Projection of inclusive Search for Gluinos and Squarks at the HL-LHC ATLAS experiment

Supersymmetry is one of the most promising theories beyond the Standard Model and can solve the Hierarchy problem. For more sensitive searches of such New Physics and more precise measurements of Higgs couplings, the High Luminosity LHC (HL-LHC) experiment is planned to start in 2026, which it is expected to acquire 3000 fb$^{-1}$ of proton-proton collision data at a center-of-mass energy of 14 TeV. The ATLAS detector will be upgraded in order to handle higher luminosities. In 2018, groups in the ATLAS and CMS experiments study projections of main physics analysis channels toward the HL-LHC experiment. In particular, we focus on strongly-produced supersymmetric particles -- gluinos and squarks.
