摘要：Recently, powerful computational tools and remarkable new structures for perturbative scattering amplitudes in QFT have been discovered. Apart from playing a key role in high-energy particle physics, these developments have important implications for formal QFT, string theory and mathematics. I will review some recent progress, including a new formulation based on geometries for scattering of particles and strings, as well as all-loop amplitudes in theories such as supersymmetric Yang-Mills and Chern-Simons.
