Yōji Totsuka
Yōji Totsuka ( Japanese 戸 塚 洋 二 , Totsuka Yōji ; born March 6, 1942 in Fuji , Japan , † July 10, 2008 in Tokyo ) was a Japanese physicist .
Life
In 1965 Totsuka received his Bachelor of Science , 1967 his Masters and 1972 his PhD from the University of Tokyo . In the same year he became a visiting scholar at this university. He was then an associate professor from 1979 to 1987 and since then professor at the University of Tokyo.
Totsuka studied electron - positron collisions in experiments such as DASP at the DORIS accelerator from 1972 to 1976 and JADE at the PETRA accelerator from 1977 to 1980. From 1996 to 1998 Totsuka was a member of the Physics Research Committee (PRC), an international team Expert committee advising DESY on its high-energy physics research program.
In 1998 he was the coordinator of an experiment at the Japanese neutrino detectors Kamiokande and Super-Kamiokande , when the neutrino oscillation was experimentally confirmed for the first time . This proof showed that neutrinos are not massless, which had far-reaching consequences for the development of the standard model of elementary particle physics .
From 2003 to 2006 he was General Director of the Japanese Research Center for High Energy Physics KEK .
Totsuka died in July 2008 at the age of 66 from multiple organ failure as a result of cancer.
