ATLAS Top Quark Pair Differential Cross-Sections from 2.05 fb^-1 of 7 TeV pp Collisions

Relative differential cross sections for top quark pair production in proton-proton collisions at a center-of-mass energy of 7 TeV. The data comprises 2.05 inverse femtobarns recorded by the ATLAS detector at the Large Hadron Collider between March and August 2011. Measurements are derived as a function of the invariant mass, transverse momentum, and rapidity of the top quark pair system, with events selected in the lepton-plus-jets channel.

Use Cases

• Validate theoretical predictions for top quark pair production based on differential cross-section measurements.
• Analyze the kinematic properties of top quark pairs based on invariant mass, transverse momentum, and rapidity distributions.
• Study systematic uncertainties in high-energy physics measurements based on the reported 10-20% uncertainty range.
• Calibrate or inform Monte Carlo event generators for top quark production based on background-subtracted, detector-corrected data.

Strengths

• Data sample of 2.05 inverse femtobarns provides a substantial event count for statistical analysis.
• Measurements are corrected for detector effects and normalized, enhancing comparability to theory.
• Uncertainties are quantified, typically ranging between 10% and 20%, providing clarity on measurement precision.

Limitations

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