Topic: Scattering amplitudes at the intersection of QFT, strings and mathematics

Speaker: Prof. Song He

Abstract: Recently, powerful computational tools and remarkable new structures for perturbative scattering amplitudes in QFT have been discovered. Apart from playing the central role in high-energy particle physics, these developments have important implications for formal QFT, string theory and mathematics. I will review some recent progress, focusing on new geometric structures underlying scattering of particles and strings, which may hint at a theory at infinity for S-matrices.
