ATLAS Single Top-Quark t-Channel Cross-Sections at 13 TeV

3.2 fb^-1 of proton-proton collision data at 13 TeV from the LHC in 2015 was used to measure t-channel single-top-quark and top-antiquark production cross-sections. The measurement, conducted by the ATLAS collaboration, analyzed events with one charged lepton, missing transverse momentum, and two high-transverse-momentum jets, one of which was b-tagged. Cross-sections were determined using a binned maximum-likelihood fit to a neural network discriminant distribution.

Use Cases

• Validate and constrain theoretical models of electroweak top-quark production based on measured cross-sections.
• Train machine learning models for event classification using the neural network discriminant mentioned in the description.
• Analyze b-tagging efficiency and jet kinematics in lepton+jets top-quark events.
• Compare single top-quark and top-antiquark production rates to study charge asymmetry.

Strengths

• Data from the ATLAS detector at CERN's LHC, a major high-energy physics facility.
• Analysis uses a neural network for discriminant fitting, suggesting a sophisticated event selection.
• Measurement is based on 3.2 fb^-1 of collision data at a specific center-of-mass energy of 13 TeV.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
