The $\\Xi_c^+$ baryon is reconstructed via the $\\Xi_c^+ \\rightarrow \\Xi^-\\pi^+\\pi^+$ decay channel in the range $4 &lt;~ p_{\\rm T} &lt;~ 12$ GeV/$c$, while the $\\Xi_c^0$ baryon is reconstructed via both the $\\Xi_c^0 \\rightarrow \\Xi^-\\pi^+$ and $\\Xi_c^0 \\rightarrow \\Xi^-e^+\\nu_e$ decay channels in the range $2 &lt;~ p_{\\rm T} &lt;~ 12$ GeV/$c$. The baryon-to-meson ($\\Xi_c^{0,+}/D^0$) and the baryon-to-baryon ($\\Xi_c^{0,+}/\\Lambda_c^+$) production yield ratios show no significant dependence on multiplicity. In addition, the observed yield ratios are not described by theoretical predictions that model charm-quark fragmentation based on measurements at $e^+e^-$ and $e^-$p colliders, indicating differences in the charm-baryon production mechanism in pp collisions. A comparison with different event generators and tunings, including different modelling of the hadronisation process, is also discussed. Moreover, the branching-fraction ratio of BR($\\Xi_c^0 \\rightarrow \\Xi^-e^+\\nu_e$)/BR($\\Xi_c^0 \\rightarrow \\Xi^-\\pi^+$) is measured as 0.825 $\\pm$ 0.094 (stat.) $\\pm$ 0.081 (syst.). This value supersedes the previous ALICE measurement, improving the statistical precision by a factor of 1.6.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.166317.v1/t1","@type":"Dataset","description":"$p_{\\rm T}$-differential per-event yield of prompt $\\Xi_c^0$ baryons measured in the different multiplicity classes.","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.166317.v1/t2","@type":"Dataset","description":"$p_{\\rm T}$-differential per-event yield of prompt $\\Xi_c^+$ baryons measured in the different multiplicity classes.","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.166317.v1/t3","@type":"Dataset","description":"Ratio between the prompt $\\Xi_c^0$ baryons in a multiplicity class to the multiplicity-integrated (INEL $&gt;$ 0) class.","name":"Table 3"},{"@id":"https://doi.org/10.17182/hepdata.166317.v1/t4","@type":"Dataset","description":"Ratio between the prompt $\\Xi_c^+$ baryons in a multiplicity class to the multiplicity-integrated (INEL $&gt;$ 0) class.","name":"Table 4"},{"@id":"https://doi.org/10.17182/hepdata.166317.v1/t5","@type":"Dataset","description":"The prompt production yield ratios between $\\Xi_c^0$ and $\\rm {D}^0$ measured in the same multiplicity classes.","name":"Table 5"},{"@id":"https://doi.org/10.17182/hepdata.166317.v1/t6","@type":"Dataset","description":"The prompt production yield ratios between $\\Xi_c^+$ and $\\rm {D}^0$ measured in the same multiplicity classes.","name":"Table 6"},{"@id":"https://doi.org/10.17182/hepdata.166317.v1/t7","@type":"Dataset","description":"The prompt production yield ratios between $\\Xi_c^0$ and $\\Lambda_c^+$ measured in the same multiplicity classes.","name":"Table 7"},{"@id":"https://doi.org/10.17182/hepdata.166317.v1/t8","@type":"Dataset","description":"The prompt production yield ratios between $\\Xi_c^+$ and $\\Lambda_c^+$ measured in the same multiplicity classes.","name":"Table 8"},{"@id":"https://doi.org/10.17182/hepdata.166317.v1/t9","@type":"Dataset","description":"The branching-fraction ratio of BR($\\Xi_c^0 \\rightarrow \\Xi^-e^+\\nu_e$)/BR($\\Xi_c^0 \\rightarrow \\Xi^-\\pi^+$)","name":"Table 9"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins2960135?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/166317"}],"inLanguage":"en","name":"Multiplicity dependence of $\u039e_c^+$ and $\u039e_c^0$ production in pp collisions at $\\sqrt{s} = 13$ TeV","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins2960135?version=1","version":1}
