Strings and bootstraps. The Veneziano model


Feynman and QCD
Murray Gell-Mann Scientist

Feynman resisted believing in QCD for quite a few years. He thought that somehow the gluon propagator would be fundamentally one over K to the fourth, so that—for small k--so that one would get fundamentally, not as a result of radiative corrections but fundamentally, a confining potential. It's not really possible and I don't why he believed that but he… that's what he said for a long time. Finally at a meeting in Irvine in the winter of, what was it? ’75, ’76 I think, he finally caved in and said, all this stuff I've been doing is just an approximation to QCD. But it took quite a while.

New York-born physicist Murray Gell-Mann (1929-2019) was known for his creation of the eightfold way, an ordering system for subatomic particles, comparable to the periodic table. His discovery of the omega-minus particle filled a gap in the system, brought the theory wide acceptance and led to Gell-Mann's winning the Nobel Prize in Physics in 1969.

Listeners: Geoffrey West

Geoffrey West is a Staff Member, Fellow, and Program Manager for High Energy Physics at Los Alamos National Laboratory. He is also a member of The Santa Fe Institute. He is a native of England and was educated at Cambridge University (B.A. 1961). He received his Ph.D. from Stanford University in 1966 followed by post-doctoral appointments at Cornell and Harvard Universities. He returned to Stanford as a faculty member in 1970. He left to build and lead the Theoretical High Energy Physics Group at Los Alamos. He has numerous scientific publications including the editing of three books. His primary interest has been in fundamental questions in Physics, especially those concerning the elementary particles and their interactions. His long-term fascination in general scaling phenomena grew out of his work on scaling in quantum chromodynamics and the unification of all forces of nature. In 1996 this evolved into the highly productive collaboration with James Brown and Brian Enquist on the origin of allometric scaling laws in biology and the development of realistic quantitative models that analyse the influence of size on the structural and functional design of organisms.
