Sumário do Projecto

The Physics Program of the CMS experiment at the Large Hadron Collider (LHC) is aimed at answering fundamental questions in particle physics. The data collected by the LHC experiments since 2010 has yielded a vast quantity of physics results. The highlight has been the observation in 2012 of a Higgs boson with mass of 125 GeV by the ATLAS and CMS collaborations.The detailed study of the Higgs boson is a scientific imperative that must be pursued to a much higher level of statistical precision than is available today. Precision Higgs studies and the search for new physics provide a powerful demand for higher luminosity. The High-Luminosity LHC (HL-LHC) expected in 2029 will achieve peak and integrated luminosity well above those for which CMS was designed. The CMS detector requires upgrades to preserve the efficiency, resolution, and background rejection of the detector at these high luminosities.In the past two decades, LIP made important contributions to the construction and to the Phase-1 Upgrade of the CMS detector, as well as to the physics program of the experiment. LIP had a leading role in the design and construction of critical components of the CMS detector, namely the Data Acquisition System (DAQ) of the ECAL sub-detector and the CMS Trigger System. After the LHC start-up in 2010, LIP made major contributions to the CMS physics program, in particular the discovery of a Higgs boson. In the Phase-1 Upgrade, the LIP group has built and installed a new system of High-Speed Optical Links that interface the ECAL electronics to the trigger system. The LIP group also led the development of the new forward Precision Proton Spectrometer (PPS), which is taking physics data integrated in CMS since 2016.Following the signature by FCT of the Memorandum of Understanding of the Phase-2 Upgrade, the LIP group is deeply involved in the R&D and construction of the detector upgrade. The group participates in three projects of the Phase-2 Upgrade of the CMS detector, namely the construction of the MIP Timing Detector (MTD), the upgrade of the electronics of Electromagnetic Calorimeter (ECAL), and the construction of a new high-granularity sampling calorimeter in the endcaps (HGCAL). Additionally, in the past years, LIP took a leading role in the proposal for the upgrade of the PPS spectrometer for HL-LHC, that has been recently approved. This research program reflects a close match and synergies between the historical role and technological expertise of the LIP group in the calorimeters and in the trigger of the CMS experiment, the new opportunities offered by the Phase-2 Upgrade of the CMS Calorimeters, and the recognized world-wide leadership of Portuguese microelectronics companies in the domains relevant for the project.The addition of a new timing detector in front of the calorimeters allows measuring the time of charge particles with a precision of 30 ps, which is required to minimize the very large background of pileup collisions preserving the CMS physics potential at HL-LHC. The LIP group has full responsibility for the design and construction of the frontend readout system of the barrel part of the MTD, including the delivery of a highperformance Time-of-Flight (TOF) ASIC for time measurement. The present application aims at funding the Portuguese activities in the CMS Upgrade.
