The five-twist identity for Feynman periods
Published 5 May 2025 in hep-th, math-ph, and math.MP | (2505.02578v1)
Abstract: We prove a new identity for Feynman periods that acts on five-vertex cuts of completed primitive Feynman graphs. It is shown that in $\phi4$ theory this identity is independent from existing identities which are the twist, the Fourier identity and the Fourier split.
