Kazuhiko Nishijima (西島 和彦 Nishijima Kazuhiko) (4 October 1926 – 15 February 2009) was a Japanese physicist who made significant contributions to particle physics. He was professor emeritus at the University of Tokyo and Kyoto University until his death in 2009.
He was born in Tsuchiura, Japan. He is most well known for his work on the Gell-Mann–Nishijima formula, and the concept of strangeness, which he called the "eta-charge" or "η-charge", after the eta meson (
η
).
He was nominated for the Nobel Prize in Physics in 1960 and 1961.
Nishijima was born in Tsuchiura, Japan on 4 October 1926. He obtained his diploma in physics at the University of Tokyo in 1948, and his PhD from Osaka University in 1955 for his thesis on the nuclear potential.
In 1950, while at Osaka University, Nishijima was hired by Yoichiro Nambu to work on the theory of strong interactions and of strange particles (then called V particles). While studying the decay of these particles, Nishijima developed, with Tadao Nakano, and independently of Murray Gell-Mann, a formula that would relate the quantum numbers of these particles, the Gell-Mann–Nishijima formula (or sometimes the NNG formula, for Nishijima, Nakano, and Gell-Mann).
