Description

In this talk I will discuss a new approach for generating integration-by-parts reductions of Feynman integrals. The approach makes use of ideas from modern unitarity and from algebraic geometry, which I will explain. I then demonstrate the power of the approach by performing fully analytically IBP reductions relevant for two-loop five-gluon scattering in QCD. I will also discuss Azurite, a publicly available code for providing bases of loop integrals.
