ATLAS Detector: Search for Squarks and Gluinos in 8 TeV Proton-Proton Collisions

CERN's Large Hadron Collider recorded 20.3 fb^{-1} of proton-proton collision data at a center-of-mass energy of 8 TeV in 2012. The ATLAS experiment used this data to search for supersymmetric particles like squarks and gluinos in final states with high-pT jets and missing transverse momentum. The analysis, led by G. Aad, sets exclusion limits on particle masses for various supersymmetry-breaking models.

Use Cases

• Training anomaly detection models based on high-pT jets and missing transverse momentum signatures.
• Benchmarking classification algorithms for distinguishing supersymmetry signals from Standard Model backgrounds.
• Validating statistical analysis methods for setting exclusion limits at the 95% confidence level.
• Testing parameter inference techniques in simplified supersymmetry-breaking models like mSUGRA/CMSSM.

Strengths

• Data originates from a major international experiment (ATLAS) at the Large Hadron Collider.
• Analysis is based on a specific, high integrated luminosity of 20.3 fb^{-1}.
• Results provide concrete exclusion limits, such as a gluino mass limit of 1330 GeV for a specific simplified model.

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.
