 Unified Flow performances in ATLAS / Lalloue, Nathan (Centre National de la Recherche Scientifique (FR)) /ATLAS Collaboration The reconstruction and calibration of hadronic final states is an extremely challenging experimental aspect of measurements and searches at the LHC. This talk summarizes the latest results from ATLAS for jet reconstruction and calibration of Anti-kt R=0.4 jets. [...] ATL-PHYS-SLIDE-2022-376.- Geneva : CERN, 2022 - 1 p.

 New results on the heavy-flavor and quarkonia measurements with ATLAS / Zou, Wenkai (Columbia University (US)) /ATLAS Collaboration Measurements of heavy-flavor hadron production in heavy-ion collisions provide a powerful tool to study both initial-state effects on heavy-quark production and final-state interactions between heavy-quarks and the quark-gluon plasma. These measurements are performed with the ATLAS detector at the LHC and capitalize on the large statistics of the Run 2 Pb+Pb dataset.

 Search for long-lived neutral particles in pp collisions at $\sqrt{s}$ = 13 TeV that decay into displaced hadronic jets in the ATLAS calorimeter / Sanchez Sebastian, Victoria (Univ. of Valencia and CSIC (ES)) /ATLAS Collaboration Many extensions of the Standard Model predict the existence of long-lived particles leading to highly unconventional experimental signatures for which standard searches are not sensitive. In this poster we present a search for pairs of neutral long-lived particles decaying hadronically and giving rise to displaced jets. [...] ATL-PHYS-SLIDE-2022-374.- Geneva : CERN, 2022 - 1 p.

 The new Muon-to-Central-Trigger-Processor Interface at ATLAS / Afik, Yoav (CERN) ; ATLAS TDAQ Collaboration /ATLAS Collaboration The ATLAS trigger system includes a Level-1 (L1) trigger based on custom electronics and firmware, and a high-level trigger based on off-the-shelf hardware and processing software. The L1 trigger system uses information from the calorimeters and from the muon trigger detectors, consisting of Resistive Plate Chambers in the barrel, and of Thin-Gap Chambers, small-strip Thin-Gap Chambers and MicroMegas in the endcaps.

 Search for long-lived particles in events with a displaced vertex using the ATLAS detector with the full Run2 dataset / Wakida, Moe (Nagoya University (JP)) /ATLAS Collaboration A large number of physics models that extend the Standard Model predict the existence of new, massive, long-lived particles. Searches for these processes may target its decay products at a significant distance from the collision point. [...] ATL-PHYS-SLIDE-2022-372.- Geneva : CERN, 2022 - 1 p.

 Search for electroweak production of supersymmetric particles with the ATLAS detector / Nobe, Takuya (University of Tokyo (JP)) /ATLAS Collaboration 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. The small production cross sections lead to difficult searches, despite relatively clean final states.

 Measurement of collective dynamics in pp, Xe+Xe, and Pb+Pb collisions with the ATLAS detector / Bold, Tomasz (AGH University of Science and Technology (PL)) /ATLAS Collaboration This talk presents ATLAS measurements of collective, flow phenomena in a variety of collision systems, including pp collisions at 13 TeV, Xe+Xe collisions at 5.44 TeV, and Pb+Pb collisions at 5.02 TeV. These include measurements of vn-[pT] correlations in Xe+Xe and Pb+Pb, which carry important information about the initial-state geometry of the Quark-Gluon Plasma and can potentially shed light on any quadrupole deformation in the Xe nucleus; measurements of flow decorrelations differential in rapidity, which probe the longitudinal structure of the colliding system; and measurements of the sensitivity of collective behavior in pp collisions to the presence of jets, which seek to distinguish the role that semi-hard processes play in the origin of these phenomena in small systems.

 Proton parton distribution functions using ATLAS data / Conroy, Eimear Isobel (University of Oxford (GB)) /ATLAS Collaboration Precise knowledge of proton parton distribution functions is a crucial element of accurate predictions of both Standard Model and Beyond Standard Model physics at hadron colliders such as the LHC. We present a PDF fit at next-to-next-to-leading order in QCD demonstrating the constraining power of a diverse range of ATLAS measurements, in combination with deep-inelastic scattering data from HERA, on the parton distributions within the proton.

 Not a jet all the way - a search for semi-visible jets in non-resonant production mode in ATLAS / Sinha, Sukanya (University of the Witwatersrand (ZA)) /ATLAS Collaboration Collider searches for dark matter (DM) so far have mostly focussed on scenarios, where DM particles are produced in association with heavy standard model (SM) particles or jets. However, no deviations from SM predictions have been observed so far.
