Special TDLI Seminar：Amplitudes as differential forms

by Dr Fei Teng (Uppsala University)

Friday 10 Jan 2020, 15:00 → 16:00 Asia/Shanghai

300-02 (Tsung-Dao Lee Institute (East wing of Pao Yue-Kong Library))

 

Abstract:

In this talk, I will first review some hidden structures of scattering amplitudes of gauge and gravity theories, especially the color-kinematics duality and double copy. I will then focus on realizing amplitude as the canonical form of certain positive geometry in the kinematic space, and show that the color-kinematics duality emerges naturally for both adjoint and fundamental representation particles.
