Higgs Physics at HL-LHC

The large dataset of about $3~{\mathrm{ab}^{-1}}$ that will be collected by both the ATLAS and CMS experiments at the High Luminosity LHC (HL-LHC) will be used to measure Higgs boson properties in detail. Studies based on current analyses have been carried out to understand the expected precision and limitations of these measurements. The large dataset will also allow for better sensitivity to Higgs boson pair production processes and the Higgs boson self-coupling. This proceeding presents the prospects for the precise measurements of the Higgs boson properties and Higgs boson pair production with the ATLAS and CMS detectors at the HL-LHC.
