Calibration tools

Overview of available tools and outstanding tasks: A&S 2020-02-04.

Tracking efficiency

• TrackCalib: create custom tracking efficiency tables for muons
• Electron tracking efficiency: create custom tracking efficiency tables for electrons
• tracking asymmetries: Package for determining the K-Pi+ detection asymmetry for any physics analysis (including reweighting tools).
• Proton detection asymmetry: evaluations of the proton detection asymmetry with calibration samples.

Momentum scale

• Momentum scaling: correction of the momentum scale for real data.

Charged PID efficiency

• PIDCalib: PID efficiencies from real data using calibration samples.
• PIDGen & PIDCorr: Resample/transform PID variables on MC according to real calibration samples.
• Electron PID efficiency: PID efficiencies for electrons from calibration samples using fit & count.

Electron/Neutral reconstruction/PID efficiency

• Overview of available neutral ID variables
• CALO objects tools and documentation
• & efficiencies (study from Run 1)
• Current (as of 2021) developments on the IsNotH and IsPhoton calibrations

Trigger efficiency

• L0 efficiencies: from calibration samples.

Herschel usage & calibration

• Herschel in analysis: instructions on how to use Herschel info in your analysis.

Performance measurements & plots

• Detector performance papers
• LHCb-FIGURE documents - all public plots, including performance.
• Tracking & Alignment performance plots - gradually being replaced by LHCb-FIGURE docs.
• PID performance plots - also being replaced by LHCb-FIGUREs.
• CALO Objects conference plots - likewise.
• Archive plots
