Description
Several proposals for future high-energy lepton colliders are currently under study, including circular (FCC-ee, CEPC) and linear (CLIC, LCF) options. The physics goals and experimental conditions at these 'Higgs Factories' pose challenging demands on the performance of the detector systems. For the silicon-based vertex and tracking layers, a single-plane spatial resolution of a few microns is needed, combined with very thin sensors (<100 microns). Moreover, hit-time tagging with a few nanosecond resolution is required to reject beam-induced background events for some of the collider options. An even better track-timing precision well below 100 ps opens up the possibility of particle identification by time-of-flight measurements.
To address these stringent detector requirements, a broad R&D program on new silicon-sensor technologies is being pursued within various collaborative frameworks.
This contribution introduces the Lepton-Collider detector requirements and gives an overview of the R&D program for silicon-based vertex and tracking detectors.
