Bose-Einstein correlations of charged hadrons in proton-proton collisions at $\sqrt{s} = $ 13 TeV
Bose-Einstein correlations of charged hadrons are measured over a broad multiplicity range, from a few particles up to about 250 reconstructed charged hadrons in proton-proton collisions at $\sqrt{s} = $ 13 TeV. [...]

Measurement of the $t\bar{t}$ production cross-section and lepton differential distributions in $e\mu$ dilepton events from $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector
The inclusive top quark pair ($t\bar{t}$) production cross-section $\sigma_{t\bar{t}}$ has been measured in proton-proton collisions at $\sqrt{s}=13$ TeV, using $36.1$ fb$^{-1}$ of data collected in 2015-16 by the ATLAS experiment at the LHC. [...]

Mixed higher-order anisotropic flow and nonlinear response coefficients of charged particles in PbPb collisions at ${\sqrt {\smash [b]{s_{_{\mathrm {NN}}}}}} = $ 2.76 and 5.02 TeV
Anisotropies in the initial energy density distribution of the quark-gluon plasma created in high energy heavy ion collisions lead to anisotropies in the azimuthal distributions of the final-state particles known as collective flow. [...]

Search for new resonances in mass distributions of jet pairs using 139 fb$^{-1}$ of $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector
A search for new resonances decaying into a pair of jets is reported using the dataset of proton-proton collisions recorded at $\sqrt{s}=13$ TeV with the ATLAS detector at the Large Hadron Collider between 2015 and 2018, corresponding to an integrated luminosity of 139 fb$^{-1}$. [...]

Performance of the BRIL luminometers at CMS in Run 2 / Karacheban, Olena (CERN) /CMS Collaboration
CMS features three luminosity subdetectors capable of providing real-time (?online?) luminosity on a bunch-by-bunch level independently of the main CMS data acquisition system: the Fast Beam Conditions Monitor (BCM1F), the Hadron Forward (HF) calorimeter, and the Pixel Luminosity Telescope (PLT). These luminometers have operated since the beginning of Run 2 (2015-2018) at the LHC. [...]

Optimizing the performance of the CMS ECAL trigger for Runs 2 and 3 of the CERN LHC / Tishelman Charny, Abraham (Northeastern U.) /CMS Collaboration
The CMS Electromagnetic Calorimeter (ECAL) is a high resolution crystal calorimeter operating at the CERN LHC. It is responsible for the identification and precise reconstruction of electrons and photons in CMS, which were crucial in the discovery and subsequent characterization of the Higgs boson. [...]
