Susumu Okubo

Susumu Okubo (Japanese大 久保 进, Susumu Okubo, born 1930 in Japan) is a Japanese theoretical physicist.

Okubo studied from 1949 at the University of Tokyo (Bachelor 1952) and from 1954 at the University of Rochester, where he received his doctorate with Robert Marshak 1958. After that, he was a postdoctoral fellow 1959/60 at the University of Naples, 1960 /1 on the CERN shortly thereafter in Japan ( because he had problems getting a U.S. visa ) and from 1962 again at the Rochester University, where he became in 1964 Professor. In 1996 he retired.

Okubo deals primarily with elementary particle physics. He is best known for the Gell-Mann - Okubo mass formula for mesons and baryons in the quark model, ( 3) multiplets each other sets the masses of the members of SU in relationship.

In 2005 he received the Sakurai Prize of the American Physical Society, 1976 Nishina Prize in Japan and 2006, the Wigner Medal. In 1966 he was Guggenheim Fellow and 1969 Ford Fellow. He is a member of the American Physical Society and the American Mathematical Society.
