The $p_{\\rm T}$-differential cross section of $\\omega$ meson production in pp collisions at $\\sqrt{s}=13$ TeV at midrapidity ($|y|<0.5$) was measured with the ALICE detector at the LHC, covering an unprecedented transverse-momentum range of $1.6<p_{\\rm T}<50$ GeV/c. The meson is reconstructed via the $\\omega\\rightarrow\\pi^+\\pi^-\\pi^0$ decay channel. The results are compared with various theoretical calculations: PYTHIA8.2 with the Monash 2013 tune overestimates the data by up to 50\\%, whereas good agreement is observed with Next-to-Leading Order (NLO) calculations incorporating $\\omega$ fragmentation using a broken SU(3) model. The $\\omega/\\pi^0$ ratio is presented and compared with theoretical calculations and the available measurements at lower collision energies. The presented data triples the $p_{\\rm T}$ ranges of previously available measurements. A constant ratio of $C^{\\omega/\\pi^0}=0.578\\pm0.006~\\text{(stat.)}\\pm 0.013~\\text{(syst.)}$ is found above a transverse momentum of $4$ GeV/c, which is in agreement with previous findings at lower collision energies within the systematic and statistical uncertainties.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.157865.v1/t1","@type":"Dataset","description":"Invariant differential cross section of OMEGA mesons produced in inelastic pp collisions at center-of-mass energy 13 TeV, the uncertainty of...","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.157865.v1/t2","@type":"Dataset","description":"The measured ratio of cross sections for inclusive OMEGA to PI0 production at a centre-of-mass energy of 13 TeV.","name":"Table 2"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins2848263?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/157865"}],"inLanguage":"en","name":"Measurement of $\\omega$ meson 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/ins2848263?version=1","version":1}
