Tullio Regge

from Wikipedia, the free encyclopedia

Tullio Eugenio Regge (born July 11, 1931 in Turin , † October 23, 2014 in Orbassano ) was an Italian physicist who mainly worked in theoretical elementary particle physics .

Life

After a youth in the post-war years in which he was in danger of slipping into a criminal environment, he graduated in physics from the University of Turin in 1952 . From 1954 to 1956 he continued his studies at the University of Rochester in New York , received his doctorate there and went to Werner Heisenberg at the Max Planck Institute for Physics in Munich in 1958/1959 . In 1960 he developed the Regge calculus , a discrete version of the general theory of relativity . In this area he also worked with John Archibald Wheeler since the 1950s (investigation of the Schwarzschild singularity 1957). From 1961 he was professor for theoretical physics in Turin. In the 1960s he worked mainly in Princeton and at the Institute for Advanced Study there , of which he was a member from 1964. In 1979 he finally returned to Italy. He became a professor at the Turin Polytechnic .

After 1979 Regge was a visiting scientist at CERN several times .

Regge was also politically active. From 1989 to 1994 he was a member of the European Parliament . With his friend Edoardo Amaldi , he was a member of the Italian Society for the Study of Paranormal Phenomena ( CICAP ). He wrote regularly in Italian newspapers, e.g. B. Le Scienze , the Italian edition of Scientific American .

He was a member of the Accademia Nazionale dei Lincei and, since 1975, of the Accademia Nazionale delle Scienze . In 1982 he was elected a member of the American Philosophical Society . In 1964 he received the Dannie Heineman Prize for Mathematical Physics , the Francesco Somaini Prize for Physics in 1967 , the Albert Einstein Award in 1979 , the Dirac Medal (ICTP) in 1996 and the Pomeranschuk Prize in 2001 . In 1970 he was invited speaker at the International Congress of Mathematicians in Nice (subject: Feynman integrals and S-Matrix ).

Best known is his work on the analytic S-matrix theory of strong interactions . When considering the angular momentum space expanded into the complex , it was possible to establish relationships between the masses and angular momenta for the hadron resonances (which corresponded to Regge poles ); they could be arranged on Regge trajectories ( Regge theory ). The idea of ​​the program was to construct the S-matrix from symmetry arguments and analytical continuation. In the 1960s it was seen as a hopeful alternative to conventional quantum field theory . It experienced a boom similar to string theory in the 1980s. In addition, Regge investigated the mathematical structure of the Feynman integrals . In the 1990s he dealt again with the theory of gravity ( quantum gravity , group theoretical approach).
