Understand

In the modern on-shell approach, the perturbative S-matrix is constructed iteratively using on-shell building blocks with manifest unitarity.

As only gauge invariant quantities enter in the intermediate steps, the notion of gauge anomaly is absent.
In this letter, we rephrase the anomaly cancellation conditions in a purely on-shell language.
We demonstrate that while the unitarity-methods automatically lead to a unitary S-matrix, the rational terms that are required to enforce locality, invariably give rise to inconsistent factorization channels in chiral theories.
