An invariant differential cross section measurement of inclusive $\\pi^{0}$ and $\\eta$ meson production at mid-rapidity in pp collisions at $\\sqrt{s}=8$~TeV was carried out by the ALICE experiment at the LHC. The spectra of $\\pi^{0}$ and $\\eta$ mesons are measured in transverse momentum ranges of $0.3<p_{\\rm T}<35$~GeV/$c$ and $0.5<p_{\\rm T}<35$~GeV/$c$, respectively. Next-to-leading order perturbative QCD calculations using fragmentation functions DSS14 for the $\\pi^{0}$ and AESSS for the $\\eta$ overestimate the cross sections of both neutral mesons, although such calculations agree with the measured $\\eta/\\pi^{0}$ ratio within uncertainties. The results are also compared with PYTHIA~8.2 predictions for which the Monash~2013 tune yields the best agreement with the measured neutral meson spectra. The measurements confirm a universal behavior of the $\\eta/\\pi^{0}$ ratio seen for NA27, PHENIX and ALICE data for pp collisions from $\\sqrt{s}=27.5$~GeV to $\\sqrt{s}=8$~TeV within experimental uncertainties. A relation between the $\\pi^{0}$ and $\\eta$ production cross sections for pp collisions at $\\sqrt{s}=8$~TeV is given by \\mT scaling for $p_{\\rm T}>3.5$~GeV/$c$. However, a deviation from this empirical scaling rule is observed for transverse momenta below $p_{\\rm T}<3.5$~GeV/$c$ in the $\\eta/\\pi^{0}$ ratio with a significance of $6.2\\sigma$.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.79044.v2/t1","@type":"Dataset","description":"Invariant differential cross section of $\\pi^0$ produced in inelastic pp collisions at center of mass energy 8 TeV, the uncertainty...","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.79044.v2/t2","@type":"Dataset","description":"Invariant differential cross section of $\\eta$ produced in inelastic pp collisions at center of mass energy 8 TeV, the uncertainty...","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.79044.v2/t3","@type":"Dataset","description":"Integrated yields of $\\pi^{0}$ mesons produced in inelastic pp collisions at center of mass energies of 2.76 and 8 TeV....","name":"Table 3"},{"@id":"https://doi.org/10.17182/hepdata.79044.v2/t4","@type":"Dataset","description":"Integrated yields of $\\eta$ mesons produced in inelastic pp collisions at center of mass energies of 2.76 and 8 TeV....","name":"Table 4"},{"@id":"https://doi.org/10.17182/hepdata.79044.v2/t5","@type":"Dataset","description":"Integrated $\\eta$/$\\pi^{0}$ ratio produced in inelastic pp collisions at center of mass energies of 2.76 and 8 TeV.","name":"Table 5"},{"@id":"https://doi.org/10.17182/hepdata.79044.v2/t6","@type":"Dataset","description":"Mean transverse momenta $\\langle p_\\text{T}\\rangle$ of $\\pi^{0}$ mesons produced in inelastic pp collisions at center of mass energies of 2.76...","name":"Table 6"},{"@id":"https://doi.org/10.17182/hepdata.79044.v2/t7","@type":"Dataset","description":"Mean transverse momenta $\\langle p_\\text{T}\\rangle$ of $\\eta$ mesons produced in inelastic pp collisions at center of mass energies of 2.76...","name":"Table 7"},{"@id":"https://doi.org/10.17182/hepdata.79044.v2/t8","@type":"Dataset","description":"The measured ratio of cross sections for inclusive $\\eta$ to $\\pi^{0}$ production at a center of mass energy of 8...","name":"Table 8"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1620477?version=2"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/79044"}],"inLanguage":"en","name":"$\\pi^0$ and $\\eta$ meson production in proton-proton collisions at $\\sqrt{s}=8$ TeV","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins1620477?version=2","version":2}
