In-situ measurements of the ATLAS large-radius jet response in 13 TeV pp collisions
The response of the ATLAS experiment to groomed large (R=1.0) radius jets is measured {\em in-situ} with 33 fb−1 of "$\sqrt$"=13 TeV LHC proton--proton collisions collected in 2016. [...]

Jet reclustering and close-by effects in ATLAS run II
The reconstruction of hadronically-decaying, high-$p_{T}$ $W$, $Z$ and Higgs bosons and top quarks is instrumental to exploit the physics potential of the ATLAS detector in $pp$ collisions at a centre-of-mass energy of 13 TeV at the Large Hadron Collider (LHC). [...]

Modelling of Track Reconstruction Inside Jets with the 2016 ATLAS $\sqrt{s}= 13$ TeV pp dataset
Inside the core of high transverse momentum jets, the particle density is so high that the tracks of charged particles begin to overlap, and due to the different charged particles, pixel clusters in the ATLAS inner detector begin to merge. [...]

Improving jet substructure performance in ATLAS using Track-CaloClusters
Jet substructure techniques play a critical role in ATLAS in searches for new physics, are increasingly important in measurements of the Standard Model, and are being utilized in the trigger. [...]
