ALICE. The transverse momentum ($p_\\mathrm{T}$) differential production cross section of the promptly produced charm-strange baryon $\\Xi_\\mathrm{c}^0$ (and its charge conjugate $\\overline{\\Xi_\\mathrm{c}^0}$) is measured at midrapidity via its hadronic decay into ${\\pi^{+}}\\Xi^{-}$ in p$-$Pb collisions at a centre-of-mass energy per nucleon$-$nucleon collision $\\sqrt{s_\\mathrm{NN}}= 5.02$ TeV with the ALICE detector at the LHC. The $\\Xi_\\mathrm{c}^0$ nuclear modification factor ($R_\\mathrm{pPb}$), calculated from the cross sections in pp and p$-$Pb collisions, is presented and compared with the $R_\\mathrm{pPb}$ of $\\mathrm{\\Lambda_c^+}$ baryons. The ratios between the $p_\\mathrm{T}$-differential production cross section of $\\Xi_\\mathrm{c}^0$ baryons and those of $\\mathrm{D^0}$ mesons and $\\mathrm{\\Lambda_c^+}$ baryons are also reported and compared with results at forward and backward rapidity from the LHCb Collaboration. The measurements of the production cross section of prompt $\\Xi^0_\\mathrm{c}$ baryons are compared with a model based on perturbative QCD calculations of charm-quark production cross sections, which includes only cold nuclear matter effects in p$-$Pb collisions, and underestimates the measurement by a factor of about 50.  This discrepancy is reduced when the data is compared with a model that includes string formation beyond leading-colour approximation or in which hadronisation is implemented via quark coalescence. The $p_\\mathrm{T}$-integrated cross section of prompt $\\Xi^0_\\mathrm{c}$-baryon production at midrapidity extrapolated down to $p_\\mathrm{T}$ = 0 is also reported. These measurements offer insights and constraints for theoretical calculations of the hadronisation process. Additionally, they provide inputs for the calculation of the charm production cross section in p$-$Pb collisions at midrapidity.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.155330.v1/t1","@type":"Dataset","description":"Prompt $\\Xi_\\mathrm{c}^0$ productions cross-section as a function of $p_\\mathrm{T}$ in p\u2013Pb collisions at $\\sqrt{s_\\mathrm{NN}} = 5.02$ TeV.","name":"Figure 3 left"},{"@id":"https://doi.org/10.17182/hepdata.155330.v1/t2","@type":"Dataset","description":"$\\Xi_\\mathrm{c}^0~R_\\mathrm{pPb}$ as a function of $p_\\mathrm{T}$ in p\u2013Pb collisions at $\\sqrt{s_\\mathrm{NN}} = 5.02$ TeV.","name":"Figure 4"},{"@id":"https://doi.org/10.17182/hepdata.155330.v1/t3","@type":"Dataset","description":"$\\Xi_\\mathrm{c}^0/\\mathrm{D}^0$ ratio as a function of $p_\\mathrm{T}$ in p\u2013Pb collisions at $\\sqrt{s_\\mathrm{NN}} = 5.02$ TeV.","name":"Figure 5 left"},{"@id":"https://doi.org/10.17182/hepdata.155330.v1/t4","@type":"Dataset","description":"$\\Xi_\\mathrm{c}^0/\\Lambda_c^+$ ratio as a function of $p_\\mathrm{T}$ in p\u2013Pb collisions at $\\sqrt{s_\\mathrm{NN}} = 5.02$ TeV.","name":"Figure 5 right"},{"@id":"https://doi.org/10.17182/hepdata.155330.v1/t5","@type":"Dataset","description":"Prompt $\\Xi_\\mathrm{c}^0$ cross-section integrated in the $2 < p_\\mathrm{T} < 12$ GeV/$c$ interval measured in p\u2013Pb collisions at $\\sqrt{s_\\mathrm{NN}} =...","name":"Visible cross section"},{"@id":"https://doi.org/10.17182/hepdata.155330.v1/t6","@type":"Dataset","description":"Prompt $\\Xi_\\mathrm{c}^0$ $p_\\mathrm{T}$-integrated cross-section in the $p_\\mathrm{T}>0$ interval measured in p\u2013Pb collisions at $\\sqrt{s_\\mathrm{NN}} = 5.02$ TeV.","name":"Integrated cross section"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins2789570?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/155330"}],"inLanguage":"en","name":"Measurement of the production cross section of prompt $\\Xi^0_{\\rm c}$ baryons in p$-$Pb collisions at $\\sqrt{s_{\\mathrm{NN}}}~=~5.02$ TeV","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins2789570?version=1","version":1}
