Searches for exotic resonances with top tagging / Maeda, Junpei (Kobe University) /ATLAS Collaboration
Several models of physics beyond the Standard Model contain preferential couplings to top quarks. We present an overview of searches for new physics containing boosted top quarks in the final state, using proton-proton collision data collected with the ATLAS detector at LHC at a centre-of-mass energy of 13 TeV.

CMOS Pixel Development for the ATLAS Experiment at HL-LHC / Gaudiello, Andrea (INFN Genova and Universita' di Genova, Dipartimento di Fisica) /ATLAS Collaboration
To cope with the rate and radiation environment expected at the HL-LHC new approaches are being developed on CMOS pixel detectors, providing charge collection in a depleted layer. They are based on: HV enabling technologies that allow to use high depletion voltages (HV-MAPS), high resistivity wafers for large depletion depths (HR-MAPS); radiation hard processed with multiple nested wells to allow CMOS electronics embedded with sufficient shielding into the sensor substrate and backside processing and thinning for material minimization and backside voltage application.

W/Top/Higgs-tagging in ATLAS / Norjoharuddeen, Nurfikri (University of Oxford, Particle Physics) /ATLAS Collaboration
We present updates of W, Top and Higgs tagging studies with the ATLAS detector. The performance of 2 variable taggers, HEPTopTagger and shower deconstruction are compared in Monte Carlo simulations. [...]

Large R jet reconstruction and calibration at 13 TeV with the ATLAS detector / Taenzer, Joe (Tel-Aviv University) /ATLAS Collaboration
Large-R jets are used by many ATLAS analyses working in boosted regimes. ATLAS Large-R jets are reconstructed from locally callibrated calorimeter topoclusters with the Anti-k_{t} algorithm with radius parameter R=1.0, and then groomed to remove pile-up with the trimming algorithm with f_{cut} 0.05 and subjet radius R=0.2.

Overview and developments for the Phase-II upgrade of the inner tracker of the ATLAS experiment / Hayward, Helen (University of Liverpool) /ATLAS Collaboration
In the high luminosity era of the Large Hadron Collider (HL-LHC), the instantaneous luminosity is expected to reach unprecedented values, resulting in about 200 proton-proton interactions in a typical bunch crossing. To cope with the resultant increase in occupancy, bandwidth and radiation damage, the ATLAS Inner Detector will be replaced by an all-silicon system, the Inner Tracker (ITk), aiming to provide tracking coverage up to |η|<4.

Module and electronics developments for the ATLAS ITK pixel system / Munoz Sanchez, Francisca Javiela (School of Physics and Astronomy, University of Manchester) /ATLAS Collaboration
ATLAS is preparing for an extensive modification of its detector in the course of the planned HL-LHC accelerator upgrade around 2025 which includes a replacement of the entire tracking system by an all-silicon detector (Inner Tracker, ITk). The five innermost layers of ITk will comprise of a pixel detector built of new sensor and readout electronics technologies to improve the tracking performance and cope with the severe HL-LHC environment in terms of occupancy and radiation.

Quark vs Gluon Jet Tagging at ATLAS / Rubbo, Francesco (SLAC National Accelerator Laboratory) /ATLAS Collaboration
Distinguishing quark-initiated from gluon-initiated jets is useful for many measurements and searches at the LHC. We present a quark-initiated versus gluon-initiated jet tagger from the ATLAS experiment using the number of reconstructed charged particles inside the jet. [...]

Identification of boosted top quarks and W bosons with Machine learning in ATLAS / Majersky, Oliver (Comenius University) /ATLAS Collaboration
We present techniques for the identification of hadronically-decaying W bosons and top quarks using high-level features as inputs to boosted decision trees and deep neural networks in the ATLAS experiment at sqrt(s)=13 TeV. The performance of these machine learning based taggers is compared in Monte Carlo simulation with various different tagging algorithms. [...]

Jet reclustering and close-by effects in ATLAS Run 2 / LeBlanc, Matthew Edgar (University of Victoria) /ATLAS Collaboration
The jet reclustering procedure propagates calibrations and uncertainties from the input jet collections through to the final \largeR jets, exploiting the detailed understanding of the input objects in order to provide greater flexibility at the physics analysis level. The forward-propagation of calibrations and uncertainties to reclustered jets eliminates the need to prepare a specific calibration for each large-R jet collection considered for use in analysis.

Identification of Hadronically-Decaying W Boson Top Quarks Using High-Level Features as Input to Boosted Decision Trees and Deep Neural Networks in ATLAS at #sqrt{s} = 13 TeV / Nitta, Tatsumi (Waseda University, Waseda Research Institute for Science and engineering (WISE)) /ATLAS Collaboration
The application of boosted decision trees and deep neural networks to the identification of hadronically-decaying W bosons and top quarks using high-level jet observables as inputs is investigated using Monte Carlo simulations. In the case of both boosted decision trees and deep neural networks, the use of machine learning techniques is found to improve the background rejection with respect to simple reference single jet substructure and mass taggers.
