A search for dark matter produced in association with a dark Higgs boson decaying into a Higgs boson pair in 3$b$ or 4$b$ final states using $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector
A search is performed for dark matter particles produced in association with a resonant pair of Higgs bosons using 140 fb$^{-1}$ of proton-proton collisions at a centre-of-mass energy of 13 TeV recorded by the ATLAS detector at the Large Hadron Collider. [...]

Heavy Ion Ultra Peripheral Collisions at CMS and ATLAS / Veres, Gabor (Eotvos U.) /ATLAS and CMS Collaborations
Recent results from the ATLAS and CMS Collaborations will be summarized, related to ultraperipheral heavy ion collisions. Those include studies of nuclear parton distributions using various final states like coherent and incoherent J/Psi, coherent Upsilon and phi, open charm, and photonuclear jets. [...]

Standard Model multibosons / Paspalaki, Garyfallia (Purdue U.) /ATLAS and CMS Collaborations
The study of multi-boson processes at the ATLAS experiments at the Large Hadron Collider (LHC) provides crucial tests of the Standard Model (SM) at the TeV scale. These measurements, including differential cross-sections and vector boson scattering (VBS), are essential for validating existing models and probing the mechanisms of electroweak symmetry breaking.

Search for single production of vector-like quarks decaying into $W(\ell\nu)b$ in $pp$ collisions at $\sqrt{s} = 13$ TeV with the ATLAS detector / ATLAS Collaboration
A search for single production of a vector-like quark $Q$, which could be either a singlet $T$, with charge $\tfrac23$, or a $Y$ from a $(T,B,Y)$ triplet, with charge $-\tfrac43$, is performed using data from proton--proton collisions at a centre-of-mass energy of 13 TeV. [...]

Measurements of differential cross-sections of $WbWb$ production in the dilepton channel in $pp$ collisions at $\sqrt{s}$ = 13 TeV using the ATLAS detector / ATLAS Collaboration
At the Large Hadron Collider, the $WbWb$ final state is expected to be dominated by $t\bar{t}$ production with a contribution from single-top processes. [...]

Supersymmetry searches at ATLAS and CMS / Kwon, Hyejin (Antwerp U.) /ATLAS and CMS Collaborations
This document presents recent results from the ATLAS and CMS experiments at the CERN Large Hadron Collider (LHC) on supersymmetry (SUSY) searches. These searches provide results with some non-conventional SUSY search assumptions such as with compressed mass scenario or with long-lived particle scenario. [...]
