An implementation of Neural Simulation-Based Inference for Parameter Estimation in ATLAS
Neural Simulation-Based Inference (NSBI) is a powerful class of machine learning (ML)-based methods for statistical inference that naturally handles high-dimensional parameter estimation without the need to bin data into low-dimensional summary histograms. [...]

Measurement of Track Functions in ATLAS Run 2 Data
Measurements of jet substructure are key to probing the energy frontier at colliders, and many of them use track-based observables which take advantage of the angular precision of tracking detectors. [...]

Search for displaced leptons in 13 TeV and 13.6 TeV $pp$ collisions with the ATLAS detector
A search for leptons, displaced from the primary interaction vertex, including data collected at a center-of-mass energy of 13.6~TeV by the ATLAS experiment during Run~3 of the Large Hadron Collider is presented. [...]

Measurements of W H and Z H Higgs production with decays into bottom quarks and direct constraints on the charm Yukawa coupling with 13 TeV collisions in the ATLAS detector.
A study of the Higgs boson decaying into bottom quarks ($H \to b\bar{b}$) and charm quarks ($H \to c\bar{c}$) is performed, in the associated production channel of the Higgs boson with a $W$ or $Z$ boson, using $140\,\mathrm{fb}^{-1}$ of proton-proton collision data at $\sqrt{s} = 13\,\mathrm{TeV}$ collected by the ATLAS detector.

Search for electroweak production of vector-like leptons in multiple tau and b-jets final states in $pp$ collisions at $\sqrt{s}$=13 TeV with the ATLAS detector
A search for vector-like leptons pair-production is presented, considering their decays into a third-generation Standard Model (SM ) quark and the vector leptoquark ($U_1$) as predicted by a renormalisable and ultraviolet-complete extension of the SM, dubbed as the '4321' model. [...]
