Neutral pion and $\\eta$ meson production in the transverse momentum range 1 $< p_{\\rm T} <$ 20 GeV/$c$ have been measured at midrapidity by the ALICE experiment at the Large Hadron Collider (LHC) in central and semi-central Pb-Pb collisions at $\\sqrt{s_{\\rm NN}}$ = 2.76 TeV. These results extend the $p_{\\rm T}$ reach of the previous ALICE PI0 measurements from 12 GeV/$c$ to 20 GeV/$c$ and present the first measurement of the ETA meson in heavy-ion collisions at the LHC. The $\\eta$ to $\\pi^{0}$ ratio is similar for the two centralities and reaches a plateau value of 0.457 $\\pm$ 0.013$^{stat}$ $\\pm$ 0.018$^{syst}$. A suppression of the same magnitude for $\\pi^{0}$ and $\\eta$ meson production is observed in Pb-Pb collisions with respect to their production in pp collisions scaled by the number of binary nucleon-nucleon collisions. For both mesons, the nuclear modification factor $R_{\\rm AA}$ reaches a minimum at $p_{\\rm T} \\approx $ 7 GeV/$c$ and then increases with transverse momentum. The measurements show a stronger suppression with respect to what was observed at lower center-of-mass energies in the $p_{\\rm T}$ range 6 $< p_{\\rm T} <$ 10 GeV/$c$. The results are compared with statistical hadronization models at low-$p_{\\rm T}$ and with NLO pQCD jet quenching predictions at high-$p_{\\rm T}$.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.83964.v1/t1","@type":"Dataset","description":"Invariant yields of the $\\pi^{0}$ meson in the centrality class 0-10% in Pb-Pb collisions at sqrt{s_NN} = 2.76 TeV at...","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.83964.v1/t2","@type":"Dataset","description":"Invariant yields of the $\\pi^{0}$ meson in the centrality class 20-50% in Pb-Pb collisions at sqrt{s_NN} = 2.76 TeV at...","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.83964.v1/t3","@type":"Dataset","description":"Invariant yields of the $\\eta$ meson in the centrality class 0-10% in Pb-Pb collisions at sqrt{s_NN} = 2.76 TeV at...","name":"Table 3"},{"@id":"https://doi.org/10.17182/hepdata.83964.v1/t4","@type":"Dataset","description":"Invariant yields of the $\\eta$ meson in the centrality class 20-50% in Pb-Pb collisions at sqrt{s_NN} = 2.76 TeV at...","name":"Table 4"},{"@id":"https://doi.org/10.17182/hepdata.83964.v1/t5","@type":"Dataset","description":"Nuclear modification factor R_AA of $\\pi^{0}$ produced in 0-10% central Pb-Pb collisions at sqrt{s_NN} = 2.76 TeV at mid-rapidity, T_AA...","name":"Table 5"},{"@id":"https://doi.org/10.17182/hepdata.83964.v1/t6","@type":"Dataset","description":"Nuclear modification factor R_AA of $\\pi^{0}$ produced in 20-50% central Pb-Pb collisions at sqrt{s_NN} = 2.76 TeV at mid-rapidity, T_AA...","name":"Table 6"},{"@id":"https://doi.org/10.17182/hepdata.83964.v1/t7","@type":"Dataset","description":"Nuclear modification factor R_AA of $\\eta$ produced in 0-10% central Pb-Pb collisions at sqrt{s_NN} = 2.76 TeV at mid-rapidity, T_AA...","name":"Table 7"},{"@id":"https://doi.org/10.17182/hepdata.83964.v1/t8","@type":"Dataset","description":"Nuclear modification factor R_AA of $\\eta$ produced in 20-50% central Pb-Pb collisions at sqrt{s_NN} = 2.76 TeV at mid-rapidity, T_AA...","name":"Table 8"},{"@id":"https://doi.org/10.17182/hepdata.83964.v1/t9","@type":"Dataset","description":"Ratio of the $\\eta$ to $\\pi^{0}$ invariant yields in 0-10% central Pb-Pb collisions at sqrt{s_NN} = 2.76 TeV at mid-rapidity.","name":"Table 9"},{"@id":"https://doi.org/10.17182/hepdata.83964.v1/t10","@type":"Dataset","description":"Ratio of the $\\eta$ to $\\pi^{0}$ invariant yields in 20-50% central Pb-Pb collisions at sqrt{s_NN} = 2.76 TeV at mid-rapidity.","name":"Table 10"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1662651?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/83964"}],"inLanguage":"en","name":"Neutral pion and $\\eta$ meson production at mid-rapidity in Pb-Pb collisions at $\\sqrt{s_{NN}}$ = 2.76 TeV","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins1662651?version=1","version":1}
