Run 3 of the LHC will resume in April 2023. The luminosity in 2023 may exceed 2x10^34/cm^2/s. Arizona contributions to the upgraded ATLAS detector include 2M channels of front-end electronics for the Micromegas detectors on the New Small Wheel (NSW) and FPGA firmware used by the new Liquid Argon Digital Trigger. My group is finishing two analyses using the Run 2 dataset: a search for one long-lived particle decaying in the Muon Spectrometer and an optimization of the four-top quark production cross section and its limits on the Two-Higgs-Doublet Model and Higgs oblique parameter. We hope to ramp up our participation in Run3 physics this year including NSW performance studies.
