AI Model Identifies New Nonzero Formula for Single-Minus Gluon Amplitudes
Researchers from multiple institutions, with assistance from OpenAI’s GPT-5.2, report a result showing that tree-level scattering amplitudes for configurations with one negative-helicity gluon and the rest positive are nonzero in a constrained momentum alignment they call the half-collinear regime. The work, set out in a preprint titled "Single-min…
