On the spanning cuts consistency problem in the IBP reductions of Feynman integrals
Zihao Wu, Yingxuan Xu
The spanning cuts method is a powerful approach to reduce the cost of IBP reduction while computing Feynman integrals. However, its usage is limited due to the so-called consistenc…

Performing integration-by-parts reductions using NeatIBP 1.1 + Kira
Zihao Wu, Janko Böhm, Rourou Ma +3
We introduce a new version v1.1 of NeatIBP. In this new version, a Kira interface is included. It allows the user to reduce the integration-by-parts (IBP) identity systems generate…
