For $p_\\mathrm{T}>10~\\mathrm{GeV}/c$, the measured $\\mathrm{D_s^+}$-meson nuclear modification factor $R_\\mathrm{AA}$ is consistent with the one of non-strange D mesons within uncertainties, while at lower $p_\\mathrm{T}$ a hint for a $\\mathrm{D_s^+}$-meson $R_\\mathrm{AA}$ larger than that of non-strange D mesons is seen. The enhanced production of $\\mathrm{D_s^+}$ relative to non-strange D mesons is also studied by comparing the $p_\\mathrm{T}$-dependent $\\mathrm{D_s^+}/\\mathrm{D^0}$ production yield ratios in Pb-Pb and in pp collisions. The $\\mathrm{D_s^+}/\\mathrm{D^0}$ ratio measured in Pb-Pb collisions is found to be on average higher than that in pp collisions in the transverse-momentum interval $2<p_\\mathrm{T}<8~\\mathrm{GeV}/c$ with a significance of $2.3\\sigma$ and $2.4\\sigma$ for the 0-10% and 30-50% centrality intervals, respectively. The azimuthal anisotropy coefficient $v_2$ of prompt $\\mathrm{D_s^+}$ mesons was measured in Pb-Pb collisions in the 30-50% centrality interval and it is found to be compatible with that of non-strange D mesons. The main features of the measured $R_\\mathrm{AA}$, $\\mathrm{D_s^+}/\\mathrm{D^0}$ ratio, and $v_2$ as a function of $p_\\mathrm{T}$ are described by theoretical calculations of charm-quark transport in a hydrodynamically expanding quark-gluon plasma including hadronisation via charm-quark recombination with light quarks from the medium. The $p_\\mathrm{T}$-integrated production yield of $\\mathrm{D_s^+}$ mesons is compatible with the prediction of the statistical hadronisation model.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.127980.v2/t1","@type":"Dataset","description":"$p_\\mathrm{T}$-differential production yield of prompt $\\mathrm{D_s^+}$ mesons in the 0-10% centrality class in Pb-Pb collisions at $\\sqrt{{s_\\mathrm{NN}}}=5.02~\\mathrm{{TeV}}$ in the rapidity...","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.127980.v2/t2","@type":"Dataset","description":"$p_\\mathrm{T}$-differential production yield of prompt $\\mathrm{D_s^+}$ mesons in the 30-50% centrality class in Pb-Pb collisions at $\\sqrt{{s_\\mathrm{NN}}}=5.02~\\mathrm{{TeV}}$ in the rapidity...","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.127980.v2/t3","@type":"Dataset","description":"$p_\\mathrm{T}$-differential nuclear modification factor $R_\\mathrm{AA}$ of prompt $\\mathrm{D_s^+}$ mesons in the 0-10% centrality class in Pb-Pb collisions at $\\sqrt{{s_\\mathrm{NN}}}=5.02~\\mathrm{{TeV}}$ in...","name":"Table 3"},{"@id":"https://doi.org/10.17182/hepdata.127980.v2/t4","@type":"Dataset","description":"$p_\\mathrm{T}$-differential nuclear modification factor $R_\\mathrm{AA}$ of prompt $\\mathrm{D_s^+}$ mesons in the 30-50% centrality class in Pb-Pb collisions at $\\sqrt{{s_\\mathrm{NN}}}=5.02~\\mathrm{{TeV}}$ in...","name":"Table 4"},{"@id":"https://doi.org/10.17182/hepdata.127980.v2/t5","@type":"Dataset","description":"$p_\\mathrm{{T}}$-differential production ratios of prompt $\\mathrm{D}_s^+/\\mathrm{D}^0$ mesons in the 0-10% centrality class in Pb-Pb collisions at $\\sqrt{{s_\\mathrm{NN}}}=5.02~\\mathrm{{TeV}}$ in the rapidity...","name":"Table 5"},{"@id":"https://doi.org/10.17182/hepdata.127980.v2/t6","@type":"Dataset","description":"$p_\\mathrm{{T}}$-differential production ratios of prompt $\\mathrm{D}_s^+/\\mathrm{D}^0$ mesons in the 30-50% centrality class in Pb-Pb collisions at $\\sqrt{{s_\\mathrm{NN}}}=5.02~\\mathrm{{TeV}}$ in the rapidity...","name":"Table 6"},{"@id":"https://doi.org/10.17182/hepdata.127980.v2/t7","@type":"Dataset","description":"$p_\\mathrm{{T}}$-differential prompt $\\mathrm{D}_s^+/\\mathrm{D}^0$ ratios in Pb-Pb collisions in the 0-10% centrality class at $\\sqrt{s_\\mathrm{NN}}=5.02~\\mathrm{TeV}$ divided by those in pp collisions...","name":"Table 7"},{"@id":"https://doi.org/10.17182/hepdata.127980.v2/t8","@type":"Dataset","description":"$p_\\mathrm{{T}}$-differential prompt $\\mathrm{D}_s^+/\\mathrm{D}^0$ ratios in Pb-Pb collisions in the 30-50% centrality class at $\\sqrt{s_\\mathrm{NN}}=5.02~\\mathrm{TeV}$ divided by those in pp collisions...","name":"Table 8"},{"@id":"https://doi.org/10.17182/hepdata.127980.v2/t9","@type":"Dataset","description":"$p_\\mathrm{T}$-differential elliptic flow coefficient $v_2$ of prompt $\\mathrm{D_s^+}$ mesons in the 30-50% centrality class in Pb-Pb collisions at $\\sqrt{{s_\\mathrm{NN}}}=5.02~\\mathrm{{TeV}}$.","name":"Table 9"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1946931?version=2"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/127980"}],"inLanguage":"en","name":"Measurement of prompt $\\rm{D_{s}^{+}}$-meson production and azimuthal anisotropy in Pb-Pb collisions at $\\sqrt{s_{\\rm NN}} = 5.02$ TeV","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins1946931?version=2","version":2}
