The ALICE Service Work system / de Souza Pereira, Jomar Júnior (Rio de Janeiro Federal U.) ; Telesca, Adriana (CERN) ; Simão, Mario Günter (Rio de Janeiro Federal U.) ; Seixas, Jose Manuel (Rio de Janeiro Federal U.) ; Coura Torres, Rodrigo (Rio de Janeiro Federal U.)
The "A Large Ion Collider Experiment" (ALICE), one of the four large experiments at the European Organization for Nuclear Research (CERN), is responsible for studying the physics of strongly interacting matter and the quark-gluon plasma. In order to ensure the full success of ALICE operation and data taking during the Large Hadron Collider Runs 3 and 4, a list of tasks identified as Service Work is established and maintained. [...]

The ALICE Membership system / de Souza Pereira, Jomar Júnior (Rio de Janeiro Federal U.) ; Telesca, Adriana (CERN) ; Seixas, Jose Manuel (Rio de Janeiro Federal U.) ; Coura Torres, Rodrigo (Rio de Janeiro Federal U.)
With over 2000 active members from 174 institutes over 41 countries in the world, the ALICE experiment is one of the 4 large experiments at CERN. With such numerous interactions, the experiment management needs a way to record members’ participation history and their current status, such as employment, institutes, appointments, clusters and funding agencies, as well as to automatically generate the physics paper author list considering the experiment publication policy. [...]

Combination of measurements of the top quark mass from data collected by the ATLAS and CMS experiments at $\sqrt{s}=7$ and 8 TeV / ATLAS Collaboration
A combination of fifteen top quark mass measurements performed by the ATLAS and CMS experiments at the LHC is presented. The data sets used correspond to an integrated luminosity of up to 5 and 20$^{-1}$ of proton-proton collisions at center-of-mass energies of 7 and 8 TeV, respectively. [...]

Search for the non-resonant production of Higgs boson pairs via gluon fusion and vector-boson fusion in the $b\bar{b}\tau^+\tau^-$ final state in proton-proton collisions at $\sqrt{s} = 13$ TeV with the ATLAS detector / ATLAS Collaboration
A search for the non-resonant production of Higgs boson pairs in the $HH\rightarrow b\bar{b}\tau^+\tau^-$ channel is performed using 140 fb$^{-1}$ of proton-proton collisions at a centre-of-mass energy of $13$ TeV recorded by the ATLAS detector at the CERN Large Hadron Collider. The analysis strategy is optimised to probe anomalous values of the Higgs boson self-coupling modifier $\kappa_\lambda$ and of the quartic $HHVV$ ($V = W,Z$) coupling modifier $\kappa_{2V}$. [...]

Search for third-generation vector-like leptons in $pp$ collisions at $\sqrt{s} = 13\,\text{TeV}$ with the ATLAS detector / ATLAS Collaboration
A search for vector-like leptons in multilepton (two, three, or four-or-more electrons plus muons) final states with zero or more hadronic $\tau$-lepton decays is presented. The search is performed using a dataset of proton$-$proton collisions at a centre-of-mass energy of 13 TeV recorded by the ATLAS detector at the LHC, corresponding to an integrated luminosity of 139 fb$^{-1}$.

Search for pair production of third-generation leptoquarks decaying into a bottom quark and a $\tau $-lepton with the ATLAS detector / ATLAS Collaboration
A search for pair-produced scalar or vector leptoquarks decaying into a $b$-quark and a $\tau$-lepton is presented using the full LHC Run 2 (2015-2018) data sample of 139 fb$^{-1}$ collected with the ATLAS detector in proton-proton collisions at a centre-of-mass energy of $\sqrt{s}=13$ TeV. Events in which at least one $\tau$-lepton decays hadronically are considered, and multivariate discriminants are used to extract the signals. [...]

Measurements of the suppression and correlations of dijets in Xe+Xe collisions at $\sqrt{s_{NN}}$ = 5.44 TeV / ATLAS Collaboration
Measurements of the suppression and correlations of dijets is performed using 3 $\mu$b$^{-1}$ of Xe+Xe data at $\sqrt{s_{\mathrm{NN}}} = 5.44$ TeV collected with the ATLAS detector at the LHC.

Observation of Single-Top-Quark Production in Association with a Photon Using the ATLAS Detector / ATLAS Collaboration
This Letter reports the observation of single top quarks produced together with a photon using 139 fb$^{-1}$ of 13 TeV proton-proton collision data collected with the ATLAS detector at the Large Hadron Collider. The analysis uses the presence of a forward jet, characteristic of $t$-channel production, and separates the signal from the background with neural networks. [...]
