Speaker: Professor Henriette Elvang (UM Physics)Quantum field theory is the mathematical language of particle physics. It models the interactions between elementary particles in Nature and the forces through which they interact. The agreement between the theoretical predictions of quantum field theory and experimental results is remarkable, and currently new results are anticipated with excitement from the Large Hadron Collider. Professor Elvang illustrates the ideas of quantum field theory, why we need it, and how it is used in particle physics. Feynman diagrams will be explained, and she also outlines some novel approaches that reveal a surprising and enticing mathematical richness in particle scattering processes.
