Particle physics or high-energy physics is the study of fundamental particles and forces that constitute matter and radiation. The field also studies combinations of elementary particles up to the scale of protons and neutrons, while the study of combination of protons and neutrons is called nuclear physics.
SLAC National Accelerator Laboratory, originally named the Stanford Linear Accelerator Center, is a federally funded research and development center in Menlo Park, California, United States. Founded in 1962, the laboratory is now sponsored by the United States Department of Energy and administrated by Stanford University. It is the site of the Stanford Linear Accelerator, a 3.2 kilometer (2-mile) linear accelerator constructed in 1966 that could accelerate electrons to energies of 50 GeV.
James Watson Cronin was an American particle physicist.
The BaBar experiment, or simply BaBar, is an international collaboration of more than 500 physicists and engineers studying the subatomic world at energies of approximately ten times the rest mass of a proton (~10 GeV). Its design was motivated by the investigation of charge-parity violation. BaBar is located at the SLAC National Accelerator Laboratory, which is operated by Stanford University for the Department of Energy in California.
Eva Silverstein is an American theoretical physicist, cosmologist, and string theorist. She is a professor of physics at Stanford University and director of the Modern Inflationary Cosmology collaboration within the Simons Foundation Origins of the Universe initiative.
Joel R. Primack is an American physicist. He is a professor of physics and astrophysics at the University of California, Santa Cruz, and is a member of the Santa Cruz Institute for Particle Physics.
Helen Rhoda Arnold Quinn is an Australian-born particle physicist and educator who has made major contributions to both fields. Her contributions to theoretical physics include the Peccei–Quinn theory which implies a corresponding symmetry of nature(related to matter-antimatter symmetry and the possible source of the dark matter that pervades the universe) and contributions to the search for a unified theory for the three types of particle interactions. As Chair of the Board on Science Education of the National Academy of Sciences, Quinn led the effort that produced A Framework for K-12 Science Education: Practices, Crosscutting Concepts, and Core Ideas—the basis for the Next Generation Science Standards adopted by many states. Her honours include the Dirac Medal of the International Center for Theoretical Physics, the Oskar Klein Medal from the Royal Swedish Academy of Sciences, appointment as an Honorary Officer of the Order of Australia, the J. J. Sakurai Prize for Theoretical Particle Physics from the American Physical Society, the Karl Taylor Compton Medal for Leadership in Physics from the American Institute of Physics, the 2018 Benjamin Franklin Medal in Physics from the Franklin Institute, and the 2023 Harvey Prize from Technion -- Israel Institute of Technology.
Ann Elizabeth Nelson was a particle physicist and professor of physics in the Particle Theory Group at the University of Washington from 1994 until her death. Nelson received a Guggenheim Fellowship in 2004, and she was elected to the American Academy of Arts and Sciences in 2011 and the National Academy of Sciences in 2012. She was a recipient of the 2018 J. J. Sakurai Prize for Theoretical Particle Physics, presented annually by the American Physical Society and considered one of the most prestigious prizes in physics.
Gerson Goldhaber was a German-born American particle physicist and astrophysicist. He was one of the discoverers of the J/ψ meson which confirmed the existence of the charm quark. He worked at Lawrence Berkeley National Laboratory with the Supernova Cosmology Project, and was a professor of physics at the University of California, Berkeley as well as a professor at Berkeley's graduate school in astrophysics.
Lev Borisovich Okun was a Soviet theoretical physicist. He is known for his contributions to particle physics and quantum chromodynamics. He coined the term hadron.
Bruce Winstein was an experimental physicist and cosmologist noted for his early work in elementary particle physics, particularly work toward demonstrating a serious asymmetry between particles and their anti-particles. Later in his career, he worked in experimental cosmology, measuring polarization in the microwave background radiation whose properties date back to the early universe.
James E. Brau is an American physicist at the University of Oregon (UO) who conducts research on elementary particles and fields. He founded the Oregon experimental high energy physics group in 1988 and served as director of the UO Center for High Energy Physics from 1997 to 2016. Prior to joining the Oregon faculty, he served in the Air Force and held positions at the Stanford Linear Accelerator Center and the University of Tennessee. He is a fellow of both the American Physical Society and also the American Association for the Advancement of Science. In 2006 he was appointed the Philip H. Knight Professor of Natural Science, an endowed professorship.
Charles Young Prescott is an American particle physicist.
