Search for Higgs Boson Pair Production in the $b\bar{b}\tau^+\tau^-$ Final State with the ATLAS Experiment at the LHC / Deutsch, Christopher
A search for Higgs boson pair (HH) production in final states with two $b$ quarks and two $\tau$ leptons using 139 fb$^{-1}$ of proton-proton collision data at a centre-of-mass energy of 13 TeV recorded by the ATLAS detector at the Large Hadron Collider (LHC) is presented [...]
