Recent precision W/Z measurements at the LHC (all relevant DY measurements), including full Run 2 and HL-LHC prospects / Cipriani, Marco (CERN) /ALICE,ATLAS,CMS and LHCB Collaborations
Precision measurements of W and Z boson cross sections and other properties are a powerful tool to validate theoretical calculations of the standard model, and are also essential in searches for new physics phenomena. These bosons are copiously produced in proton-proton collisions at the LHC, which permits several measurements to be performed differentially in many kinematic variables, often with negligible statistical uncertainties.

Double Higgs production at the LHC / Portales, Louis (Ecole Polytechnique) /ATLAS and CMS Collaborations
An overview of the latest results on resonant and non-resonant Higgs boson pair production, using up to 140~fb$^{-1}$ of $\sqrt{s}=13$~TeV proton-proton collision data recorded during Run~2 of the LHC by the ATLAS and CMS Collaborations, is presented. A wide range of decay modes is covered, with one Higgs boson decaying to $b\bar{b}$, and the second to $b\bar{b}$, $W^{+}W^{-}$, $ZZ$, $\tau^{+}\tau^{-}$ or $\gamma\gamma$, as well as different topologies, with studies of both resolved and boosted signals and for both gluon-gluon and vector-boson fusion production modes.

Top quark production in association with a vector boson at the LHC / Knolle, Joscha (Gent U.) /ATLAS and CMS Collaborations
Cross section measurements of top quark production in association with a vector boson in proton-proton collisions at $\sqrt{s}=13\,\mathrm{TeV}$ at the CERN LHC provide an important probe of the electroweak top quark couplings. In this contribution, recent results of the ATLAS and CMS Collaborations for the measurement of top quark pair and single top quark production in association with a photon or a Z boson are presented.

Determination of Proton Parton Distribution Functions using ATLAS Data / Zhang, Zhiqing (IJCLab, Orsay)
Using differential cross-section data of inclusive $W$ and $Z/\gamma^\ast$ boson production and of their production in association with jets, and differential cross-section data of top-quark pair production in the lepton + jets and dilepton channels in proton$-$proton collisions at the CERN Large Hadron Collider at center-of-mass energies of $\sqrt{s}=7$ and 8 TeV, together with deep inelastic scattering data from electron$-$proton collisions at the HERA collider, several determinations of parton distribution functions of the proton have been performed by the ATLAS experiment.
