Anthropic：Claude 在简化模型中完成九圈散射振幅计算
Anthropic 科学博客称，理论物理中的散射振幅计算随圈数增加呈指数级变难，此前简化模型（平面 N=4 超杨-米尔斯）的纪录为八圈。物理学家兼科普作者 4gravitons 发起挑战后，Claude 在 Claude Science 中依据单一提示、基本无监督运行数天，采用 Dixon 等人发展的方法完成九圈计算，总成本数千美元，Lance Dixon 独立验证了结果。该结果限于特定简化模型，不代表通用物理发现能力。
AI推荐理由 Anthropic 官方 Science Blog 介绍：物理学家 4gravitons 提出挑战，Claude 在 Claude Science 中依据单一提示、基本无监督运行数天，在平面 N=4 超杨-米尔斯简化模型中将散射振幅计算推进到九圈，超过此前八圈记录，总成本数千美元，并由原记录作者 Lance Dixon 独立验证。属具体、可追溯的研究案例，涉及 AI 用于理论物理计算与长时自主运行；但结果限于特定简化模型，尚不能外推为通用科学发现能力。

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.
