Gabriele Veneziano (born 7 September 1942[1]), is an Italian theoretical physicist and one of the pioneers of string theory.[2][3] Has spent most of his scientific activities at CERN in Geneva, Switzerland. Since 2004 he holds the Chair of Elementary Particles, Gravitation and Cosmology at the Collège de France in Paris.[2]

Background[edit]

Gabriele Veneziano was born in Florence, Italy where he graduated (Italian Laurea) in Theoretical Physics under the direction of Professor Raoul Gatto. He pursued his doctoral studies at the Weizmann Institute of Science in Rehovot, Israel and obtained his Ph.D. in 1967 under the supervision of Hector Rubinstein. During his stay in Israel and his early years at MIT, he collaborated with Marco Ademollo (a professor in Florence) Miguel Virasoro.[2] and Sergio Fubini.

Between 1968 and 1972 he worked at MIT and CERN. In 1972 he became Amos de Shalit Professor of Physics at the Weizmann Institute of Science and in 1976 he accepted a position in the Theory Division at CERN in Geneva, Switzerland where he worked for more than 30 years and directed the Theory Division (between 1994 and 1997). He currently holds the chair of Elementary Particles, Gravitation and Cosmology at the College of France in Paris, France. At present (Fall 2012), he spends a semester at New York University as Global Distinguished Professor.

Research[edit]

Gabriele Veneziano first formulated the rudiments of string theory in 1968 when he discovered a string picture could describe the interaction of strongly interacting particles.[4][5][6] Veneziano discovered that the Euler Beta function, interpreted as a scattering amplitude, has many of the features needed to explain the physical properties of strongly interacting particles. This amplitude, known as the Veneziano amplitude, is interpreted as the scattering amplitude for four open string tachyons. In retrospect this work is now considered the founding of string theory although at the time it was not apparent the string picture would lead to a new theory of quantum gravity.

Veneziano's work led to intense research to try to explain the strong force by a field theory of strings about one fermi in length. The rise of quantum chromodynamics, a rival explanation of the strong force, led to a temporary loss of interest in string theories until the 1980s when interest was revived.

In 1991, he published a paper[7] that shows how an inflationary cosmological model can be obtained from string theory, thus opening the door to a description of pre-big bang scenarios.
