The measurement is performed in the D$^0$ meson $p_\\mathrm{t}$ range of 2-100 GeV and in the rapidity range of $|y| < $1. The pp (PbPb) dataset used for this analysis corresponds to an integrated luminosity of 27.4 pb$^{-1}$ (530 $\\mu$b$^{-1}$). The measured D$^0$ meson $p_\\mathrm{t}$ spectrum in pp collisions is well described by perturbative QCD calculations. The nuclear modification factor, comparing D$^0$ meson yields in PbPb and pp collisions, was extracted for both minimum-bias and the 10% most central PbPb interactions. For central events, the D$^0$ meson yield in the PbPb collisions is suppressed by a factor of 5-6 compared to the pp reference in the $p_\\mathrm{t}$ range of 6-10 GeV. For D$^0$ mesons in the high-$p_\\mathrm{t}$ range of 60-100 GeV, a significantly smaller suppression is observed. The results are also compared to theoretical calculations.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.79053.v1/t1","@type":"Dataset","description":"Nuclear modification factor of $(D^{0}+\\overline{D}\\hspace{.01cm}^{0})/2$ as a function of $p_{T}$ in the centrality range $0-100\\%$ and $0-10\\%$.","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.79053.v1/t2","@type":"Dataset","description":"The $p_{T}$-differential production cross section of $(D^{0}+\\overline{D}\\hspace{.01cm}^{0})/2$ in pp collisions.","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.79053.v1/t3","@type":"Dataset","description":"The $p_{T}$-differential production yields of $(D^{0}+\\overline{D}\\hspace{.01cm}^{0})/2$ divided by the nuclear overlap functions $T_{AA}$ for PbPb collisions in the $0-100\\%$ and...","name":"Table 3"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1616207?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/79053"}],"inLanguage":"en","name":"Nuclear modification factor of D0 mesons in PbPb collisions at sqrt(s[NN]) = 5.02 TeV","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins1616207?version=1","version":1}
