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 $139\,\mathrm{fb^{-1}}$. [...]

Combination of searches for non-resonant and resonant Higgs boson pair production in the $b\bar{b}\gamma\gamma$, $b\bar{b}\tau^{+}\tau^{-}$ and $b\bar{b}b\bar{b}$ decay channels using $pp$ collisions at $\sqrt{s}$ = 13 TeV with the ATLAS detector
This note presents a combination of searches for Higgs boson pair production using 126-139 $\mathrm{fb}^{-1}$ of proton-proton collision data recorded with the ATLAS detector at a center-of-mass energy of $\sqrt{s}=$ 13 TeV at the LHC. [...]

Calibration of flavour tagging algorithms in ATLAS on $t\bar{t}$ and $Z$+jets final states / Pereira Sanchez, Laura (Stockholm University (SE)) ; ATLAS Collaboration
The correct identification of $b$-initiated jets ($b$-jets) against $c$-initiated ($c$-jets), hadronic tau-initiated (tau-jets) and $u$-, $d$-, $s$-initiated jets (light-jets) is primordial for ATLAS Collaboration searches and precision measurements e.g. [...]

The Control System of the New Small Wheel Electronics for the ATLAS experiment / Tzanis, Polyneikis (National Technical Univ. of Athens (GR))
The present ATLAS Small Wheel Muon detector will be replaced with a New Small Wheel(NSW) detector in order to cope up with the future LHC runs of high luminosity.One crucial part of the integration procedure concerns the validation of the electronics for a system with more than 2.1 M electronic channels.
