Pierre Fayet

from Wikipedia, the free encyclopedia

Pierre Fayet (born December 4, 1949 ) is a French theoretical physicist who was a pioneer in the field of supersymmetry in the 1970s .

career

Fayet studied at the École normal supérieure in Paris (ENS). From 1977 to 1979 he was at the California Institute of Technology (Caltech) and then at CERN . He is Research Director of the Center national de la recherche scientifique (CNRS) at the Laboratory for Theoretical Physics (LPTENS) of the ENS. He is also a professor at the École polytechnique .

A mechanism of spontaneous breaking of supersymmetry is named after him and John Iliopoulos . This was the first mechanism to spontaneously break the symmetry of supersymmetry, and he developed another a little later (and independently of Lochlainn O'Raifeartaigh ).

In 1976 Fayet showed the need to introduce new supersymmetric particles and introduced a new quantum number, R-symmetry (where particles with even R-parity correspond to the normal particles of the Standard Model and the superpartners have odd R-parity). With this he laid the foundations for the minimal supersymmetric model . In 1976 he gave the first examples of gauge theories with extended N = 2 supersymmetry.

In 1997 he became a corresponding member of the Académie des sciences , and in 2013 a full member.

In 2018, Fayet was one of the 200 signatories of an appeal in the newspaper Le Monde , in which it was warned of drastic consequences, such as the extinction of human species, unless a rapid rethinking of problem areas such as climate change and the extinction of species and wider planetary limits occurs.
