ATLAS LHC Data: Charged-Particle Multiplicities in Proton-Proton Collisions

~190 microbarn^-1 of data at 7 TeV, ~7 microbarn^-1 at 0.9 TeV, and ~0.1 microbarn^-1 at 2.36 GeV were collected by the ATLAS detector at CERN's LHC. The dataset presents distributions of charged particle multiplicity and its dependence on pseudorapidity and transverse momentum. It was authored by G. Aad and last corrected in May 2016.

Use Cases

• Modeling particle production in proton-proton collisions based on charged particle multiplicity data.
• Analyzing pseudorapidity distributions of charged particles for detector calibration studies.
• Studying transverse momentum dependencies in high-energy physics event generators.
• Validating theoretical predictions against experimental data from three different centre-of-mass energies.

Strengths

• Data collected at three distinct centre-of-mass energies: 0.9, 2.36, and 7 TeV.
• Includes distributions for key physics variables: charged particle multiplicity, pseudorapidity, and transverse momentum.
• A correction was applied to the data in May 2016, indicating a review process.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
