph.D. from the School of Science at the University of Tokyo in 1986 and has been conducting research in the Kamiokande and Super-Kamiokande detectors at the Kamioka Observatory in central Japan. In 1998, at the Neutrino International Conference held in Takayama, Gifu, he showed analysis results which provided strong evidence for atmospheric neutrino oscillations.
In 2015, he shared the Nobel Prize in Physics for his role in discovering atmospheric neutrino oscillations. Currently, he is the project leader for the KAGRA Project, aiming to explore gravitational wave astronomy.
