Mixture Density Networks for tracking in dense environments on ATLAS / Khoda, Elham E (University of British Columbia) /ATLAS Collaboration
The high collision energy and luminosity of the LHC allow to study jets and hadronically-decaying tau leptons at extreme energies with the ATLAS detector. These signatures lead to topologies with charged particles with an angular separation smaller than the size of the ATLAS Inner Detector sensitive elements and consequently to a reduced track reconstruction efficiency.

Convolutional neural networks with event images for pileup mitigation / Brickwedde, Bernard (Institut fuer Physik, Universitaet Mainz) ; Nachman, Benjamin Philip (Lawrence Berkeley National Laboratory and University of California, Berkeley) /ATLAS Collaboration
The addition of multiple, nearly simultaneous proton proton collisions to hard-scatter collisions (in-time pileup) is a significant challenge for most physics analyses at the LHC. Many techniques have been proposed to mitigate the impact of pileup on jets and other reconstructed objects. [...]

The ATLAS Pixel Detector Upgrade at the HL-LHC / Pater, Joleen (School of Physics and Astronomy, University of Manchester) /ATLAS Collaboration
In 2025 the Large Hadron Collider will be shut down to allow upgrades to the accelerator and the experiments. After this ``Phase-II'' shutdown the LHC is expected to reach unprecedented values of instantaneous luminosity, with hundreds of interactions in each bunch crossing. [...]

Search for resonant WZ production in the fully leptonic final state in proton-proton collisions at sqrt(s) = 13 TeV with the ATLAS detector / ATLAS Collaboration
A search for a heavy resonance decaying into WZ in the fully leptonic channel (electrons and muons) is performed. It is based on proton–proton collision data collected by the ATLAS experiment at the Large Hadron Collider at a centre-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 36.1 fb^−1.

Searches for squarks and gluinos in R-parity conserving models at the LHC / Agapopoulou, Christina (LAL, Univ. Paris-Sud, IN2P3/CNRS, Universite Paris-Saclay) /ATLAS Collaboration
Supersymmetry is an extension of the Standard Model that provides an elegant solution to many of its shortcomings. Despite the absence of experimental evidence, supersymmetry continues to be a well motivated and studied part of the LHC program. [...]

Search for Higgs boson decays to BSM light bosons in four-lepton events with ATLAS / Boye, Diallo (University of Johannesburg, Department of Mechanical Engineering Science) /ATLAS Collaboration
Hidden sector or dark sector states appear in many extensions to the Standard Model, to provide a particle candidate for dark matter in universe or to explain astrophysical observations such as positron excess observed in the cosmic radiation flux. A hidden or dark sector can be introduced with an additional U(1)d dark gauge symmetry. [...]

Heavy Neutrino searches 
at ATLAS & CMS / Franchini, Matteo (Universita e INFN, Bologna) /ATLAS Collaboration
Several theories beyond the Standard Model predict the existence of heavy neutrinos trying to explain the experimental evidence of neutrino masses and that they are much smaller than their charged lepton partners. Principle models are the Left-right symmetric models (LRSM) and the Neutrino Minimal Standard Model (\{nu}MSM), which can include the seesaw mechanism, in particular the Type I seesaw mechanism, which introduces new heavy neutrino states without additional vector bosons, or the Type III seesaw mechanism which introduces additional heavy lepton triplets.

Heavy-flavour jet tagging in ATLAS / Windischhofer, Philipp Jonas (University of Oxford, Particle Physics) /ATLAS Collaboration
The identification of jets originating from heavy-flavor quarks (b-quark, c-quark) is central to the LHC physics program. High-performance heavy-flavor tagging is necessary both in precise standard model measurements as well as in searches for new physics. [...]
