Berkeley Center For Theoretical Physics
The Berkeley Center for Theoretical Physics (BCTP) is a research center for theoretical particle physics, cosmology, string theory and quantum gravity at the University of California at Berkeley. About The BCTP houses theoretical physics research at Berkeley and has close links to Lawrence Berkeley National Laboratory (LBNL). It is located in Old LeConte Hall on the Berkeley campus. Though the BCTP itself was founded at the turn of the 21st century, Berkeley has a rich history in the field of theoretical particle physics, with prominent former physicists including Manhattan project director Robert Oppenheimer; Nobel Laureates Steven Weinberg, Sheldon Glashow, and David Gross; Breakthrough Prize winners John Schwarz, Joseph Polchinski, and Nima Arkani-Hamed; Sakurai Prize winners Mary Gaillard, Leonard Susskind, and Lisa Randall; as well as Dirac Medal winners Bruno Zumino and Stanley Mandelstam Stanley Mandelstam (; 12 December 1928 – 23 June 2016) was a South African th ...

Particle Physics
Particle physics or high energy physics is the study of fundamental particles and forces that constitute matter and radiation. The fundamental particles in the universe are classified in the Standard Model as fermions (matter particles) and bosons (force-carrying particles). There are three generations of fermions, but ordinary matter is made only from the first fermion generation. The first generation consists of up and down quarks which form protons and neutrons, and electrons and electron neutrinos. The three fundamental interactions known to be mediated by bosons are electromagnetism, the weak interaction, and the strong interaction. Quarks cannot exist on their own but form hadrons. Hadrons that contain an odd number of quarks are called baryons and those that contain an even number are called mesons. Two baryons, the proton and the neutron, make up most of the mass of ordinary matter. Mesons are unstable and the longest-lived last for only a few hundredths of ...

LeConte Hall
LeConte Hall is the former name of a building on the campus of the University of California, Berkeley, which is home to the physics department. LeConte Hall was one of the largest physics buildings in the world at the time it was opened in 1924, and was also the site of the first atom collider, built by Ernest O. Lawrence in 1931. The building was named in honor of the brothers Joseph and John LeConte, professors of Physics and Geology, who were respectively the first and third presidents of the university. Their last name was removed from the building in 2020 due to their white supremacist views. As of 2021, the university has not decided on a permanent name. History In 1924, the university opened LeConte Hall in order to accommodate an enlarged physics department, and to support the hiring of new, talented faculty. One of the newly hired faculty was Ernest Lawrence, who joined the department in 1928. Lawrence, together with students M. S. Livingston and David Sloan built an 11- ...

Stanley Mandelstam
Stanley Mandelstam (; 12 December 1928 – 23 June 2016) was a South African theoretical physicist. He introduced the relativistically invariant Mandelstam variables into particle physics in 1958 as a convenient coordinate system for formulating his double dispersion relations. The double dispersion relations were a central tool in the bootstrap program which sought to formulate a consistent theory of infinitely many particle types of increasing spin. Early life Mandelstam was born in Johannesburg, South Africa to a Jewish family.William D. Rubinstein, Michael Jolles, Hilary L. Rubinstein, ''The Palgrave Dictionary of Anglo-Jewish History'', Palgrave Macmillan (2011), p. 110 Work Mandelstam, along with Tullio Regge, did the initial development of the Regge theory of strong interaction phenomenology. He reinterpreted the analytic growth rate of the scattering amplitude as a function of the cosine of the scattering angle as the power law for the falloff of scattering amplitudes a ...

Bruno Zumino
Bruno Zumino (28 April 1923 − 21 June 2014) was an Italian theoretical physicist and faculty member at the University of California, Berkeley. He obtained his DSc degree from the University of Rome in 1945. He was renowned for his rigorous proof of the CPT theorem with Gerhart Lüders; his pioneering systematization of effective chiral Lagrangians; the discoveries, with Julius Wess, of the Wess–Zumino model, the first four-dimensional supersymmetric quantum field theory with Bose-Fermi degeneracy, and initiator of the field of supersymmetric radiative restrictions; a concise formulation of supergravity; and for his deciphering of structured flavor-chiral anomalies, codified in the Wess–Zumino–Witten model of conformal field theory.

John Henry Schwarz
John Henry Schwarz (; born November 22, 1941) is an American theoretical physicist. Along with Yoichiro Nambu, Holger Bech Nielsen, Joël Scherk, Gabriele Veneziano, Michael Green, and Leonard Susskind, he is regarded as one of the founders of string theory. Early life and education He studied mathematics at Harvard College (A.B., 1962) and theoretical physics at the University of California at Berkeley (Ph.D., 1966), where his graduate advisor was Geoffrey Chew. For several years he was one of the very few physicists who pursued string theory as a viable theory of quantum gravity. His work with Michael Green on anomaly cancellation in Type I string theories led to the so-called "first superstring revolution" of 1984, which greatly contributed to moving string theory into the mainstream of research in theoretical physics. Schwarz was an assistant professor at Princeton University from 1966 to 1972. He then moved to the California Institute of Technology (Caltech), where he ...
