René Turlay

René Turlay (* 1932 ; † November 29, 2002 ) was a French physicist who dealt with experimental particle physics and is known as one of the participants in the experiment to discover the CP violation .

Turlay was from 1957 at the nuclear research center of the CEA in Saclay, where he studied pi-meson production in nucleon-nucleon scattering at 2.3 GeV at the Saturne Synchrotron. That was also the subject of his dissertation. As a post-doctoral student he was at Princeton University from 1962 . From 1962 to 1964 he took part in the experiment by James Cronin , Val Fitch and James Christenson at Brookhaven National Laboratory , in which the CP violation was discovered in the decay of neutral K mesons . Cronin and Fitch received the Nobel Prize for this in 1980.

Turlay continued his experiments on the K-Meson system in Saclay and at CERN. From 1973 he was involved in the CHDS collaboration at the Super Proton Synchrotron on the interaction of high-energy neutrinos. He worked with Jack Steinberger . He was also involved in the LEP's ALEPH detector (whose roots were in the CHDS). He was later chairman of the LEP Committee.

He also later worked with Fitch (via mesons with Charm at Fermilab ) and Cronin and Bruce Winstein (direct measurement of CP violation).

From 1978 to 1979 he headed a study group for the planned Hera Ring at DESY .

In 1984 he became head of the elementary particle physics department in Saclay and headed its expansion to the DAPNIA department, which also included astrophysics and nuclear physics. After his retirement in Saclay, he was involved in the NA48 collaboration at CERN, where, among other things, the direct CP violation was observed (1999).

In 1981 he received the Holweck Prize . He was a Knight of the Legion of Honor.
