Richard Lewis Arnowitt (born May 3, 1928 in New York City - † June 12, 2014 ) was an American theoretical physicist.

Life

Arnowitt studied at Rensselaer Polytechnic Institute ( Master's degree in 1948) and received his doctorate in 1953 from Harvard University (“The hyperfine structure of hydrogen”). From 1954 to 1956 he was at the Institute for Advanced Study in Princeton . He later was a professor at Northeastern University in Boston . Most recently (2007) he was Distinguished Professor Emeritus at Texas A&M University in College Station in Texas.

Arnowitt became known through the Arnowitt-Deser-Misner (ADM) formulation of the equations of motion of general relativity (and, related to it, a new mass / energy definition - ADM mass - in this theory), which he collaborated with Stanley Deser and Charles W. Misner Developed in the late 1950s and early 1960s. He worked extensively with his colleague at Northeastern University , Pran Nath , e.g. B. in the 1960s about current algebras (Current algebras e.g. in chirally symmetrical models of the interaction of pions in the 1970s about one of the first supergravity theories and the U (1) problem in quantum chromodynamics . He dealt with the 1980s, in particular with experimental predictions of string theory , supergravity (Minimal Supergravity Model of GUT , with Pran Nath and Ali Chamseddine , mSugra for short, and signals for the discovery of dark matter and supersymmetry in the large particle accelerator experiments (such as LHC ).

Arnowitt was a Guggenheim Fellow in 1975/76 . In 1994 he and Deser and Misner received the Dannie Heineman Prize for Mathematical Physics .

The contribution of large masses of symmetry breaks on the Planck and GUT scales is prevented by the fact that this takes place in a "hidden sector" that only overlaps with the other fundamental interactions on the electroweak scale the gravitation interacts.
