Since 1987, Berkeley Physics has had the opportunity to bring world-renowned scientists to our campus to speak in honor of one of our greatest experimentalists, Emilio Segrè. The lecture series, which occurs each Fall, highlights trends, discoveries and groundbreaking research and is made possible through the generosity of the Raymond and Beverly Sackler Foundation.
Emilio Segre was truly one of the 20th century’s most distinguished physicists. Along with Owen Chamberlain, he won the Nobel Prize in 1959 for their discovery of the antiproton. Emilio Segre had been a student of Enrico Fermi in the late 1920s. He was also a faculty member with Berkeley Physics for more than five decades.
This year's Emilio Segré Lecture featuring Nobel Laureate Takaaki Kajita took place in the Chevron Auditorium at International House. Photos from the event can be viewed here. Professor Kajita's lecture on Neutrino Oscillations at the Super-Kamiokande Detector can be viewed below.
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.
