The spectrum of Feynman-integral geometries at two loops
Piotr Bargiela, Hjalte Frellesvig, Robin Marzucca +4
We provide a complete classification of the Feynman-integral geometries at two-loop order in four-dimensional Quantum Field Theory with standard quadratic propagators. Concretely,…

On the finite basis of two-loop `t Hooft-Veltman Feynman integrals
Piotr Bargiela, Tong-Zhi Yang
In this work, we investigate the finite basis topologies of two-loop dimensionally regularized Feynman integrals in the `t Hooft-Veltman scheme in the Standard Model. We present a…

Explainable AI-assisted Optimization for Feynman Integral Reduction
Zhuo-Yang Song, Tong-Zhi Yang, Qing-Hong Cao +2
We present a novel approach to optimizing the reduction of Feynman integrals using integration-by-parts identities. By developing a priority function through the FunSearch algorith…
