The transverse momentum ($p_{\\rm T}$) differential cross section multiplied by the branching ratio is presented in the interval $2<p_{\\rm T}<12~{\\rm GeV}/c$. The $p_{\\rm T}$ dependence of the $\\rm \\Omega_c^0$-baryon production relative to the prompt $\\rm D^0$-meson and to the prompt $\\rm \\Xi_c^0$-baryon production is compared to various models that take different hadronisation mechanisms into consideration. In the measured $p_{\\rm T}$ interval, the ratio of the $p_{\\rm T}$-integrated cross sections of $\\rm \\Omega_c^0$ and prompt $\\rm \\Lambda_c^+$ baryons multiplied by the $\\rm \\Omega^-\\pi^+$ branching ratio is found to be larger by a factor of about 20 with a significance of about 4$\\sigma$ when compared to $\\rm e^+e^-$ collisions.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.136180.v1/t1","@type":"Dataset","description":"The $p_{\\rm T}$-differential production cross section of inclusive $\\rm \\Omega_c^0$ baryons multiplied by the branching ratio into $\\rm \\Omega^-\\pi^+$ for...","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.136180.v1/t2","@type":"Dataset","description":"$\\rm BR(\\Omega_{c}^{0} \\rightarrow \\Omega^{-}\\pi^{+}) \\times {\\it \\sigma}(\\Omega_{c}^{0})/{\\it \\sigma}(D^{0})$ as a function of $p_{\\rm T}$ in pp collisions at $\\sqrt{s}=13$ TeV...","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.136180.v1/t3","@type":"Dataset","description":"$\\rm BR(\\Omega_{c}^{0} \\rightarrow \\Omega^{-}\\pi^{+}) \\times {\\it \\sigma}(\\Omega_{c}^{0})/{\\it \\sigma}(\\Xi_c^0)$ as a function of $p_{\\rm T}$ in pp collisions at $\\sqrt{s}=13$ TeV...","name":"Table 3"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins2088206?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/136180"}],"inLanguage":"en","name":"First measurement of $\\rm \\Omega_c^0$ 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/ins2088206?version=1","version":1}
