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.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.111310.v1/t1","@type":"Dataset","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 $p_T$ from PbPb collisions at $\\sqrt{s_{NN}} = 5.02$ TeV.","name":"Figure 2a"},{"@id":"https://doi.org/10.17182/hepdata.111310.v1/t2","@type":"Dataset","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 $p_T$ from PbPb collisions at $\\sqrt{s_{NN}} = 5.02$ TeV.","name":"Figure 2b"},{"@id":"https://doi.org/10.17182/hepdata.111310.v1/t3","@type":"Dataset","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.","name":"Figure 3"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1996546?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/111310"}],"inLanguage":"en","name":"Probing charm quark dynamics via multiparticle correlations in PbPb collisions at $\\sqrt{s_\\mathrm{NN}}$ =5.02 TeV","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins1996546?version=1","version":1}
