Advancements in Pixel Upgrades for High-Precision Sensors in Particle Physics

The Pixel Upgrade group, comprising experts like Giovanni C., Jacques C., and others, is advancing the development of edgeless planar sensors aimed at the Phase-II Inner Detector. Our research focuses on reducing dead areas to approximately 100 μm and involves extensive design and simulation using TCAD. Initial testing in our clean room has commenced, with exciting new projects underway, including electronics and mechanics R&D for improved sensor performance. We aim to enhance tracking precision for Higgs self-coupling analysis through collaborative efforts and innovative approaches.
