Abstract

Abstract The CMS collaboration is currently preparing the upgrade of the tracking system for the High-Luminosity LHC operations (HL-LHC). The HL-LHC is scheduled to start in 2027 and it will bring the instantaneous luminosity up to 7.5 × 1034 cm−2 s−1, with an average of 200 interactions per beam crossing, and an integrated luminosity up to 4000 fb−1 over a decade. To operate efficiently in these challenging conditions, the new detector has to provide tracking information to the first level trigger stage and maintain good and efficient offline tracking. In this contribution, the layout of the new detector, the main technology choices together with highlights on the current status of the main detector components will be presented.
