Roberto Peccei

Roberto Daniele Peccei (; January 6, 1942 – June 1, 2020) was a theoretical particle physicist whose principal interests lay in the area of electroweak interactions and in the interface between particle physics and physical cosmology. He was most known for formulating the Peccei–Quinn theory (with Helen Quinn), which attempts to resolve the strong CP problem in particle physics.

Peccei was a vice chancellor for research at the University of California, Los Angeles between 2000 and 2010.

Early life and education The son of Aurelio Peccei (founder of the Club of Rome), Roberto Peccei was born in 1942 in Torino, Italy. He completed his secondary school in Argentina, and came to the United States in 1958 to pursue his university studies in physics. He obtained a B.S. from MIT in 1962, and M.S. from New York University (NYU) in 1964 and a Ph.D. from the MIT Center for Theoretical Physics in 1969.

Career After a brief period of postdoctoral work at the University of Washington, he joined the faculty of Stanford University in 1971, where (with Helen Quinn) he originated Peccei–Quinn theory, still the most famous proposed solution to the strong CP problem. In 1978, he returned to Europe as a staff member of the Max Planck Institute in Munich, Germany. He joined the Deutsches Elektronen-Synchrotron (DESY) Laboratory in Hamburg, Germany, as the head of the Theoretical Group in 1984. He returned to the United States in 1989, joining the faculty of the Department of Physics at UCLA. Soon thereafter, he became chair of the department, a position he held until becoming dean of the division of physical sciences of the College of Letters and Sciences in 1993. Recipient of the American Physical Society’s 2013 J. J. Sakurai Prize for Theoretical Particle Physics
