Prospects on SM and Higgs Physics at the HL-LHC

After a very concise summary of the Run1 results on the Higgs sector, the most important milestones in the physics programme of LHC and its luminosity upgrade HL-LHC are briefly discussed. A summary of the main Higgs boson production modes and decay final states at the HL-LHC is reported, with emphasis on the measurement of couplings to elementary bosons and fermions, and on the search for rare decay modes. Examples of interpretation of the Higgs couplings in the context of the 2HDM model, and of direct BSM Higgs bosons are briefly illustrated. Finally, the VBS process is also discussed.
