This is the first measurement of $\\Sigma_{\\rm c}^{0,++}$ production in hadronic collisions. Assuming the same production yield for the three $\\Sigma_{\\rm c}^{0,+,++}$ isospin states, the baryon-to-meson cross section ratios $\\Sigma_{\\rm c}^{0,+,++}/{\\rm D}^{0}$ and $\\Lambda_{\\rm c}^{+}/{\\rm D}^{0}$ are calculated in the transverse momentum ($p_{\\rm T}$) intervals $2 < p_{\\rm T} < 12$ GeV/$c$ and $1 < p_{\\rm T} < 24$ GeV/$c$. Values significantly larger than in e$^{+}$e$^{-}$ collisions are observed, indicating for the first time that baryon enhancement in hadronic collisions also extends to the $\\Sigma_{\\rm c}$. The feed-down contribution to $\\Lambda_{\\rm c}^{+}$ production from $\\Sigma_{\\rm c}^{0,+,++}$ is also reported and is found to be larger than in e$^{+}$e$^{-}$ collisions. The data are compared with predictions from event generators and other phenomenological models, providing a sensitive test of the different charm-hadronisation mechanisms implemented in the models.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.127976.v1/t1","@type":"Dataset","description":"$p_\\mathrm{T}$-differential cross section of prompt $D^0$ in pp collisions at $\\sqrt{s}$ = 13 TeV","name":"Figure 1 Right D0"},{"@id":"https://doi.org/10.17182/hepdata.127976.v1/t2","@type":"Dataset","description":"$p_\\mathrm{T}$-differential cross section of prompt $\\Lambda_c^+$ in pp collisions at $\\sqrt{s}$ = 13 TeV","name":"Figure 1 Right Lc"},{"@id":"https://doi.org/10.17182/hepdata.127976.v1/t3","@type":"Dataset","description":"$p_\\mathrm{T}$-differential cross section of prompt $\\Sigma_c^{0,++}$ in pp collisions at $\\sqrt{s}$ = 13 TeV","name":"Figure 1 Right Sc"},{"@id":"https://doi.org/10.17182/hepdata.127976.v1/t4","@type":"Dataset","description":"$3/2 \\cdot p_\\mathrm{T}$-differential cross section of prompt $\\Lambda_c^+$ from $\\Sigma_c^{++}$ in pp collisions at $\\sqrt{s}$ = 13 TeV","name":"Lc from Sc"},{"@id":"https://doi.org/10.17182/hepdata.127976.v1/t5","@type":"Dataset","description":"Prompt-charm-hadron cross-section ratio $\\Lambda_c^+/D^0$ in pp collisions at $\\sqrt{s} = 13$ TeV","name":"Figure 2 Left"},{"@id":"https://doi.org/10.17182/hepdata.127976.v1/t6","@type":"Dataset","description":"Prompt-charm-hadron cross-section ratio $\\Sigma_c^{0,+,++}/D^0$ in pp collisions at $\\sqrt{s} = 13$ TeV","name":"Figure 2 Middle"},{"@id":"https://doi.org/10.17182/hepdata.127976.v1/t7","@type":"Dataset","description":"Prompt-charm-hadron cross-section ratio $\\Lambda_c^+ \\leftarrow \\Sigma_c^{0,+,++}/\\Lambda_c^+$ in pp collisions at $\\sqrt{s} = 13$ TeV","name":"Figure 2 Right"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1868463?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/127976"}],"inLanguage":"en","name":"Measurement of prompt D$^{0}$, $\\Lambda_{c}^{+}$, and $\\Sigma_{c}^{0,++}$(2455) 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/ins1868463?version=1","version":1}
