The Center for Particle Theory was established in 1968 with funds provided by the National Sciences Foundation. Harold Hanson, Tom Griffy and Alfred Schild recruited Yuval Ne'eman to come part-time to the Department of Physics. A center was established which included Ne'eman and Arno Bohm who had come from Syracuse University. Bohm urged the department to recruit George Sudarshan, also at Syracuse. Sudarshan agreed to come and requested an appointment for Austin M. Gleeson, a theorist in his group and who also was running George's program at Syracuse. Sudarshan and Gleeson came in 1969. Sudarshan brought his AEC funding and post-docs with him. The National Sciences foundation provided a number of Faculty Associates for the center. These included: Mike Simmons, Robert Yaes, Ron Parsons, John Campbell, Michael Grundzik, Arnold Lopez-Cepero and Robert Beck Clark.
Following the decision to build the Superconducting Super Collider (SSC) in Texas, the department decided to hire some high energy experimentalist. Austin Gleeson was the University's SSC Committee Representative.
1967: Yuval Ne’eman joined the University of Texas faculty and held a concurrent appointment with Tel Aviv University.
1968: Center for Particle Theory established at University of Texas at Austin.
1968: Yuval Ne'eman appointed Director. Ne'eman had completed his PhD at Imperial College London under the supervision of Abdus Salam. In his thesis, he discovered the SU(3) symmetry theory of the hadrons. Due to other commitments, the thesis was completed in 1961 at the age 36. In 1963, he joined Gell-Mann at Caltech as a postdoctoral fellow. The discovery of the O-particle at Brookhaven National Laboratory in 1964 established SU(3) symmetry and Ne'eman had many job offers. He was best known for the Eightfold Way classification of elementary particles, developed simultaneously with Murray Gell-Mann in the early 1960s. He died in 2006.
In 1968, Arno Bohm joined the Center. He was currently a research fellow at Syracuse University. Bohm has earned his Diploma and Doctorate from the Technical University in Berlin in 1966 with Günther Ludwig. From 1966–1968 he was at Syracuse University. Previous experience included research at Technical University at Karlsruhe, Germany and University of Marburg. Bohm's research interest includes: Group theoretical methods in particle physics, the idea of the spectrum generating group, relativistic spectrum generating group and relativistic collective models. Also research on the quantum geometric phase and foundations and applications in molecule physics. Work on the rigged Hilbert space formulation of quantum mechanics, with applications to decay and Golden Rule, time evolution semigroup, and irreversible quantum theory. Bohm retired 201?.
In 1969, George Sudashan joined the Center. He was a professor of physics at Syracuse University. He was the originator (with Robert Marshak) of the V-A theory of the weak force (later propagated by Richard Feynman and Murray Gell-Mann), which eventually paved the way for the electroweak theory. He also made important contributions to quantum optics.
In 1969, Austin M. Gleeson joined the Center. Gleeson had attended Drexel Universithy for his undergraduate studies. He earned a BS in 1960. He did his graduate work at the University of Pennsylvania, receiving his PhD in 1965. Following his graduation, Gleeson joined the faculty of Syracuse University. Austin Gleeson was the chief adminstrator for the UT Center for Particle Physics for a number years. He later became department chair. His research interest included field theory of strong interactions, the physics of superdense matter and high energy acoustic sources. He retired in 2020.
In 1969, Sudarshan appointed Jagdish Mehra as special research associate in the center; he remained in that position until 1973. Mehra, born in India and educated in Switzerland, PhD in 1963, had been at Purdue University, U. of Maasachursetts and at IBM in Chicago. His interest was history of science, in particular quantum theory. In 1970, Helmut Rechenberg joined the center. He had done a diploma with Walther Gerlach and a PhD with Werner Heisenberg. Rechenberg and Sudarshan worked on dispersion relations. While at Texas, Rechenberg began a collaboration with Mehra. The two worked closely with Sudarshan and Ilya Prigogine. They later published a six-volume work, "The Historical Development of Quantum Theory". In 1973, Professor Prigogine appointed Mehra as Professor at the Solvay Institute in Brussels where he remained until 1988. Mehra served as UNESCO-Sir Julian Huxley Distinguished Professor of History of Science in Paris, and Trieste, Italy (1989-93), and was the Citadel Distinguished Professor of Physics in Charleston, South Carolina (1993-96). He also was Regent's Professor in the University of California at Irvine. He was professor of science and humanities at the University of Houston. Mehra died in Houston in 2008. Rechenberg, after leaving Texas in 1972, held positions in Geneva, Brussels, Krakow, Northwestern University and Kyoto. He became the curator of the Heisenberg Archives at the Max Planck Institute. He wrote many biographies of scientists, including Gerlach and Heisenberg. He died on November 10, 2016 in Munich, Germany.
In 1971, Charles Chiu, a research fellow at Cal Tech joined the center. His interest was soft hadron physics, in particular, soft collision phenomena using multiple scattering models. Chiu continued in the center until his retirement. More details of his career can be found at Charles Chiu.
In 1973, Duane A. Dicus, from the University of Rochester, joined the center. Dicus had received his PhD from UCLA in 1968. His interests included, weak and electromagnetic interactions, chiral and guage field theories and Regge poles. Dicus collaborated with a post-doc in the center, Nilendra G. Deshpande. Deshpande became a Professor of Physics at the University of Oregon. Dicus served as Director for a number of years. He remained in the center until his retirement in 2020.
In 1973, Nilendra G. Deshpande joined the Center as a visiting Associate Professor. He had a very productive year collaborating with Duane Dicus.
They looked at extending flavor group to include the charm quark in SU(4)framework. This was before the discovery of charm. They wrote a couple of very influential papers on the MIT bag model in collaboration with Ken Johnson from MIT. Despande also worked with George Sudarshan on a standard like model, but without explicit Higgs boson. After a long calculation, the theory turned out not to be renormalizable at two loops. Deshpande comments, "Duane put in all the hard work. We did get a preprint on this work." Deshpande was a classmate of Austin Gleeson from Penn. They played tennis every evening. After the year ar Texas Deshpande left for Poland on a NSF grant that George Sudarshan and Arno Bohm had. After six months, he went to Gothenberg for six months to work with Professor Jan Nielson, who was a student of George's. He next joined the physics faculty at the University of Oregon in 1975. He served as Head of Physics from 1992 to 1998 and Associate Dean in charge of Sciences from 1998 to 2001. He is now Professor Emeritus.
