John Iliopoulos

John Iliopoulos ( Jean Iliopoulos, Ioannis Iliopoulos actually, Greek Ιωάννης Ηλιόπουλος, born 1940 in Kalamata, Greece) is a Greek particle physicist.

Iliopoulos studied at the Technical University of Athens ( completion 1962) and then in Paris, where in 1963 his DEA degree made ​​in 1965 was awarded a degree in physics ( thesis de 3.Cycle ) and 1968 and to the theory group in Orsay Claude Bouchiat Philippe Meyer received his doctorate. 1966 to 1968 he was at CERN and then 1969 to 1971, a Research Associate at Harvard. After that, he was a scientist of the CNRS. He is currently Director of the Institute for Particle Physics at the École Normale Supérieure in Paris.

Sheldon Lee Glashow, Iliopoulos, and Luciano Maiani supplied with the GIM mechanism in 1970 as a first indication of the existence of a fourth quark, later known as the charm quark. With Claude Bouchiat and Philippe Meyer 1972 he gave conditions for the disappearance of anomalies in the electroweak interaction, which provided further evidence for the existence of three color degrees of freedom at that time.

In 2002, Iliopoulos was the first winner of the Aristeio Prize, which was launched to honor the Greeks who have made significant contributions to their field of science. In 1987 he was awarded the Sakurai Prize for Theoretical Particle Physics together with Maiani. In 1990 he became a corresponding member and in 2002 a full member of the Académie des sciences. 2007 saw Iliopoulos and Maiani the Dirac Medal. In 1978 Iliopoulos the Paul Langevin Prize, in 2013 the Prix des trois physiciens. In 2011 he was awarded the High Energy and Particle Physics Prize of the EPS.
