TL;DR
This paper discusses how top quark decays, particularly ttbar production, are utilized to calibrate key detector components at the LHC, including trigger systems, jet energy scales, and b-tagging.
Contribution
It introduces a method of using top quark events for detector commissioning and calibration at the LHC.
Findings
Top quark decays effectively calibrate detector components.
ttbar production provides a high cross-section source for calibration.
Calibration improves detector performance and measurement accuracy.
Abstract
The large ttbar production cross-section at the LHC suggests the use of top quark decays to calibrate several critical parts of the detectors, such as the trigger system, the jet energy scale and b-tagging.
