CERN-LHC. The dataset contains results from a search for direct pair production of the top squark, the scalar partner to the top quark, using 20.1 fb^{-1} of proton-proton collision data at a center-of-mass energy of 8 TeV. The search was conducted by the ATLAS detector and targets fully-hadronic final states with four or more jets and large missing transverse momentum. No significant excess over the Standard Model background was observed, and exclusion limits are reported for top squark and neutralino masses under different decay branching fractions.
Use Cases
- Train statistical models to set exclusion limits based on integrated luminosity and event counts.
- Analyze the relationship between top squark mass, neutralino mass, and branching fractions for different decay channels.
- Benchmark new supersymmetry search strategies against the reported fully-hadronic final state selection.
- Validate background prediction methods for events with large missing transverse momentum and multiple jets.
Strengths
- Integrated luminosity of 20.1 fb^{-1} provides a substantial data sample for analysis.
- Exclusion limits are reported with specific mass ranges, such as 270-645 GeV for a 100% branching fraction to stop -> t chi1^0.
- Analysis considers multiple decay scenarios, including stop -> t chi1^0 and stop -> b chi1^{+/-}.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
