Precise muon detection: novel technologies for the luminosity frontier — •Kerstin Hoepfner — RWTH Aachen, Phys. Inst. 3A, Aachen, Germany

Muons play an essential role in the discovery of new particles because of their potential to warrant a clean signature and low background. Outstanding examples from the past include the finding of the bottom quark as well as the tau lepton, and more recently the discovery of the Higgs boson. At present another type of signature is gaining importance: displaced muons as a probe for potential new BSM particles.

At the upcoming High-Luminosity LHC, muon detection as well as muon triggering face big challenges in terms of rate and precision. Consequently, modern muon systems evolve beyond being pure particle identification devices and rather turn into complex and high granularity trackers. High particle rates and densities also imply the requirement of increased radiation tolerance.

In anticipation of these challenges, new detection technologies were developed, largely based on micro-pattern gas detectors. These detectors provide a high spatial and time resolution. For the upcoming High-Luminosity LHC, the high-rate experiments ATLAS and CMS install large-scale systems of such detectors for muon detection. Their superior performance makes these detectors also good candidates for other applications in particle physics.
