Future physics potential of the CMS phase-II detector

To extend the LHC physics program, it is foreseen to operate the LHC in the future with an unprecedented high luminosity. To maintain the experiments physics potential in such harsh environment, the detector will need to be upgraded. At the same time the detector acceptance will be extended and new features such as a L1 track trigger will be implemented.Simulation studies evaluated the performance of the new, proposed detector components in comparison to the present detector with the expected aging after 1000/fb. The impact of the expected phase-II performance on representative physics channels is studied. The sensitivity to find new physics beyond the SM is significantly improved and will allow to extend the SUSY reach, search for dark matter and exotic long-lived signatures. Precision Higgs and standard model measurements will gain substantially due to the improved performance.
