Anthropic 称 Claude 在 Claude Science 中完成九圈散射振幅计算
New on the Science Blog: Yes, Claude can do Nine Loops.
Anthropic 在科学博客中称，Claude 在 Claude Science 中仅凭一条描述九圈问题的提示词，基本无监督运行数天，用 Dixon 及其同事的方法完成了平面 N=4 超对称杨-米尔斯模型中的九圈散射振幅计算，总成本为几千美元。此前该模型的纪录是八圈，由 SLAC 的 Lance Dixon 及合作者保持；Dixon 独立验证了这次结果，物理学家兼科学作者 von Hippel 为博客撰写了这一经历。

New on the Science Blog: Yes, Claude can do Nine Loops.
Theoretical physicists predict how particles behave using formulas called scattering amplitudes. These are notoriously hard to compute, so researchers work with layers of increasingly fine corrections called “loops”—each added loop makes the answer more precise but takes exponentially more computation. Most calculations stop at two or three loops. Eight loops was the previous record in a simplified model physicists use as a testing ground (planar N=4 super-Yang-Mills), set by SLAC's Lance Dixon and collaborators.
Last month, physicist and science writer @4gravitons issued a challenge: could an AI push past eight loops in this model, using only the compute budget an academic could reasonably access?
Given a single prompt describing the nine-loop problem, Claude ran largely unsupervised for days in Claude Science and solved it using methods developed by Dixon and his colleagues, at a total cost of a few thousand dollars. Dixon independently verified the result, and von Hippel wrote about the experience for our blog.
