Correlations between flow and transverse momentum in Pb+Pb and Xe+Xe collisions with ATLAS / Behera, Arabinda (Stony Brook University) /ATLAS Collaboration
The measurement of the correlation between flow harmonics $v_n$ and average transverse momentum $p_\mathrm{T}$ for n = 2, 3 and 4 with the ATLAS detector at the LHC is presented, based on 3$\mu \mathrm{b}^{-1}$ Xe+Xe collisions at $\sqrt{s_{\mathrm{NN}}}=5.44$ TeV and 22$\mu \mathrm{b}^{-1}$ Pb+Pb collisions at $\sqrt{s_{\mathrm{NN}}}=5.02$ TeV. This correlation is characterized by the Pearson correlation coefficient, $\rho(v_n^2,[p_\mathrm{T}])$, which quantifies the strength of the correlation between $v_n^2$ and event-by-event average $p_\mathrm{T}$, $[p_\mathrm{T}]$.

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. [...]
