AI Agents Can Already Autonomously Perform Experimental High Energy Physics
arXiv · 2603.20179
The Takeaway
Researchers found that modern AI models can independently manage the entire scientific process—from reading previous research to analyzing complex data from particle accelerators like the Large Hadron Collider. This marks a shift from AI as a simple processing tool to an autonomous 'colleague' capable of conducting its own high-level scientific discoveries.
From the abstract
Large language model-based AI agents are now able to autonomously execute substantial portions of a high energy physics (HEP) analysis pipeline with minimal expert-curated input. Given access to a HEP dataset, an execution framework, and a corpus of prior experimental literature, we find that Claude Code succeeds in automating all stages of a typical analysis: event selection, background estimation, uncertainty quantification, statistical inference, and paper drafting. We argue that the experime
