Topic: Feynman integrals from bottom up

Speaker: Prof. Lilin Yang

Coordinates: PCFT C1124, 16:00, Thursday, March 28

 

Abstract: Feynman integrals are basic building blocks of perturbative scattering amplitudes in quantum field theories. In this talk, I will introduce ongoing efforts towards building the analytic solutions of Feynman integrals from bottom up. In particular, I will discuss the construction of canonical bases from dlog integrands, and the determination of symbol letters from well-educated ansatzes. I will also briefly introduce the theoretical tools employed, including the structure of Baikov representations and the intersection theory of Feynman integrals.
