Factorization in Graviton Scattering and the "Natural" Value of the g-factor

TL;DR

This paper reviews the factorization property of graviton scattering amplitudes, emphasizing that it holds only when the gyromagnetic ratio g_S is set to the natural value of 2, regardless of particle spin.

Contribution

It demonstrates that graviton scattering factorization is valid exclusively at the natural g-factor value of 2 across all spins.

Findings

Factorization holds only at g_S=2

Validity of factorization is independent of particle spin

Supports the natural g-factor value as fundamental in graviton interactions

Abstract

The factorization property of graviton scattering amplitudes is reviewed and show to be valid only if the "natural" value of the gyromagnetic ratio $g_S=2$ is employed -- independent of spin.
