Triggering on Hadronic Signatures with the ATLAS Detector / Carlson, Benjamin Taylor (University of Pittsburgh) /ATLAS Collaboration
At the Large Hadron Collider, many important searches for new particles and Standard Model measurements probe final states with hadronic jets and missing transverse momentum. Such events are also fundamental for precision calibration. [...]

Search for Type-III SeeSaw heavy leptons in multileptonic final states using 139 fb$^{-1}$ of pp collisions at $\sqrt(s)$ = 13 TeV with the ATLAS detector / Carratta, Giuseppe (Universita e INFN, Bologna) /ATLAS Collaboration
The discovery of neutrino oscillations implies they have non-null masses much smaller than charged leptons. This is difficult to accommodate in a natural way through a pure Standard Model Yukawa coupling to the Higgs field. [...]

Search for Higgs boson in the final state with two leptons and a photon produced in pp collisions at a center-of-mass energy of 13 TeV with the ATLAS detector / Basalaev, Artem (DESY, Hamburg and Zeuthen) /ATLAS Collaboration
A search for Higgs boson in the final state with two leptons (electrons or muons) and a photon produced in pp collisions at a center-of-mass energy of 13 TeV with the ATLAS detector is presented. Estimates of Higgs boson signal and background contribution are performed for three-body invariant mass distribution. [...]

Measurement of four-top-quarks production with the ATLAS Detector / Asbah, Nedaa (Harvard University) /ATLAS Collaboration
A search for four-top-quark production using proton-proton collision data at a centre-of-mass energy of 13 TeV collected by the ATLAS detector corresponding to an integrated luminosity of 139 fb^{−1} for the same-sign lepton pair or at least three leptons and 36 fb^{−1} for the single-lepton and opposite-sign dilepton channels. In the multilepton final states, the four-top-quark production cross section is measured to be 24^{+7}_{−6} fb, corresponding to an observed (expected) signal significance of 4.3 (2.4) standard deviations and providing evidence for this process..

Search for SUSY with missing transverse momentum and multiple b-jets with the ATLAS detector / Ghasemi Bostanabad, Meisam (University of Victoria) /ATLAS Collaboration
A search for supersymmetry involving the pair production of gluinos decaying via third generation squarks into the lightest neutralino is presented. The analysis uses the large hadron collider proton-proton collision data at a center-of-mass 13 TeV with an integrated luminosity of 79.8 fb^-1 collected with the ATLAS detector in 2015, 2016 and 2017.

Measurements of inclusive four-lepton production at ATLAS (Poster Draft for ICHEP2020) / Liu, Xiaotian (University of Science and Technology of China) /ATLAS Collaboration
Measurements of the four-lepton invariant mass spectrum are made with the ATLAS detector, using proton-proton collisions at √s=13 TeV delivered by the Large Hadron Collider. The measurement is done selecting events that contain two same-flavour opposite-sign lepton pairs. [...]

Measurement of jet substructure and jet fragmentation using the ATLAS detector / Roloff, Jennifer Kathryn (Brookhaven National Laboratory (BNL)) /ATLAS Collaboration
Measurements of the internal properties of jets allow QCD to be studied at a new regime at a hadron collider. In this talk, we discuss recent measurements jet substructure and jet fragmentation that were performed using data collected by the ATLAS experiment at a centre-of-mass energy of √s=13TeV. [...]

Measurements of soft-QCD and diffractive processes with ATLAS / Staszewski, Rafal (Institute of Nuclear Physics Polish Academy of Sciences, Krakow) /ATLAS Collaboration
In this talk we present various measurements sensitive to non-perturbative physics performed using data collected by the ATLAS experiment at the LHC. Inclusive single diffractive dissociation (pp->pX) is studied using data collected by the ATLAS forward spectrometer spectrometers, while charged particles from the dissociative system (X) are reconstructed and measured using the ATLAS inner tracking detector and calorimeters.

JetCalibration_ICHEP2020 / Hansen, Eva (Lunds universitet, Fysiska institutionen) /ATLAS Collaboration
Hadronic signatures are critical to the ATLAS physics program and many Standard Model measurements and searches for new physics are dominated by the uncertainties on the jet energy scale and resolution or the jet mass scale and resolution. The procedure of calibrating jets in ATLAS using both simulation and in situ techniques will be presented for both anti-kt R = 0.4 and R = 1.0 jets. [...]

Dark Matter searches with the ATLAS detector / Carlson, Benjamin Taylor (University of Pittsburgh) /ATLAS Collaboration
The presence of a non-baryonic dark matter (DM) component in the Universe is inferred from the observation of its gravitational interaction. If dark matter interacts weakly with the Standard Model it would be produced at the LHC, escaping the detector and leaving a large missing transverse momentum as their signature. [...]
