Titre Infrared information: an accelerated quark paradigm
Résumé Some observations about the interplay of quantum information theoretic issues and the infrared problem in gauge field theories are reviewed. A simple model of a quantum amplitude computation for accelerated heavy quarks in N=4 supersymmetric Yang-Mills theory is formulated and used to study the infrared divergences which would arise at the leading order of weak coupling perturbation theory. It is argued that the answer to some fundamental questions about the realization of global colour symmetry depend crucially on how the infrared problem is resolved. An extrapolation of some aspects of the discussion to strong coupling and large $N$ using AdS/CFT holography are explored.
