  • On the spanning cuts consistency problem in the IBP reductions of Feynman integrals hep-ph · 2026-06-01 · unverdicted · none · ref 14 · internal anchor

    Inconsistency in spanning cuts for IBP reductions arises because cuts can make hidden terms in IBP relations finite via pinch singularities that cancel vanishing parameters, linked to hidden linear relations between propagators, for which an algorithm is provided.
