Measurement of the effective leptonic weak mixing angle / LHCb Collaboration
Using $pp$ collision data at $\sqrt{s}=13$~TeV, recorded by the LHCb experiment between 2016 and 2018 and corresponding to an integrated luminosity of $5.4$~fb$^{-1}$, the forward-backward asymmetry in the $pp \to Z/\gamma^{*} \to \mu^+\mu^-$ process is measured. The measurement is carried out in ten intervals of the difference between the muon pseudorapidities, within a fiducial region covering dimuon masses between $66$ and $116$ GeV, muon pseudorapidities between $2.0$ and $4.5$ and muon transverse momenta above $20$ GeV.

A search for R-parity-violating supersymmetry in final states containing many jets in pp collisions at $ \sqrt{s} $ = 13 TeV with the ATLAS detector / ATLAS Collaboration
A search for R-parity-violating supersymmetry in final states with high jet multiplicity is presented. The search uses $140\, {\text{fb}^{-1}}$ of proton-proton collision data at $\sqrt{s} = 13\, \text{TeV}$ collected by the ATLAS experiment during Run 2 of the Large Hadron Collider. [...]

Measurement of the $B_s^0 \to \mu\mu$ Effective Lifetime with the ATLAS Detector / ATLAS Collaboration
This paper reports the first ATLAS measurement of the $B_s^0 \to \mu\mu$ effective lifetime. The measurement is based on the data collected in 2015-2016, amounting to 26.3 fb$^{-1}$ of 13 TeV LHC proton-proton collisions. [...]

Accuracy versus precision in boosted top tagging with the ATLAS detector / ATLAS Collaboration
The identification of top quark decays where the top quark has a large momentum transverse to the beam axis, known as \textit{top tagging}, is a crucial component in many measurements of Standard Model processes and searches for beyond the Standard Model physics at the Large Hadron Collider. Machine learning techniques have improved the performance of top tagging algorithms, but the size of the systematic uncertainties for all proposed algorithms has not been systematically studied. [...]

Using pile-up collisions as an abundant source of low-energy hadronic physics processes in ATLAS and an extraction of the jet energy resolution / ATLAS Collaboration
During the 2015-2018 data-taking period, the Large Hadron Collider delivered proton-proton bunch crossings at a centre-of-mass energy of 13 TeV to the ATLAS experiment at a rate of roughly 30 MHz, where each bunch crossing contained an average of 34 independent inelastic proton-proton collisions. The ATLAS trigger system selected roughly 1 kHz of these bunch crossings to be recorded to disk. [...]

Search for new particles in events with a hadronically decaying W or Z boson and large missing transverse momentum at $ \sqrt{s} $ = 13 TeV using the ATLAS detector / ATLAS Collaboration
A search is presented for new particles produced in proton-proton collisions at a centre-of-mass energy of 13 TeV that result in final states comprising a massive vector ($W$ or $Z$) boson that decays hadronically and large missing transverse momentum. The data sample was collected with the ATLAS experiment at the Large Hadron Collider from 2015 to 2018 and corresponds to an integrated luminosity of 140 fb$^{-1}$. [...]

Search for a resonance decaying into a scalar particle and a Higgs boson in final states with leptons and two photons in proton-proton collisions at $\sqrt s=13$ TeV with the ATLAS detector / ATLAS Collaboration
A search for a hypothetical heavy scalar particle, $X$, decaying into a singlet scalar particle, $S$, and a Standard Model Higgs boson, $H$, using 140 fb$^{-1}$ of proton-proton collision data at the centre-of-mass energy of 13 TeV recorded with the ATLAS detector at the LHC is presented.

Search for lepton-flavour violation in high-mass dilepton final states using 139 $\mathrm{fb}^{-1}$ of $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector / ATLAS Collaboration
A search is performed for a heavy particle decaying into different-flavour, dilepton final states, using 139 $\mathrm{fb}^{-1}$ of proton--proton collision data at $\sqrt{s}=13$ TeV collected in 2015--2018 by the ATLAS detector at the Large Hadron Collider. Final states with electrons, muons and hadronically decaying tau leptons are considered ($e\mu$, $e\tau$ or $\mu\tau$). [...]

This paper describes a measurement of the jet radius dependence of the dijet momentum balance between leading back-to-back jets in 1.72 $nb^{-1}$ of Pb+Pb collisions collected in 2018 and 255 pb$^{-1}$ of $pp$ collisions collected in 2017 by the ATLAS detector at the LHC. Both data sets were collected at $ \sqrt{s_{\rm NN}}=$ 5.02 TeV. [...]
