ATLAS Search for Top Squarks in 13 TeV Proton Collisions

Results from a search for supersymmetric top squarks using 3.2 fb⁻¹ of proton-proton collision data at a center-of-mass energy of 13 TeV, recorded by the ATLAS detector at CERN's LHC in 2015. The analysis targets gluino-mediated and direct stop pair production, with final states containing one isolated lepton, jets, and missing transverse momentum. No significant excess over Standard Model predictions was observed, leading to exclusion limits on gluino and stop masses.

Use Cases

• Testing supersymmetry models based on the reported exclusion limits for gluino and stop masses.
• Reinterpreting results for other new physics models, such as vector-like top quarks, as mentioned in the description.
• Validating background estimation techniques for searches involving isolated leptons, jets, and missing transverse momentum.
• Comparing experimental sensitivity between gluino-mediated and direct stop pair production scenarios.

Strengths

• Data originates from the ATLAS detector at CERN, a major high-energy physics experiment.
• Analysis uses a defined integrated luminosity of 3.2 fb⁻¹ of proton-proton collision data.
• Sets specific exclusion limits, such as a gluino mass up to 1460 GeV and a stop mass region from 745 to 780 GeV.

Limitations

• Row count, column definitions, and file formats are unknown, limiting suitability assessment.
• Data is from a specific 2015 run; results may be superseded by newer analyses.
• Column-level documentation is absent; field semantics must be inferred from the paper.
