Quantum field theory forms the foundation of our understanding of elementary particle physics. It provides the theoreticalÃÂ background for the interpretation of data from collider experiments. While quantum field theory is an old subject, over the lastÃÂ decade new features have begun to emerge which reveal new ways to understand it. In particular an astonishing simplicityÃÂ has been found at the heart of the maximally supersymmetric gauge theory in four spacetime dimensions, a close cousin ofÃÂ Quantum Chromodynamics (QCD), which describes the strong interactions.
My research team will use the new methods I have been developing to construct explicit results for scattering amplitudesÃÂ and correlation functions. We will develop these results into general statements about the analytic behaviour of scatteringÃÂ amplitudes. The approach will be based on my recent work on new dualities between amplitudes and Wilson loops and onÃÂ new symmetries revealing an underlying integrable structure. This research will allow us to answer key foundationalÃÂ questions such as the origin of Regge behaviour of scattering amplitudes in the high energy limit, and the connection toÃÂ string theory in the limit of strong coupling. We will also pursue the connection to quantum groups and formulate the problemÃÂ of scattering amplitudes in this language. This provide a solid mathematical underpinning to the formulation of the scatteringÃÂ problem in quantum field theories and allow application of techniques from the field of integrable systems to gauge theories.ÃÂ An enormous effort goes into performing the calculations of scattering amplitudes needed to make precise predictions forÃÂ collider experiments. New techniques to handle such calculations are much needed. We will develop new tools, such as theÃÂ application of differential equation methods for loop integrals and analytic bootstrap methods for amplitudes. This researchÃÂ will allow us to greatly improve on existing efforts to calculate processes in QCD.
