CERN-LHC data provides a measurement of the W boson production cross-section in association with b-jets from proton-proton collisions at a centre-of-mass energy of 7 TeV. The results are based on data corresponding to an integrated luminosity of 4.6 fb⁻¹ collected by the ATLAS detector. Cross-sections are presented as a function of jet multiplicity and the transverse momentum of the leading b-jet for both muon and electron decay modes of the W boson.
Use Cases
- Benchmarking next-to-leading order QCD calculations based on the reported fiducial cross-section measurement.
- Analyzing jet multiplicity distributions in W+b-jet events based on the described cross-section presentation.
- Studying the transverse momentum spectrum of leading b-jets associated with W boson production.
- Comparing production cross-sections between the muon and electron decay channels of the W boson.
Strengths
- Data is based on a specific integrated luminosity of 4.6 fb⁻¹, indicating a substantial data sample.
- Cross-sections are corrected for all known detector effects, suggesting a processed, analysis-ready state.
- Results are presented with both statistical (±0.5 pb) and systematic (±1.4 pb) uncertainties quantified.
- Measurement is performed within a defined kinematic range (jet pT > 25 GeV, rapidity within ±2.1).
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment for certain modeling tasks.
- Last update date is unknown; freshness unverified.
Provenance
