Development of Small-Pitch, Thin 3D Sensors for Pixel Detector Upgrades at HL-LHC
… dense pixel granularity (50×50 or 25×100 μm2), thinner active region (~100 μm), narrower columnar electrodes (~5μm diameter) with reduced inter-electrode spacing (~30 μm), and very slim edges (~100 μm) into the 3D pixel sensor design. This thesis includes the development of this new generation of …

Searching for long-lived particles Beyond the Standard Model with displaced vertex signatures using the ATLAS detector: Not all hopes for new physics die immediately
… particles that decay into hadrons in the ATLAS inner detector. This was the first such Run 2 search, placing the best limits in this lifetime range to date on R-parity violating supersymmetry models. The second analysis uses a similar strategy, but using missing transverse energy as the trigger. …
