Expected performance for displaced Lepton Jets: ATLAS trigger and reconstruction efficiency in LHC 2015 run.
Several models of physics beyond the Standard Model predict neutral particles that decay to final states consisting of collimated jets of light leptons and hadrons (so-called ``Lepton Jets''). [...]

Estimate of the $m_H$ shift due to interference between signal and background processes in the $H \rightarrow \gamma\gamma$ channel, for the $\sqrt{s} = 8$ TeV dataset recorded by ATLAS
In the context of precision measurements of the properties of the Higgs boson, one of the most fundamental parameters is the knowledge of its mass. [...]

Prospective results for vector-boson fusion-mediated Higgs-boson searches in the four lepton final state at the High Luminosity Large Hadron Collider
The High Luminosity Large Hadron Collider is expected to be completed and operational in the second half of 2026, and will necessitate substantial upgrades to the ATLAS inner tracker detector. [...]

Measurement of track reconstruction inefficiencies in the core of jets via pixel dE/dx with the ATLAS experiment using $\sqrt{s}=13$ TeV $\textit{pp}$ collision data
The inefficiency of the ATLAS charged particle reconstruction in the core of jets is studied as a function of the transverse momentum of the jet between 200 GeV and 1600 GeV, using proton-proton data collected by the ATLAS experiment from the LHC in 2015 at a center-of-mass energy of $\sqrt{s}=13$ TeV.

Study of higher-order QCD corrections in the $gg\rightarrow H\rightarrow VV$ process
Several studies have shown that the high-mass off-peak regions in the $H\rightarrow ZZ$ and $H\rightarrow WW$ channels above the $VV$ mass threshold ($V=W,Z$) have sensitivity to off-shell Higgs production and interference effects. [...]
