Search for emerging jets in $pp$ collisions at $\sqrt{s} = 13$ TeV with the ATLAS experiment / Ramirez-Berend, Ian Alejandro (Carleton University (CA)) /ATLAS Collaboration
A search is presented for emerging jets using $140$ fb$^{-1}$ of proton--proton collision data at $\sqrt{s} = 13$ TeV, collected by the ATLAS experiment between 2015 and 2018. The search looks for the existence of a dark sector with symmetries similar to those in quantum chromodynamics. [...]

The ATLAS Simulation R&D Programme for Run 4 / Novak, Tadej (Jozef Stefan Institute (SI)) /ATLAS Collaboration
Run 4 of the Large Hadron Collider will deliver a significantly larger dataset, which will, in turn, require the production of many more simulated Monte Carlo events. However, computing resources are not expected to scale at the same rate. [...]

Search for a new scalar decaying into new spin-1 bosons in four-lepton final states with the ATLAS detector / Aad, Georges (Marseille, CPPM) ; Abbott, Braden Keim (Oklahoma U.) ; Abeling, Kira (Gottingen U., II. Phys. Inst.) ; Abicht, Nils Julius (Dortmund U.) ; Abidi, Haider (Brookhaven) ; Aboulhorma, Asmaa (Mohammed V U., Agdal) ; Abramowicz, Halina (Tel Aviv U.) ; Abreu, Henso (Technion) ; Abulaiti, Yiming (New York U.) ; Abusleme, Angel (Chile U., Catolica) et al.
A search is conducted for a new scalar boson $S$, with a mass distinct from that of the Higgs boson, decaying into four leptons ($\ell =$ $e$, $\mu$) via an intermediate state containing two on-shell, promptly decaying new spin-1 bosons $Z_\text{d}$: $S \rightarrow Z_\text{d}Z_\text{d} \rightarrow 4\ell$, where the $Z_\text{d}$ boson has a mass between 15 and 300 GeV, and the $S$ boson has a mass between either 30 and 115 GeV or 130 and 800 GeV. The search uses proton-proton collision data collected with the ATLAS detector at the Large Hadron Collider with an integrated luminosity of 139 fb$^{-1}$ at a centre-of-mass energy of $\sqrt{s}=13$ TeV. [...]

Search for $t\bar{t}H/A \rightarrow t\bar{t}t\bar{t}$ production in proton-proton collisions at $\sqrt{s}=13$ TeV with the ATLAS detector / ATLAS Collaboration
A search is presented for a heavy scalar ($H$) or pseudo-scalar ($A$) predicted by the two-Higgs-doublet models, where the $H/A$ is produced in association with a top-quark pair ($t\bar{t}H/A$), and with the $H/A$ decaying into a $t\bar{t}$ pair. Events are selected requiring exactly one or two opposite-charge electrons or muons. [...]

Effects of K excess in microstructure of (Ba$_{0.6}$K$_{0.4}$)Fe$_{2}$As$_{2}$ superconducting powders / Bellingeri, Emilio (CNR-SPIN, Naples) ; Bernini, Cristina (CNR-SPIN, Naples) ; Loria, Federico (CNR-SPIN, Naples) ; Traverso, Andrea (CNR-SPIN, Naples) ; Leveratto, Alessandro (CNR-SPIN, Naples) ; Braccini, Valeria (CNR-SPIN, Naples) ; Ballarino, Amalia (CERN) ; Malagoli, Andrea (CNR-SPIN, Naples)
Iron-based superconductors (IBSs) are promising for high-field applications due to their exceptional characteristics, like ultrahigh upper critical field and minimal electromagnetic anisotropy. Creating multifilamentary superconducting wires with elevated transport critical current density is essential for practical use. [...]
