Future ATLAS Higgs Studies

The High-Luminosity LHC will prove a challenging environment to work in, with for example $<{\mu_{PU}}>=200$ expected. It will however also provide great opportunities for advancing studies of the Higgs boson. The ATLAS detector will be upgraded, and Higgs prospects analyses have been performed to assess the reach of ATLAS Higgs studies in the HL-LHC era. These analyses are presented, as are Run-2 ATLAS di-Higgs analyses for comparison.
