EasyScan_HEP 2: LLM-agent parameter-scan workflows in high energy physics

Abstract

Abstract Large-language-model (LLM) agents are beginning to reshape the preparation and steering of computational workflows in high-energy physics phenomenology. To accommodate this change, we upgrade _ to make the construction of parameter-scan configuration files more accessible to LLM-agent assistance. _ exposes command-line and machine-readable interfaces for LLM-agent workflows, allowing an assistant to translate natural language requests into an explicit configuration that defines the scan method, external-program workflow, constraints, and outputs. The resulting configuration can be inspected through a local Web interface. The framework also supports LLM-agent-guided extension to new scan methods, as illustrated by the integration of , , and . In this way, _ adapts parameter-scan workflows to LLM-agent use while preserving reproducibility, transparency, and user control.
