title: "Figure 3a" of "Measurements of azimuthal anisotropy of nonprompt D$^0$ mesons in PbPb collisions at $\sqrt{s_\mathrm{NN}}$ = 5.02 TeV"

description: The elliptic, $v_2$ flow coefficients of nonprompt $\mathrm{D^0}$ mesons in PbPb collisions at $\sqrt{s_{_{\mathrm{NN}}}}=5.02~\mathrm{TeV}$.
description: The first heavy ion collisions measurements of azimuthal anisotropy elliptic ($v_2$) and triangular ($v_3$) Fourier coefficients of $\mathrm{D}^0$ mesons produced in b hadron decays are presented using PbPb collisions at $\sqrt{s_{_{\mathrm{NN}}}}=5.02~\mathrm{TeV}$. The obtained results are directly compared with previously published charm quark anisotropy measured in the same final state. The data were collected with the CMS detector in 2018 with an integrated luminosity of $0.58~\mathrm{nb}^{-1}$. Azimuthal anisotropy is sensitive to the interactions of quarks with the hot and dense medium created in heavy ion collisions. Comparing results for charm quarks, measured by a $\mathrm{D}^0$ meson, to those for the heavier bottom quarks can assist in understanding the mass dependence of these interactions. The results show lower magnitudes of $v_2$ and $v_3$ and weaker dependences on the meson transverse momentum and collision centrality than those found for prompt $\mathrm{D}^0$ mesons. The $v_3$ coefficient of $\mathrm{D}^0$ mesons from b hadron decays is found to be nonzero. The results are compared to various theoretical calculations.

title: "Figure 6 (middle)" of "Higher-order moments of the elliptic flow distribution in PbPb collisions at $\sqrt{s_\mathrm{NN}}$ = 5.02 TeV"

description: The magnitudes of the measured kurtosis $\gamma_2^\textrm{exp}$ and "corrected" kurtosis $\gamma_{2,\textrm{corr}}^\textrm{exp}$ as functions of centrality in PbPb collisions at $\sqrt{s_{NN}}=5.02~\textrm{Te}\textrm{V}$. The measurement is performed with charged particles within the acceptance region.
description: The hydrodynamic flow-like behavior of charged hadrons in high-energy lead-lead collisions is studied through multiparticle correlations. The elliptic anisotropy values based on different orders of multiparticle cumulants, $v_{2}\{2k\}$, are measured up to the tenth order ($k = 5$) as functions of the collision centrality at a nucleon-nucleon center-of-mass energy of $\sqrt{s_{\rm{NN}}}=5.02~\textrm{Te}\textrm{V}$. The data were recorded by the CMS experiment at the LHC and correspond to an integrated luminosity of $0.607~\textrm{nb}^{-1}$. A hierarchy is observed between the coefficients, with $v_{2}\{2\} &gt; v_{2}\{4\} \gtrsim v_{2}\{6\} \gtrsim v_{2}\{8\} \gtrsim v_{2}\{10\}$. Based on these results, centrality-dependent moments for the fluctuation-driven event-by-event $v_{2}$ distribution are determined, including the skewness, kurtosis and, for the first time, superskewness. Assuming a hydrodynamic expansion of the produced medium, these moments directly probe the initial-state geometry in high-energy nucleus-nucleus collisions.

description: The production of $\Upsilon(2S)$ and $\Upsilon(3S)$ mesons in lead-lead ($\text{PbPb}$) and proton-proton ($\text{pp}$) collisions is studied in their dimuon decay channel using the CMS detector at the LHC. The $\Upsilon(3S)$ meson is observed for the first time in \PbPb collisions, with a significance above five standard deviations. The nuclear modification factors, derived from the ratio of yields measured in $\text{PbPb}$ to $\text{pp}$ collisions, are reported for both $\Upsilon(2S)$ and $\Upsilon(3S)$ mesons as functions of $\Upsilon$ meson transverse momentum and $\text{PbPb}$ collision centrality. The suppression is found to be stronger for $\Upsilon(3S)$ mesons compared to $\Upsilon(2S)$ mesons, extending the pattern of sequential suppression of quarkonium states in nuclear collisions previously seen for the $J/\psi$, $\psi(2S)$, $\Upsilon(1S)$ and $\Upsilon(2S)$ mesons. The results provide new constraints on theoretical descriptions of the dynamics of quarkonium states in heavy ion collisions.

title: "Figure 1-0" of "Azimuthal anisotropy of dijet events in PbPb collisions at $\sqrt{s_\mathrm{NN}}$ = 5.02 TeV"

description: The dijet $v_{n}$ data points factorized using different associated hadron pT bins for 0-10 % centrality bin. The data points are corrected for the jet reconstruction bias effects.
description: The path-length dependent parton energy loss within the quark-gluon plasma created in lead-lead collisions at $\sqrt{s_{\mathrm{NN}}} = 5.02$ TeV is studied by determining the azimuthal anisotropies for high-$p_{\mathrm{T}}$ dijets. The anisotropies are expressed as the Fourier expansion coefficients $v_{2}$, $v_{3}$, and $v_{4}$. The data were collected by the CMS experiment in 2018 and correspond to an integral luminosity of 1.7 $\mathrm{nb}^{-1}$. Jet-hadron and hadron-hadron correlations from events with back-to-back dijets are constructed as functions of relative azimuthal angle and pseudorapidity between a jet and a hadron and between two hadrons, respectively. Together, these correlations allow for a determination of the dijet $v_{n}$ values assuming factorization. Restricting the analysis to long-range components of the correlations provides robust suppression of background contributions from fragmentation processes. Positive dijet $v_{2}$ values are found that show a strong centrality dependence, consistent with previous high-$p_{\mathrm{T}}$ hadron and inclusive jet measurements. The dijet $v_{3}$ and $v_{4}$ values are consistent with zero, which is also seen for high-$p_{\mathrm{T}}$ hadron $v_{3}$ values in previous studies.
