Reconstruction techniques in supersymmetry searches with soft objects in the ATLAS experiment / Chen, Shion (Department of Physics and Astronomy, University of Pennsylvania) /ATLAS Collaboration
Many supersymmetric scenarios feature final states with non-standard final state objects. When considering compressed scenarios, involving sparticle spectra with small mass-splittings and decays to low-momentum leptons or jets, analyses depend on novel methods for the reconstruction of these very soft particles.

Boosted object identification and their usage in searches for new physics in ATLAS / Yang, Yi-lin (International Center for Elementary Particle Physics and Department of Physics, The University of Tokyo) /ATLAS Collaboration
Many searches for physics beyond the Standard Model make use of large radius jets to reconstruct hadronically decaying electroweak bosons or top quarks with high transverse momenta. Algorithms have been developed in ATLAS that take advantage of the different radiation pattern within the large radius jet depending on the initiating particle to efficiently reject quark- or gluon-initiated jets from background processes.

The study of the rare decays $B^{0}_{(s)} \rightarrow \mu^{+}\mu^{-}$ at $\sqrt{s} = 13$ TeV with the ATLAS detector / Ghneimat, Mazuza (Department Physik, Universitaet Siegen) /ATLAS Collaboration
The flavour-changing neutral currents of the rare decays $B^{0}_{(s)} \rightarrow \mu^{+}\mu^{-}$ provide a favourable environment to observe new physics. The study of these decays, using the data collected by the ATLAS detector, is presented. [...]

Searches for direct pair production of stops and sbottom with the ATLAS detector / Stevenson, Thomas James (University of Sussex) /ATLAS Collaboration
Naturalness arguments for weak-scale supersymmetry favour supersymmetric partners of the third generation quarks with masses light enough to be produced at the LHC. The ATLAS experiment has a variety of analyses devoted to stop and sbottom direct production exploiting novel reconstruction and analysis techniques. [...]

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..
