Susumu Okubo (大久保 進, Ōkubo Susumu, 2 March 1930 – July 17, 2015)[1] was a Japanese theoretical physicist at the University of Rochester. Ōkubo worked primarily on elementary particle physics. He is famous for the Gell-Mann–Okubo mass formula for mesons and baryons in the quark model; this formula correctly predicts the relations of masses of the members of SU(3) multiplets in terms of hypercharge and isotopic spin.[2][3] Ōkubo died in July 2015.[1]
Ōkubo began study at the University of Tokyo in 1949 and received his bachelor's degree there in 1952. He became a graduate student at the University of Rochester in 1954, where he earned his PhD in 1958 with David Feldman as thesis advisor.[1] Afterwards, he was a postdoc in 1959/60 at the University of Naples, in 1960/61 at CERN, and then in 1962 began researching again at the University of Rochester, where he became a professor in 1964 and retired in 1996 as an emeritus professor.
