Feynman integrals are where fundamental laws of nature become quantitative predictions—and where the demands of physics reveal unexpected mathematical elegance. From precision tests at colliders to the nonlinear dynamics of gravitational interactions, loop integrals directly connect our most fundamental theories to physical observables.

 

This lecture series is designed to offer young scientists a welcoming, step-by-step gateway into the subject. Through lectures and discussions, participants will explore the fundamentals of loop integrals, parametric representations, integration-by-parts (IBP) reduction, and the differential-equation method, as well as polylogarithms and related special functions. The aim is to equip participants with both practical tools for evaluating Feynman integrals and a deeper understanding of the mathematical structures underlying precision physics.

 

Prerequisites: A strong passion for science, together with a deep curiosity and enthusiasm for exploring frontier problems in fundamental physics. You should have a basic background in calculus and algebra, together with basic programming skills.

Organizer: Zhengwen Liu
