 METNet: A combined $p^{\text{miss}}_{\text{T}}$ working point using a neural network with the ATLAS detector In order to suppress pile-up effects and improve the resolution, ATLAS employs a suite of working points for missing transverse momentum ($p_{\text{T}}^{\text{miss}}$) reconstruction, and each is optimal for different event topologies and different beam conditions.

 Expected tracking and related performance with the updated ATLAS Inner Tracker layout at the High-Luminosity LHC As part of the ATLAS Phase-II upgrade, the current Inner Detector of the experiment will be replaced with a new all-silicon Inner Tracker (ITk) designed to face the challenging environment associated with the high number of collisions per bunch crossing.

 Expected performance of the ATLAS detector under different High-Luminosity LHC conditions A major upgrade of the LHC is planned to be completed by 2027, resulting in the so-called High-Luminosity LHC (HL-LHC) operating at a target luminosity of $5\times10^{34}~\mathrm{cm}^{-2}\mathrm{s}^{-1}$, with a possibility to reach an ultimate peak luminosity of up to $7.5\times10^{34}~\mathrm{cm}^{-2}\mathrm{s}^{-1}$.

 Combined effective field theory interpretation of differential cross-sections measurements of WW, WZ, 4l, and Z-plus-two-jets production using ATLAS data Coefficients of the Standard Model Effective Field Theory are constrained in a combined interpretation of differential cross-section measurements of $WW$ and $WZ$ production in leptonic final states, four-lepton production, and the production of a leptonically decaying $Z$ boson in vector-boson-fusion topologies.
