The Canadian Association of Physicists (CAP) is pleased to announce that the 2012 CAP Herzberg Medal is awarded to Freddy Cachazo, Perimeter Institute, in recognition of for deep new insights into the structure of quantum field theory, and the development of elegant mathematical techniques to simplify the analysis of high-energy particle scattering experiments. announcement

Dr. Freddy Cachazo is a theoretical physicist who has made outstanding contributions to the field of particle physics, many of which are widely characterized as breakthroughs. With collaborators, Cachazo has creatively drawn upon a variety of elegant mathematical ideas, including twistor theory, Grassmanians and algebraic geometry, to develop entirely new methods of calculating scattering processes in gauge theories and gravity. Beyond providing deep new insights into the structure of quantum field theory, these new methods have had a major impact on high-energy physics. In particular, Cachazo’s techniques have become essential in state-of-the-art calculations done to interpret the new data coming from experiments at the Large Hadron Collider at CERN, as well as the Tevatron at Fermilab. His work has already been incorporated into a textbook on quantum field theory, and his work has continued to open up entirely new research directions now being investigated all over the world. Cachazo’s contributions to quantum field theory range from applications of geometric engineering (in string theory) to understanding mysterious dualities relating theories in different dimensions to improved techniques to compute scattering amplitudes in Quantum Chromodynamics (and its generalizations). In a research career spanning less than a decade, Cachazo’s 41 papers have attracted well over 4,000 citations, attesting to the rapid, far-reaching impact of his new insights. The principles underlying Cachazo’s research are profound. Besides being of immediate utility to huge accelerator experiments, Cachazo’s works will have enduring and far-reaching impact in the search for a simpler, unified description of nature’s physical laws. nominator citation
