Effective field theory interpretation of off-shell Higgs boson production using $WW\to\ell\nu\ell\nu$ final states with the ATLAS detector
This note presents an interpretation of the measurement of off-shell Higgs boson production in the $H^\ast\to WW\to\ell\nu\ell\nu$ channel under the Standard Model Effective Field Theory (SMEFT) framework. [...]

Identification of the charge of heavy-flavour jets using transformers with the ATLAS experiment
Jet flavour identification has significantly been improved in the LHC community thanks to the introduction of novel transformer-based algorithms exploiting low-level tracking information and auxiliary training tasks to classify jets based on the flavour of quarks that initiated them. [...]

Deep Sets and event-level maximum-likelihood estimation for fast pile-up jet rejection at the ATLAS High Level Trigger
Multiple proton-proton interactions occur in the same bunch crossing at the LHC (“pile-up”), with the mean number of interactions per bunch crossing reaching up to about 60 in Run 3 and up to about 200 at the High-Luminosity LHC. [...]
