Seminar

Title: Gluon scattering: Feynman, Spinor, and CHY tree amplitudes

Speaker: Prof. Chi-Sing Lam (蓝志成) (McGill University, Canada)

Time: 10:00AM, May 23rd (Monday)

Place: Theoretical Physics Division，319

Abstract: In this talk, the speaker compares the usual Feynman diagram construction and the CHY construction of the amplitude. It turns out that although these two must give the same result, their approaches are completely opposite, their results are also grouped differently.
