Observation of $W^{+}W^{-}\gamma$ production in $pp$ collisions at $\sqrt{s}$ = 13 TeV with the ATLAS detector and constraints on anomalous quartic gauge-boson couplings
This Letter reports the observation of $W^{+}W^{-}\gamma$ triboson production in 140 fb$^{-1}$ of data collected by the ATLAS detector from proton-proton collisions at a centre-of-mass energy of $\sqrt{s}$ = 13 TeV at the LHC. [...]

Measurement of the $W$-boson angular coefficients and transverse momentum in $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector
The angular distributions of Drell-Yan lepton pairs provide sensitive probes of the underlying dynamics of quantum chromodynamics (QCD) effects in vector-boson production. [...]

Search for Higgs bosons produced in association with a high-energy photon via vector-boson fusion and decaying to a pair of $b$-quarks in the ATLAS detector
A search for Standard Model Higgs bosons produced in association with a high-energy photon and decaying to $b\bar{b}$ is performed using 133 fb$^{-1}$ of $\sqrt{s}=13$ TeV $pp$ collision data collected with the ATLAS detector at the Large Hadron Collider at CERN. [...]

Observation of structures in the $J/\psi +\psi(2S)$ mass spectrum with the ATLAS detector
A search for resonant structures in the $J/\psi +\psi$(2S) mass spectrum is performed using proton-proton collision data at $\sqrt{s}=13$ TeV, corresponding to an integrated luminosity of 140 fb$^{-1}$, recorded by the ATLAS experiment at the LHC. [...]

Measurements of $ {\mathrm{t}\overline{\mathrm{t}}} \mathrm{W} $ differential cross sections and the leptonic charge asymmetry at $ \sqrt{s}= $ 13 TeV
Measurements of properties of top quark-antiquark pair production in association with a W boson in proton-proton collisions at a center-of-mass energy of 13 TeV are presented, using a data sample corresponding to an integrated luminosity of 138 fb$ ^{-1} $, recorded by the CMS experiment at the CERN LHC.

DEEPMET: Improving missing transverse momentum estimation with a deep neural network / CMS Collaboration
At hadron colliders, the net transverse momentum of particles that do not interact with the detector (missing transverse momentum, $ {\vec p}_{\mathrm{T}}^{\, \text{miss}} $) is a crucial observable in many analyses. [...]
