Cosmic Ray Muons Timing in the ATLAS Detector

TL;DR

This paper discusses how calorimeter timing in the ATLAS detector, using cosmic ray muons data, helps identify detector errors and improves searches for new physics like supersymmetry by reducing false signals.

Contribution

It presents the application of calorimeter timing for detector calibration and background suppression in high-energy physics experiments, with real and simulated cosmic muon data.

Findings

Calorimeter timing can uncover detector calibration errors.

Timing resolution aids in suppressing cosmic ray fake signals.

Results demonstrate improved search sensitivity for new physics.

Abstract

In this talk I discuss the use of calorimeter timing both for detector commissioning and in searches for new physics. In particular I present real and simulated cosmic ray muons data results for the ATLAS Tile Calorimeter system. The analysis shows that several detector errors such as imperfect calibrations can be uncovered. I also demonstrate the use of ATLAS Tile Calorimeters excellent timing resolution in suppressing cosmic ray fake missing transverse energy in searches for supersymmetry.
