Measurement prospects of Higgs boson pair production in the $b\bar{b}\gamma\gamma$ final state with the ATLAS experiment at the HL-LHC
A prospect study for the search for non-resonant Higgs boson pair production in the $b\bar{b}\gamma\gamma$ decay channel is presented, assuming 3000 $\text{fb}^{-1}$ of $pp$ collisions at $\sqrt{s}=14$ TeV with the ATLAS detector at the High Luminosity LHC (HL-LHC). [...]

Dark matter summary plots for $s$-channel and 2HDM+$a$ models
This is an update of summary plots from the Exotics, SUSY, HDBS and Higgs working groups, via the CDM sub-group, for dark matter simplified models with $s$-channel Spin-1 and Spin-0 mediators, and a Two-Higgs-Doublet model with a pseudoscalar mediator (2HDM+$a$). [...]

Extrapolation of ATLAS sensitivity to $H\rightarrow b\bar{b}$ and $H\rightarrow c\bar{c}$ decays in $VH$ production at the HL-LHC
The expected sensitivity of the measurements of Higgs boson decays into $b\bar{b}$ and $c\bar{c}$ with the ATLAS detector at the HL-LHC is estimated by extrapolating the results obtained using a dataset of $\sqrt{s}=13\,\mathrm{TeV}$ $pp$ collisions corresponding to an integrated luminosity of $139\,\mathrm{fb^{-1}}$.
