OpenAI and academic collaborators report that a gluon scattering case long treated as zero at tree level can become nonzero in a specific half-collinear momentum regime, challenging the standard generic-momenta argument and introducing a new calculable result. The team says GPT‑5.2 Pro first conjectured their final formula (Eq. 39) after simplifying hand-derived base cases up to n=6, and an internal scaffolded GPT‑5.2 later produced a formal proof over roughly 12 hours. The preprint is posted on arXiv, submitted for publication, and the authors say related extensions to graviton amplitudes are already underway.
