Search for Exotic Decays of the Higgs Boson to Long-lived Particles Using Displaced Vertices in the ATLAS Inner Detector / Burzynski, Jackson Carl (University of Massachusetts (US)) /ATLAS Collaboration
A novel search for exotic decays of the Higgs boson to pairs of long-lived neutral particles, each decaying to a bottom quark pair, is performed using 139 fb$^{-1}$ of $\sqrt{s} = 13$ TeV proton-proton collision data collected with the ATLAS detector at the LHC. Events consistent with the production of a Higgs boson in association with a $Z$ boson are analyzed, with the leptonic decay of the $Z$ mitigating the trigger challenges associated with displaced objects.

13 TeV ATLAS Open Data: Using open education resources effectively / Serkin, Leonid (INFN Gruppo Collegato di Udine and ICTP, Trieste) /ATLAS Collaboration
The ATLAS Collaboration is releasing a new set of proton-proton collision data to the public for educational purposes. The data has been collected by the ATLAS detector at the Large Hadron Collider at a centre-of-mass energy $\sqrt{s}$ = 13 TeV during the year 2016 and corresponds to an integrated luminosity of 10 fb$^{-1}$.

Exploring the Dark Sector with the ATLAS Detector / Kay, Ellis (University of Victoria (CA)) /ATLAS Collaboration
The presence of a non-baryonic Dark Matter component in the Universe is inferred from the observation of its gravitational interaction. If Dark Matter interacts weakly with the Standard Model (SM) it could be produced at the LHC. [...]

Latest LHC results on Higgs Boson and multi-boson / Liu, Yanwen (University of Science and Technology of China (CN)) /ATLAS Collaboration
The LHC is currently the unique place to measure directly the properties of the Higgs boson, the only scalar particle in the Standard Model that breaks the electroweak gauge symmetry and attributes masses to all elementary particle. The interactions of the massive electroweak gauge bosons are profoundly related to the Higgs boson. [...]

A High-Granularity Timing Detector for the ATLAS Phase-II upgrade / Aboulhorma, Asmaa (Universite Mohammed V (MA)) /ATLAS Collaboration
The increase of the particle flux (pile-up) at the HL-LHC with instantaneous luminosities up to L ~ 7.5 × $10^{34} cm^{−2}s^{−1}$ will have a severe impact on the ATLAS detector reconstruction and trigger performance. The end-cap and forward region where the liquid Argon calorimeter has coarser granularity and the inner tracker has poorer momentum resolution will be particularly affected. [...]

The ATLAS Level-1 Topological Processor: Experience and upgrade plans / Martinez Suarez, Paula (The Barcelona Institute of Science and Technology (BIST) (ES)) /ATLAS Collaboration
During Run-2 the Large Hadron Collider (LHC) has provided, at the World's energy frontier, proton-proton collisions to the ATLAS experiment with high instantaneous luminosity of up to $2.1\times 10^{34}$ cm$^{-2}$s$^{-1}$, placing stringent operational and physical requirements on the ATLAS trigger system in order to reduce the 40 MHz collision rate to a manageable event storage rate of 1 kHz, while not rejecting interesting collisions. The Level-1 trigger is the first rate-reducing step in the ATLAS trigger system with an output rate of up to 100 kHz and decision latency of less than 2.5 microseconds. [...]

The Phase-1 Upgrade of the ATLAS Level-1 Calorimeter Trigger / Myers, Greg (Indiana University (US)) ; ATLAS Collaboration /ATLAS Collaboration
The ATLAS level-1 calorimeter trigger (L1Calo) is a hardware based system that identifies events containing calorimeter-based physics objects, including electrons, photons, taus, jets, and missing transverse energy. In preparation for Run 3, when the LHC will run at higher energy and instantaneous luminosity, L1Calo is currently implementing a significant programme of planned upgrades. [...]

Firmware of the ATLAS Level-0 Endcap Muon Trigger for HL-LHC / Mitsumori, Yuki (Nagoya University (JP)) /ATLAS Collaboration
The design and the status of the development of the Level-0 endcap muon trigger firmware for the ATLAS experiment at the HL-LHC are presented. The firmware reconstructs muon candidates with an improved momentum resolution by exploiting all hit data from Thin Gap Chambers (TGCs) to be available at XCVU13P FPGA mounted on the trigger and readout boards.

Constraining the Dark Sector with the Mono-jet signature / Pompa Pacchi, Elena (Sapienza Universita e INFN, Roma I (IT)) /ATLAS Collaboration
Several Dark Sector models predict the existence of particles with macroscopic life-times, that can lead to final states with large missing transverse momentum recoiling against at least one highly energetic jet, a signature that is often referred to as a mono-jet. The RECAST framework is used to re-interpret the recent ATLAS mono-jet search, based on 139fb-1 of pp collisions collision data at centre of mass energy of 13 TeV, in terms of Dark Sector models not studied in the original work.
