Tōichirō Kinoshita

from Wikipedia, the free encyclopedia

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

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

Kinoshita is known for his extensive precision calculations of fundamental quantities in quantum electrodynamics (including the electroweak theory and other corrections from the Standard Model ) such as the anomalous magnetic moments of the leptons (electron, muon ) and the spectrum of positronium (the bound state of electron and positron ) and muoniums , which made it possible to test the theory more precisely with the experiment. In addition, he also dealt with quantum chromodynamics and quarkonium spectroscopy (with Estia Eichten , Kenneth Lane , Kurt Gottfried and others in the 1970s).

In 2001 he had to admit a mistake in his calculation of the anomalous magnetic moment of the muon after experiments in Brookhaven revealed a discrepancy in the 9th decimal place, whereupon it was believed that “new physics” had been discovered. A group in Marseille then checked Kinoshita's bill, as did the latter himself, who traced the error back 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 has been a member of the National Academy of Sciences since 1991 .
