 Measurement of $\gamma\gamma \rightarrow \mu^{+}\mu^{-}$ pairs in non-ultra peripheral Pb+Pb collisions with the ATLAS detector / Gilbert, Benjamin Jacob (Nevis Laboratory, Columbia University) ; Mohapatra, Soumya (Nevis Laboratory, Columbia University) ; Cole, Brian (Nevis Laboratory, Columbia University) /ATLAS Collaboration ATLAS measurements of dimuons produced via γγ scattering processes in inelastic, non-ultra-peripheral Pb+Pb collisions at 5.02 TeV are presented using an integrated luminosity of 1.9 nb−1. The γγ→μ+μ− pairs are identified via selections on pair momentum asymmetry and acoplanarity, and the contribution from the heavy flavor decay background is estimated using both template and asymptotic fit methods.

 Light-by-light scattering in ultra-peripheral Pb+Pb collisions in the ATLAS experiment / Ogrodnik, Agnieszka (AGH University of Science and Technology, Faculty of Physics and Applied Computer Science, Krakow) /ATLAS Collaboration The ultra-peripheral Pb+Pb collisions at $\sqrt{s_{\mathrm{NN}}} = 5.02$ TeV performed at the ATLAS experiment are used to study a rare light-by-light scattering process, $\gamma\gamma\rightarrow\gamma\gamma$, allowed in Quantum Electrodynamics via a loop diagram. The poster summarises recent light-by-light measurements conducted using a combination of 2015 and 2018 datasets recorded by the ATLAS experiment, corresponding to an integrated luminosity of 2.2 n$b^{-1}$.

 Measurement of the sensitivity of two particle correlations in pp collisions at $\sqrt{s}=13$~TeV to the presence of jets with the ATLAS detector / Yin, Pengqi (Nevis Laboratory, Columbia University) /ATLAS Collaboration Measurements of two-particle correlations in $pp$ collisions show the presence of long-range correlations along $\Delta\eta$ that are strikingly similar to those seen in heavy-ion collisions. In heavy-ion collisions, the long-range correlations are known to arise from the collective dynamics of the produced quark-gluon plasma (QGP).

 Flow and transverse momentum correlations in Pb+Pb and Xe+Xe collisions with ATLAS / Bhatta, Somadutta (Stony Brook University) /ATLAS Collaboration Fluctuations of event-wise average transverse momentum ([$p_T$]) and the harmonic flow ($v_n$) carry important information about initial-state geometry. Collisions of nuclei with large quadrapole deformation are predicted to produce an initial state with enhanced shape and size fluctuations, and result in non-trivial correlation between $v_n$ and [$p_T$] in the final state.

 Production of W, Z, and charged hadrons  in Pb+Pb collisions with the ATLAS detector / Grabowska-Bold, Iwona (AGH University of Science and Technology, Faculty of Physics and Applied Computer Science, Krakow) /ATLAS Collaboration Measurements of $W^{\pm}$, $Z$, and charged-hadron production in Pb+Pb collisions at $\sqrt{s_{NN}}=5.02$ TeV are presented using data recorded by the ATLAS experiment at the LHC in 2015 corresponding to a total integrated luminosity of 0.49\,nb${}^{-1}$. The the electro-weak (EW) bosons are reconstructed in both the electron and muon decay channels.

 Measurement of the Higgs Simplified Template Cross Sections using H -> yy decays with the ATLAS experiment / Franco, Luca (LAPP, Univ. Grenoble Alpes, Univ. Savoie Mont Blanc, CNRS/IN2P3, Annecy) /ATLAS Collaboration The measurement of Higgs Simplified Template Cross Sections (STXS), which are cross sections defined in exclusive kinematic regions and topologies for the different Higgs boson production processes, in the H->yy decay channel by the ATLAS experiment at the LHC is presented. The analysis relies on categorizing events according to their topology to measure the STXS. [...] ATL-PHYS-SLIDE-2021-002.- Geneva : CERN, 2021 - 29 p.
