Summary
A new preprint extends single-minus amplitudes from gluons to gravitons in quantum gravity, demonstrating that certain graviton interactions previously thought to vanish can actually occur under specific kinematic conditions. The research shows that single-minus graviton tree amplitudes are nonzero, challenging long-held assumptions in the field. The work was conducted by researchers from multiple institutions including the Institute for Advanced Study, Vanderbilt University, and OpenAI, with GPT-5.2 Pro assisting in derivation and verification.
