title: "Figure 3" of "Probing charm quark dynamics via multiparticle correlations in PbPb collisions at $\sqrt{s_\mathrm{NN}}$ =5.02 TeV"

description: Prompt $D^0+\overline{D}^0$ meson $v_2\{2\}$, $v_2\{4\}$, and $v_2\{4\}/v_2\{2\}$ as a function of centrality from PbPb collisions at $\sqrt{s_{NN}} = 5.02$ TeV.
description: Multiparticle azimuthal correlations of prompt $D^0$ mesons are measured in PbPb collisions at $\sqrt{s_{NN}}=5.02~TeV$. The data, collected using the CMS detector at the LHC in 2018, correspond to an integrated luminosity of $0.58~nb^{-1}$. The second Fourier coefficient of the azimuthal distribution ($v_2$) of $D^0$ mesons as a function of their transverse momentum and event centrality is extracted for the first time using a four-particle cumulant method. Using previously measured two-particle cumulant results, the ratios of $v_2$ values obtained with the four- and two-particle cumulant methods are found to be below unity for prompt $D^0$ mesons. These ratios are also comparable to those of all charged particles in the event. However, hints of deviation are seen in the most central and peripheral collisions. To further investigate the origin of flow fluctuations in the charm sector, these measurements are compared with models implementing different mechanisms of charm quark energy loss in the quark-gluon plasma.

title: "Table 1" of "Measurement of the energy asymmetry in $t\bar{t}j$ production at 13 TeV with the ATLAS experiment and interpretation in the SMEFT framework"

description: Data Measurements and predictions of the energy asymmetry in three bins of the jet angle $\theta_j$. The SM prediction was obtained from simulations of $t\bar{t}j$ events with MadGraph5_aMC@NLO + Pythia 8 at NLO in QCD for $t\bar{t}j$ + PS, including MC statistical and scale uncertainties.
description: A measurement of the energy asymmetry in jet-associated top-quark pair production is presented using $139\,\mathrm{fb}^{-1}$ of data collected by the ATLAS detector at the Large Hadron Collider during $pp$ collisions at $\sqrt{s}=13\,\text{TeV}$. The observable measures the different probability of top and antitop quarks to have the higher energy as a function of the jet scattering angle with respect to the beam axis. The energy asymmetry is measured in the semileptonic $t\bar{t}$ decay channel, and the hadronically decaying top quark must have transverse momentum above $350\,\text{GeV}$. The results are corrected for detector effects to particle level in three bins of the scattering angle of the associated jet. The measurement agrees with the SM prediction at next-to-leading-order accuracy in quantum chromodynamics in all three bins. In the bin with the largest expected asymmetry, where the jet is emitted perpendicular to the beam, the energy asymmetry is measured to be $-0.043\pm0.020$, in agreement with the SM prediction of $-0.037\pm0.003$. Interpreting this result in the framework of the Standard Model effective field theory (SMEFT), it is shown that the energy asymmetry is sensitive to the top-quark chirality in four-quark operators and is therefore a valuable new observable in global SMEFT fits.

title: "Table 3" of "Measurement of the energy asymmetry in $t\bar{t}j$ production at 13 TeV with the ATLAS experiment and interpretation in the SMEFT framework"

description: The effects on the energy asymmetry of $1\sigma$ variations in its influencing nuisance parameters for the three $\theta_j$ bins. These are extracted from the samples of the posterior distribution with $\sigma_i^{(j)} = c_{ij}/\sqrt{c_{jj}}$ being the estimated shift of bin $i$ in conjunction with a shift $\Delta\theta_j$ of nuisance parameter $j$. The data statistical (Data stat.) uncertainty is obtained from running the unfolding with all nuisance parameters being fixed to their post-marginalised values, the MC statistical uncertainty on the response matrix ($t\bar{t}$ response MC stat.) is evaluated using a bootstrapping method from the covariance matrix of the ensemble of repeated unfolding results with varied response matrices. The $\gamma$ variations denote the statistical uncertainties of the background predictions in the corresponding bin of the $\Delta E$ vs $\theta_{j}$ distribution. The numbers appended to the $W$+jets PDF variations denote the corresponding NNPDF3.0 PDF sets.
