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 Potter's bar and studied math and physics (and some classical Greek history) at Cambridge . He was already at CERN during his doctorate in Cambridge . After completing his doctorate, he went to SLAC and Caltech . He has been working at CERN since 1973, where he headed the theory department for six years. In the 1970s he dealt with quantum chromodynamics , CP violation and the Higgs boson . Since the 1980s, string theory (including with Dimitri Nanopoulos development of the "flipped SU (5)" - GUT from the heterotic string), GUTs , neutrino physics , supersymmetry , cosmological applications, and quantum gravity have been added. He worked on studies for physics at the LEP and LHC and works on studies for the feasibility of an LHC successor (CLIC, an electron-positron collider). He is also responsible for connecting CERN to non-member states.

The naming of the “ penguin diagrams ” (Feynman diagrams, e.g. for CP violation) and the “ Theory of Everything ” (ToE) (in Nature 1986) go back to Ellis . According to his own statement, he was also involved in the invention of the term " Grand Unified Theories ".

In 1976, together with Mary K. Gaillard and Graham Ross , he proposed the detection of gluons as bremsstrahlung in electron-positron annihilation and quark-antiquark generation, which should be presented as a three-jet event. In 1979 this was verified at DESY's Petra storage ring.

Ellis is married and has two children.
