Elucidating the quantum structure of electroweak interactions in physics
Ses premières années d'études se déroulent dans d'assez mauvaises conditions, la Seconde Guerre mondiale ayant entraîné une pénurie matérielle et humaine.Il passe sa thèse en 1960 au CERN puis une grande partie de sa carrière à l'université d'Utrecht avant d'émigrer aux États-Unis en 1980 où il travaille à l'université du Michigan.Born in Den Helder, the Netherlands in 1946, Gerard 't Hooft studied physics and mathematics at the University of Utrecht. D in theoretical physics in 1972, and is presently a professor at that same institution. Hooft's primary research interests focus on gauge theories in elementary particle physics; quantum gravity and black holes; and fundamental aspects of quantum physics. 't Hooft's contributions to science have been honored with many awards, including the 1999 Nobel Prize in Physics, with the citiation "for elucidating the quantum structure of electroweak interactions in physics." Dr. Working in relative isolation, Veltman developed innovative theoretical techniques and pursued a project that was eventually completed by his Ph D student G. Developing Veltman’s idiosyncratic methods, ‘t Hooft independently derived the Higgs mechanism - discovered by various physicists around 1964 - and the gauge symmetry structure of the electroweak theory of Weinberg and Salam. Veltman Nobel Prize in Physics 1999 together with Gerardus 't Hooft"for elucidating the quantum structure of electroweak interactions in physics". Veltman worked on the programme of renormalizing the massive Yang-Mills gauge field theories in a period when the majority of his colleagues believed such theories to be non-renormalizable.
By 1979, thanks to this development the Glashow-Weinberg-Salam electroweak theory plus quantum chromodynamics had been broadly accepted as the Standard Model of particle physics.
He did most of his work for his Nobel Prize as a graduate student but did not receive the prize until 30 years later.
