Analysis Systems

The goal of the Analysis Systems focus area is to develop sustainable analysis tools to extend the physics reach of the HL-LHC experiments by creating greater functionality, reducing time-to-insight, lowering the barriers for smaller teams, and streamlining analysis preservation, reproducibility, and reuse.

Focus Area Strategies:

Establish declarative specifications for analysis tasks and workflows that will enable the technical development of analysis systems to be decoupled from the user- facing semantics of physics analysis.
Leverage and align with developments from industry and the broader scientific software community to enhance sustainability of the analysis systems.
Develop high-throughput, low-latency systems for analysis for HEP.
Integrate analysis capture and reuse as first class concepts and capabilities into the analysis systems.
