Test of lepton flavour universality in $W$-boson decays into electrons and $\tau$-leptons using $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector / ATLAS Collaboration
A measurement of the ratio of the branching fractions, $R_{\tau/e} = B(W \to \tau \nu)/ B(W \to e \nu)$, is performed using a sample of $W$ bosons originating from top-quark decays to final states containing $\tau$-leptons or electrons. [...]

Cross-section measurements for the production of a $W$-boson in association with high-transverse-momentum jets in $pp$ collisions at $\sqrt{s}$= 13 TeV with the ATLAS detector / ATLAS Collaboration
A set of measurements for the production of a $W$-boson in association with high-transverse-momentum jets is presented using 140 fb$^{-1}$ of proton-proton collision data at a centre-of-mass energy of $\sqrt{s}=13$ TeV collected by the ATLAS detector at the LHC. [...]

An integrated flux-symmetric spectrometer-magnet system for the SND@LHC experiment upgrade / SND@LHC Collaboration
The proposed upgrade of the SND@LHC experiment for the High Luminosity phase of the LHC (HL-LHC) will strongly benefit from the presence of a magnetized region, allowing for muon momentum and chargemeasurement. In this paper we describe an iron core magnet system that is partly integrated with the calorimeter and that is designed to respect the strict constraints from the available space in the experimental cavern, power consumption, and field requirements.Semi-analytical tools are introduced to explore the parameter space, in order to define the primary design options. [...]

Precision calibration of calorimeter signals in the ATLAS experiment using an uncertainty-aware neural network / ATLAS Collaboration
The ATLAS experiment at the Large Hadron Collider explores the use of modern neural networks for a multi-dimensional calibration of its calorimeter signal defined by clusters of topologically connected cells (topo-clusters). [...]

An implementation of neural simulation-based inference for parameter estimation in ATLAS / ATLAS Collaboration
Neural simulation-based inference is a powerful class of machine-learning-based methods for statistical inference that naturally handles high-dimensional parameter estimation without the need to bin data into low-dimensional summary histograms. [...]

We report the observation of neutrino interactions without final state muons at the LHC, with a significance of 6.4\,$\sigma$. A data set of proton-proton collisions at $\sqrt{s}= 13.6$\,TeV collected by \SND in 2022 and 2023 is used, corresponding to an integrated luminosity of 68.6\,fb$^{-1}$. [...]
