Claude computes nine-loop scattering amplitude, verified by SLAC's Lance Dixon for ~$1–2K
EricBuess · x · 2026-09-26
Eric Buess highlights a guest post by @4gravitons for Anthropic: Claude computed a nine-loop scattering amplitude in a physics test-bed model, at roughly $1–2K per method, with SLAC physicist Lance Dixon verifying the result. Song He's group, assisted by GPT-6, obtained a concurrent result. A landmark AI-for-Science case of frontier LLMs reaching expert-verifiable accuracy in theoretical physics.
