Jayme Tiomno

Jayme Tiomno ( born April 16, 1920 in Rio de Janeiro, † January 12, 2011 ) was a Brazilian experimental and theoretical physicist who dealt with elementary particle physics and general relativity.

Tiomno was the son of Jewish immigrants from Russia. He studied medicine in Rio, before he turned to under the influence of Mário 's mountain at the University of Sao Paulo physics. 1948 to 1950 he studied at Princeton University among others, John Archibald Wheeler. He has published with Wheeler and Chen Ning Yang and completed his PhD in 1950 under Eugene Wigner ( physics and neutrino double beta decay ), as Wheeler in 1949 went to Paris. He was in 1949 with José Leite Lopes and César Lattes one of the founders of the Centro Brasileiro de Pesquisas físicas ( CBPF ) in Rio, where he was professor from 1952. In 1965 he worked on the physics faculty of the newly founded University of Brasilia. 1967 to 1969 he was professor at the University of Sao Paulo. While the military government in Brazil, he was released in 1969. 1973 to 1980 he taught as a professor at the Catholic University in Rio.

1959/60 he was a visiting scientist at Imperial College London and in 1967 at the ICTP in Trieste. 1971/72 he was at the Institute for Advanced Study.

1947 to 1949 he undertook fundamental work on decays with muons in Princeton (according to him and Wheeler is the Tiomno -Wheeler triangle named) and hit Wheeler independence of electron and muon neutrinos before. In the 1950s, he dealt among other things with parity violation. and the general form of the weak interaction ( with CN Yang 1950). Work with Wheeler and Yang were the first who set a universal form of the weak interaction in the proton, neutron, electron and muon system. In this context, he also dies ( see Dirac matrices ) in the formulation of the weak interaction. In 1957 he proposed an early unified theory of elementary particles before ( with the seven -dimensional orthogonal group as symmetry).

In 1960 he suggested the existence of resonances in meson.

In 1951, he was with W. Schutzer one of the first, the causality conditions in the S- matrix theory suggested (later named after the two). He was next to Marvin Goldberger also one of the first looked at the dispersion relations.

Later he dealt among other things with cosmologies from Gödel type. In 1970 he developed with Bollini and Gambiaga an alternative to general relativity.

Tiomno was a member of the Brazilian Academy of Sciences and the Academy of Sciences in Sao Paulo and received the 1994 Ordem Nacional de Merito Cientifico. In 1957 he received the Moinho - Santista Prize.
