物理学院何颂学术报告的通知（School of Physics Colloquium）

题目：散射振幅新进展报告人：何颂邀请人：杨李林时间：2023年11月2日（周四）15:30地点：紫金港校区海纳苑8幢215报告厅摘要：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.个人简介：何颂，中科院理论物理研究所研究员。长期研究量子场论、引力和弦论等高能理论方向，近年来主要研究散射振幅及其对粒子物理、引力和数学等方面的应用。代表性工作包括提出量子场论散射振幅的 Cachazo-何-袁形式，发现粒子和弦散射的几何起源，以及在场论高圈计算，规范场、引力和弦论对偶等方向的一系列工作。
