Direct Proof of the TreeLevel Scattering Amplitude Recursion Relation in YangMills Theory
Abstract
Recently, by using the known structure of oneloop scattering amplitudes for gluons in YangMills theory, a recursion relation for treelevel scattering amplitudes has been deduced. Here, we give a short and direct proof of this recursion relation based on properties of treelevel amplitudes only.
