Search for di-Higgs production at 13 TeV and prospects for HL-LHC / Schaarschmidt, Jana (Department of Physics, University of Washington, Seattle) /ATLAS Collaboration
The latest results on production of Higgs boson pairs at 13 TeV by the ATLAS experiment are reported, including a combination of six different decay modes. Results include bbtautau, bbbb, bbgamgam, bbWW, WWWW and WWgamgam final states, and they are interpreted both in terms of sensitivity to the SM and as limits on kappa_lambda, a scaling of the triple-Higgs interaction strength.

Search for heavy resonances decaying into a pair of Z bosons using 139 fb$^{−1}$ of proton-proton collisions at $\sqrt{s}$ = 13 TeV with the ATLAS detector / Lagouri, Theodota (Instituto de Alta Investigación, Universidad de Tarapacá) /ATLAS Collaboration
A search for heavy resonances decaying into a pair of Z bosons is presented. The search uses proton-proton collision data at a centre-of mass energy of 13 TeV collected from 2015 to 2018 that corresponds to an integrated luminosity of 139 fb$^{−1}$ which is the full data statistics collected by the ATLAS detector during the Run 2 of the Large Hadron Collider (LHC).

ATLAS measurement of CP Violation with Beauty mesons / Nikolaenko, Vladimir (Institute for High Energy Physics of the National Research Centre Kurchatov Institute, Protvino) /ATLAS Collaboration
A measurement of the B^0_s -> J/\psi \phi parameters using 80.5 fb^{-1} of integrated luminosity collected with the ATLAS detector from 13 TeV proton-proton collisions at the LHC is presented. The measured parameters include the CP-violating phase \phi_s, the width difference \Delta\Gamma_s between the B^0_s meson mass eigenstates and the average decay width \Gamma_s. [...]

Searches for New Long-lived Particles 
with the ATLAS detector / Oide, Hideyuki (Tokyo Institute of Technology) /ATLAS Collaboration
Various models of physics Beyond the Standard Model lead to signatures with long-lived particles, such that the decay of the new particle is at a significant distance from the collision point. These striking signatures provide interesting technical challenges due to their special reconstruction requirements as well as their unusual backgrounds. [...]

Searches for new phenomena 
in final states involving leptons and jets using the ATLAS detector / Wong, Vincent Wai Sum (University of British Columbia) /ATLAS Collaboration
Many beyond the Standard Model signatures predict new particles that decay into final state containing both leptons and jets. This talk will present new search results for massive particles by the ATLAS experiment using the full Run 2 dataset. [...]

ATLAS Searches for Resonances Decaying to Boson Pairs / Xu, Zhongyukun (Shandong University) /ATLAS Collaboration
Many extensions to the Standard Model predicts new particles decaying into two bosons (W, Z, photon, or Higgs bosons) making these important signatures in the search for new physics. Searches for such diboson resonances have been performed in final states with different numbers of leptons, photons and jets and b-jets where new jet substructure techniques to disentangle the hadronic decay products in highly boosted configuration are being used.

Highlights of top-quark production cross-section measurements with ATLAS at LHC: from precision to rarity / Panizzo, Giancarlo (INFN Gruppo Collegato di Udine, Dipartimento Politecnico di Ingegneria ed Architettura, Universita' di Udine, Udine) /ATLAS Collaboration
Top-quark production in proton-proton collisions at a center-of-mass energy of 13 TeV is measured with the data collected by the ATLAS detector over five orders of magnitude. The relatively large inclusive cross-section for the production of top-quark pair production is deter- mined using events in the lepton+jets channel and it reaches a relative uncertainty of 4.6% allowing for experimental scrutiny to theoretical calculations at next-to-next-to-leading order.

Searches for electroweak production of supersymmetric particles with the ATLAS detector / Sharma, Abhishek (University of Adelaide) /ATLAS Collaboration
Slides for a talk to be given at ICNFP 2020. The direct production of electroweak SUSY particles, including sleptons, charginos, and neutralinos, is a particularly interesting area with connections to dark matter and the naturalness of the Higgs mass. [...]

Searches for strong production of supersymmetric particles with the ATLAS detector / Zhu, Chenzheng (Institute of High Energy Physics, Chinese Academy of Sciences) /ATLAS Collaboration
Supersymmetry (SUSY) provides elegant solutions to several problems in the Standard Model, and searches for SUSY particles are an important component of the LHC physics program. Naturalness arguments for weak-scale supersymmetry favour supersymmetric partners of the gluons and third generation quarks with masses light enough to be produced at the LHC. [...]
