Maurice Jacob, 1998

Maurice René Michel Jacob (born March 28, 1933 in Lyon ; † May 2, 2007 ) was a French theoretical physicist who dealt with elementary particle physics.

Jacob studied physics from 1953 at the École normal supérieure and was then at the French nuclear research center in Saclay . During a stay at Brookhaven National Laboratory in 1959, he and Gian-Carlo Wick developed the helicity amplitude formalism for scattering of elementary particles. In 1961 he was the issue before the University of Paris with Francis Perrin (and Wick) PhD , was ( "formal theory of collisions and helicity eigenstates") then as a post-doc at Caltech and then from 1961 to 1967 again in Saclay. From 1967 he was at CERN (from 1972 as a permanent member), where he stayed until his retirement in 1998. From 1982 to 1988 he was head of the CERN theory group and in the 1990s was responsible for the relationship between CERN and its member states. In addition, he was also visiting fellowships at SLAC , Yale University and Fermilab . Jacob died of a heart attack after a long illness.

Jacob was particularly concerned with the phenomenology of the strong interaction in high-energy scattering processes, for example including hadron generation and the observed scaling behavior, jet generation (with Ron Horgan), prediction of processes with high transversal impulses in proton-proton scattering . He was an early proponent of studying quark-gluon plasma in heavy ion collisions. In the 1980s he also dealt with accelerator physics (beam instabilities, radiation), partly with Tai Tsun Wu . Jacob always kept in close contact with the experiment and in the 1970s was an important "integrator" for the physicists at the Intersecting Storage Rings (ISR) of CERN and organized important conferences to prepare the accelerators LEP and LHC of CERN and supported the construction of the Proton -Antiproton Collider by Carlo Rubbia for the 1980s.

In 1967 he received the CNRS silver medal . In 1985 he was President of the French Physical Society and from 1991 to 1993 of the European Physical Society . In 1993 he became a Fellow of the American Physical Society . He was Associate Editor of Physics Letters B and Physics Reports. He was a Knight of the Legion of Honor , a corresponding member of the French Academy of Sciences and a member of the Swedish Academy of Sciences and the Academia Europaea . Jacob was also a scientific advisor to ESA .

Jacob was married and had four children, including the film actress Irène Jacob .
