ATLAS Experiment: Jet Mass and Substructure in 7 TeV Proton-Proton Collisions

2010 data from the ATLAS experiment at CERN's LHC, with an integrated luminosity of 35 pb-1, measuring the structure of inclusive jets from proton-proton collisions at a centre-of-mass energy of 7 TeV. The measurements are corrected for detector effects and use two jet algorithms, anti-kT and Cambridge-Aachen, to present distributions of jet mass, kT splitting scales, and N-subjettiness variables. The data was authored by G. Aad and published on the paperswithcode platform.

Use Cases

• Training ML models for jet tagging and classification based on mass and substructure variables.
• Benchmarking theoretical QCD predictions against experimental measurements of jet mass distributions.
• Comparing the performance of different jet algorithms (anti-kT vs. Cambridge-Aachen) for substructure analysis.
• Studying event characteristics and pile-up mitigation techniques in high-energy collisions.

Strengths

• Data is from a major high-energy physics experiment (ATLAS at CERN LHC), ensuring authoritative provenance.
• Measurements are corrected for detector efficiency and resolution, indicating processed, analysis-ready data.
• Specific experimental parameters are provided: centre-of-mass energy of 7 TeV and integrated luminosity of 35 pb-1.

Limitations

• Column-level documentation is absent; field semantics must be inferred from the paper after download.
• Row count and file format are unknown, which may limit suitability assessment for large-scale ML.
• Last update date is unknown; freshness unverified.
