The ATLAS experiment has developed an extensive procedure based on Monte Carlo simulation and collision data to calibrate the response of large-radius jets. This paper describes the Run 2 calibration of large-radius jets reconstructed from Unified Flow Objects and groomed with the …

A search for non-resonant Higgs boson pair production (HH) in the $b\bar{b}τ^+τ^-$ final state is performed using 140 $fb^{-1}$ and 56 $fb^{-1}$ of proton-proton collision data at centre-of-mass energies of $\sqrt{s}$ = 13 TeV and 13.6 TeV, respectively, recorded by the ATLAS …

A search for heavy Majorana neutrinos coupling to third-generation leptons in vector boson scattering at the LHC is presented. The search is performed in the final state with a same-sign $ττ$, $eτ$ or $μτ$ pair using data of proton--proton collisions at $\sqrt{s}$ …

A search for pair-produced vector-like T quarks (VLQs) is presented. Each VLQ is assumed to decay into a top quark and an exotic (pseudo)scalar S. The search targets events with at least one resonant $S \to γγ$ decay and large summed transverse …

A search for spin-1 $ee$ and $μμ$ resonances in the high-mass range is presented. Two proton-proton ($pp$) collision datasets recorded by the ATLAS detector at CERN's Large Hadron Collider are utilised. A search is first performed using a dataset recorded at a …

A study of the production of the Higgs boson in association with either a top-quark pair ($t\bar{t}H$) or a single top quark ($tH$) in the $τ$-lepton-pair decay channel is presented. The analysis relies on final states featuring fully hadronic decays of the …

The $t$-channel production of a top quark in association with a $Z$ boson, $tZq$, is measured in the trilepton channel. The measured $pp \rightarrow t\ell^+\ell^-q$ process is defined for $m_{\ell\ell} > 30\,\text{GeV}$ and includes both resonant $Z$-boson production and non-resonant dilepton production. …

A search for new high-mass phenomena in events with a high-transverse-momentum photon and a jet is performed using data collected by the ATLAS experiment from proton-proton collisions at the LHC, with a centre-of-mass energy of 13 TeV. The analysis is based on …
