Abstract

The Compact Muon Solenoid (CMS) detector at CERN is one of two general-purpose experiments at the Large Hadron Collider (LHC). The contributions of Swiss institutions and funding agencies to the construction of the CMS detector have been highly significant, most notably in the electromagnetic calorimeter (ECAL) and the pixel vertex (PIX) detector sub-components. These investments span more than 20 years of intense detector R&D and hardware development as well as engineering and construction. During this period, Swiss scientists have become world leaders in the respective detector technologies. Since 2010, the LHC has provided high-quality, high-statistics data sets using proton-proton collisions at the highest center-of-mass energies of 7, 8, and 13 TeV ever reached by a man-made particle accelerator, creating opportunities for important discoveries at the high energy frontier. Commensurate with the large investments made by the funding agencies and CMS institutions of Switzerland, Swiss scientists from ETH Zurich, the Paul Scherrer Institute, and the University of Zurich, led by the principal investigators signing this proposal, are playing highly visible roles in the physics exploitation of these datasets acquired with CMS, most notably in the recent discovery of a Higgs boson particle, but also in searches for physics beyond the standard model, and precision standard model measurements. The funding for academic personnel afforded by the respective SNF base grants of the PIs has proven to be crucial for these successes. For the continued exploitation of the CMS experiment, infrastructure investments, and technical support for high-performance computing as well as engineering support for highly efficient detector operations are indispensable. Furthermore, the physics potential of the LHC will allow for a rich particle physics program for at least the next 20 years to come. In order to ensure the best physics exploitation of the ever-improving LHC capabilities in a correspondingly harsh and unprecedented radiation environment, the LHC detectors need to be upgraded, in a first (Phase I) step through 2020 and in a second step around 2027 (Phase II) as part of the High Luminosity operations of the LHC (HL-LHC). The LHC Experiments Committee (LHCC), Resources Review Board (RRB), and Upgrade Cost Group (UCG) have reviewed and approved the recently released Phase-II CMS Technical Design Reports (TDRs). This joint proposal of the three Swiss CMS institutions presents a well-balanced portfolio of subprojects dedicated to these aforementioned tasks for the period 2021-2025. In particular, subproject A deals with the demands on high performance (TIER3) computing infrastructure needed to perform cutting-edge data analysis and the necessity for moderate upgrades to cope with the ever-increasingly large datasets. Subproject B is dedicated to the maintenance and continuous improvement of the ECAL detector control system that is indispensable for high-efficiency data taking. Subproject C presents the work on the Phase-II upgrade for the ECAL readout electronics. Subprojects D and E detail the work on the Phase-II upgrade for the pixel detector in mechanics and integration, and in prototyping and production of pixel modules. Subproject F deals with the research and development of detectors for CMS for the long-term HL-LHC. Such activities are very timely since the development of such new technologies needs a persistent research effort over many years.
