4. Current and future FCC-ee vertex detector layouts and their performance

Armin Ilg (University of Zürich)

This contribution presents the layouts and performance of the CLD and IDEA/ALLEGRO vertex detectors. Starting from this, more advanced layouts are explored:

• Ultra-light IDEA vertex detector concept using wafer-scale monolithic active pixel sensors (MAPS) stitched in two dimensions
• FCC-SEED vertex detector concept using MAPS stitched in one dimension
• A first look at a potential...

10. The Belle II-VXD running experience and the mechanical integration of the DMAPS VTX-upgrade in the new I.R. design.

Stefano Bettarini (Istituto Nazionale di Fisica Nucleare)

Since 2019, the Belle II experiment at the SuperKEKB B-factory in Tsukuba, Japan has been collecting data from asymmetric-energy e−e+ collisions at the Υ(4S) resonance, holding the world luminosity record of 5.1×10^34 cm^-2 s^−1, reached in 2024.
The Vertex Detector (VXD) provides a vertex resolution of approximately 10 µm, allowing highly precise tracking and vertex reconstruction, essential...

7. Towards realistic digitization of silicon tracking detectors for the FCC

Jessy Daniel (IP2I)

A detailed digitizer for the silicon-pixel tracking detector of the CLD concept at the FCC is under development within the Key4HEP software framework. The digitizer models the detector response starting from the interaction of charged particles with the silicon sensors, including charge deposition, charge transport in electric and magnetic fields, thermal diffusion, and the response of the...
