Title: Looking for Unusual Ionization in High-Momentum Particles with the ATLAS Detector at the LHC
Abstract: What if we could measure the mass of every high momentum charged particle in the ATLAS detector? This talk details the tools in development to make that a reality for tracks associated with a large ionization energy loss (dE/dx). I will place particular emphasis on a new dE/dx measurement from gaseous drift tubes in the ATLAS Muon Spectrometer, born from a detailed understanding of detector hardware and readout electronics. I will present this measurement alongside other Muon-Spectrometer-based tools that aid us in the hunt for long-lived massive and/or di-charged particles, including dedicated reconstruction techniques. I will also discuss the progress of the New Small Wheel upgrade of the ATLAS Muon Spectrometer, and outline the commissioning of the MicroMegas detector trigger in view of the upcoming High-Luminosity LHC era.
