Combination of searches for resonant Higgs boson pair production using $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector
A combination of searches for resonant Higgs boson pair production is presented, using up to 139 fb$^{-1}$ of $pp$ collision data at $\sqrt{s}=13$ TeV recorded with the ATLAS detector at the LHC. [...]
