John Ellis (physicist)

Jonathan R. Ellis CBE ( born July 1, 1946 in London ) is a British theoretical physicist who deals with elementary particle physics.

Life

Ellis grew up in Potters Bar and studied at Cambridge mathematics and physics ( and some classical Greek history ). During his PhD at Cambridge, he was at CERN. After his graduation he went to SLAC and Caltech. Since 1973 he has worked at CERN, where he spent six years headed the Theory Department, among others. In the 1970s he worked on quantum chromodynamics, CP violation and the Higgs boson. Since the 1980s, string theory came (including with Dimitri Nanopoulos development of the "flipped SU ( 5) " GOOD from the heterotic string ) added, GUTs, neutrino physics, supersymmetry, cosmological applications, quantum gravity. He worked on studies for physics at LEP and LHC and is working on studies for the feasibility of the LHC 's successor with ( CLIC, an electron-positron collider ). He is also responsible for the connection to the CERN non-Member States.

In Ellis, the designation of " penguin diagrams " ( eg Feynman diagrams of CP violation ) goes back and the " Theory of Everything " ( ToE ) ( in Nature, 1986). By his own admission, he was also involved in the invention of the term " Grand Unified Theories ".

Ellis is married and has two children.
