Search for Higgs boson pair production in the $b\bar{b}WW^\ast$ decay mode at $\sqrt{s}=13$ TeV with the ATLAS detector
A search for Higgs boson pair production in the $b\bar{b}WW^\ast$ decay mode is performed in the $b\bar{b}l\nu qq$ final state using 36.1 fb$^{-1}$ of proton-proton collision data at a centre-of-mass energy of 13 TeV recorded with the ATLAS detector at the Large Hadron Collider. [...]

Search for the production of a long-lived neutral particle decaying within the ATLAS hadronic calorimeter in association with a $Z$ boson from $pp$ collisions at $\sqrt{s} = 13$ TeV / ATLAS Collaboration
This Letter presents a search for the production of a long-lived neutral particle decaying within the ATLAS hadronic calorimeter, in association with a Standard Model $Z$ boson produced via an intermediate scalar boson, where $Z \rightarrow l^+ l^-$ ($l=e,\mu$). [...]
