David Kosower

David A. Kosower (* around 1960) is an American theoretical particle physicist. He is a professor at the Research Center Commissariat à l'énergie atomique et aux énergies alternatives (CEA) in Saclay .

Kosower studied physics at Harvard University with a bachelor's degree in 1982 and a doctorate in 1986 with Howard Georgi (Light composite fermions). He was a post-doctoral student at Columbia University until 1988, at Fermilab from 1988 to 1991 and at CERN in 1992/93 . From 1993 he is at the CEA in Saclay.

He was visiting professor at the University of Zurich and at the Weizmann Institute and held courses at the Kavli Institute for Theoretical Physics and the Galileo Galilei Institute in Florence.

With Zvi Bern and others, from the 1990s onwards, he developed new methods for the calculation of Feynman diagrams in quantum chromodynamics and other Yang Mills theories ( generalized unitarity methods, among others), which meet the requirements of the next to leading order calculations by the large Hadron Collider became more topical in the 2000s and also provided new insights into the divergences in the fault series in supergravity .

2014 he was awarded with Zvi Bern and Lance J. Dixon the Sakurai Prize for pioneering studies on perturbative calculation of scattering amplitudes to a deeper understanding of quantum field theory and powerful new tools for calculating processes of quantum chromodynamics led .

In 2009 he received an Advanced Research Grant from the European Research Council .
