Toichiro Kinoshita

Toichiro Kinoshita (Japanese木 下 东 一郎, Kinoshita Toichiro; born January 23, 1925 in Tokyo) is a Japanese theoretical physicist.

Kinoshita studied physics at the University of Tokyo, where in 1947 he earned his bachelor's degree in 1952 and his doctorate. He then spent two years as a postdoctoral fellow at the Institute for Advanced Study and in 1954 at Columbia University. From 1954 he was at Cornell University, in 1955 as Assistant Professor, in 1958 as associate professor and from 1960 as full professor (from 1992 as Goldwin Smith Professor ) at the Newman Laboratory of Nuclear Studies, Cornell University. 1962/63 he was a Ford Fellow at CERN. In 1995 he retired. He was, inter alia, a visiting professor at the University of Tokyo, at CERN and at the National Laboratory for High Energy Physics KEK in Japan.

Kinoshita is known for its extensive precision calculations of fundamental quantities in quantum electrodynamics (including the electroweak theory and other corrections in the standard model) as the anomalous magnetic moments of leptons ( electron, muon ) and the spectrum of positronium ( the bound state of electron and positron ) and Myoniums that enabled a more detailed review of the theory with experiment. In addition, he was also involved in quantum chromodynamics and quarkonium spectroscopy ( with Estia Eichten, Kenneth Lane, Kurt Gottfried and others in the 1970s ).

In 2001 he had to admit in its calculation of the anomalous magnetic moment of the muon an error after experiments were in Brookhaven see a discrepancy in the 9th decimal place, what you thought was long, " new physics " to be able to track down. A group in Marseille checked then Kinoshita's account, as he himself, who traced the error to a sign error in the computer algebra program used.

In 1973/74 he was a Guggenheim Fellow. In 1990 he received the Sakurai Prize. He is a member of the National Academy of Sciences since 1991.
