Yoji Totsuka

Yoji Totsuka (Japanese戸 冢 洋 二, Yoji Totsuka, born March 6, 1942 in Fuji, Japan, † July 10, 2008 in Tokyo ) was a Japanese physicist.

Life

In 1965, Totsuka received a Bachelor of Science in 1967 and his master's degree in 1972 his Ph.D. at the University of Tokyo. In the same year he was a visiting scientist at the university. Subsequently, he was an associate professor from 1979 to 1987 and since then a professor at the University of Tokyo.

Totsuka examined electron-positron collisions in experiments such as DASP at the DORIS accelerator in the years 1972-1976 and JADE at PETRA accelerator 1977 until 1980. Between 1996 and 1998 Totsuka was a member of the Physics Research Committee (PRC), an international board panel of experts that advises DESY for his high-energy physics research program.

In 1998, he was the coordinator of an experiment on the Japanese neutrino detectors Kamiokande and Super - Kamiokande, as the neutrino was experimentally confirmed for the first time. This evidence showed that neutrinos are massless not know what for the development of the Standard Model of elementary particle physics had far-reaching consequences.

From 2003 to 2006 he was Director General of the Japanese Research Center for High Energy Physics KEK

Totsuka died aged 66 in July 2008 to multi-organ failure as a result of cancer.
