The D$^0$ mesons and their charge conjugates are reconstructed from the hadronic decay D$^0\\to \\mathrm K^{-}\\pi^{+}$. Jets are reconstructed from D$^0$-meson candidates and charged particles using the anti-$k_\\mathrm{T}$ algorithm with jet resolution parameter $R~=~0.3$, in the jet transverse momentum ($p_{\\mathrm{T}}$) range 5$~< p_\\mathrm{T}^\\mathrm{ch\\ jet}<$ 50 GeV/$c$ and pseudorapidity $|\\eta^\\mathrm{ch~jet}| < 0.6$. A hint of reduced suppression in the charm-jet $R_{\\mathrm{AA}}$ is observed in comparison to inclusive jets in central Pb$-$Pb collisions with a significance of about 2$\\sigma$ in 20 $~<~p_\\mathrm{T}^\\mathrm{ch\\ jet}~<~$ 50 GeV/$c$, suggesting the in-medium energy loss to depend on both the difference between quark and gluon coupling strength (Casimir colour-charge effect) and quark mass (dead-cone effect). The data are compared with model calculations that include mass effects in the in-medium energy loss. Among these, LIDO provides the best description of the data, highlighting the role of mass effects in interpreting the results.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.168854.v1/t1","@type":"Dataset","description":"$p_{\\mathrm{T,ch\\ jet}}$-differential yields of charm jets tagged with $\\mathrm{D^{0}}$ mesons for $R=0.3$, in Pb$-$Pb and pp collisions at $\\sqrt{s}=5.02$ TeV.","name":"$\\mathrm{D^{0}}$ jets in Pb$-$Pb and pp at 5.02 TeV"},{"@id":"https://doi.org/10.17182/hepdata.168854.v1/t2","@type":"Dataset","description":"$p_{\\mathrm{T,ch\\ jet}}$-differential nuclear modification factor of charm jets tagged with $\\mathrm{D^{0}}$ mesons for $R=0.3$ in Pb-Pb collisions at $\\sqrt{s}=5.02$ TeV.","name":"$\\mathrm{D^{0}}$-jet $R_{\\mathrm{AA}}$"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins2829716?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/168854"}],"inLanguage":"en","name":"Investigating charm quark energy loss in medium with the nuclear modification factor of D$^0$-tagged jets","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins2829716?version=1","version":1}
