CERN-LHC ATLAS detector data measures two-particle correlations in relative azimuthal angle and pseudorapidity from sqrt(sNN) = 5.02 TeV proton-lead collisions recorded in September 2012. The analysis uses approximately 1 μb⁻¹ of data as a function of transverse momentum and transverse energy. The correlation function exhibits long-range near-side and away-side correlations consistent with a cos(2Δφ) modulation.
Use Cases
- Analyzing long-range particle correlations based on Δφ and Δη measurements
- Studying transverse energy dependence of correlation functions
- Modeling collective flow effects in proton-lead collisions
- Comparing near-side and away-side correlation magnitudes and shapes
- Testing theoretical predictions against experimental correlation data
Strengths
- Data from a specific experimental run in September 2012 at the LHC
- Analysis performed using approximately 1 μb⁻¹ of collision data
- Correlations measured as a function of transverse momentum (pT) and transverse energy
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
- Freshness unverified; last update date is unknown
