Collider Physics Today and Tomorrow: Searches for new physics with ATLAS and building the smart detectors of the future

The ATLAS experimenters at CERN's Large Hadron Collider are exploring our femtoscopic universe by searching for exotic new particles. Discovering these minuscule motes of matter would have a tremendous impact on our understanding of the universe as a whole: potentially unraveling the secrets of dark matter or the source of the Higgs boson mass. We will dive into the latest results of searches with top quark signatures and long-lived particles. We'll also look forward to future detectors, discussing both the ATLAS detector upgrade for the High-Luminosity LHC and prospects for future colliders. Work on intelligent sensors for the Allegro detector concept at a proposed future circular collider at CERN will be presented.
