Agentic Lagrangian Extraction from the Literature ML4SCI – HEPSIM5

Hundreds of BSM Lagrangians have been proposed in the literature, but translating them into validated FeynRules .fr model files is still a manual, time-consuming process. This project builds an agentic system inside the HEPTAPOD framework that automates this workflow. Given a BSM scenario description, the agent searches INSPIRE and arXiv, extracts Lagrangian terms into a typed schema, generates a syntactically correct .fr file using deterministic Jinja2 templates, and validates the output through HEPTAPOD’s FeynRulesToUFOTool and a downstream MadGraph smoke test. Every literature source, extraction decision, and validation outcome is recorded in an audit trail.
