The azimuthal anisotropy coefficients $v_2$ and $v_4$ of $\\pi^0$ and $\\eta$ mesons are measured in Au+Au collisions at $\\sqrt{s_NN}$=200 GeV, as a function of transverse momentum $p_T$ (1-14 GeV/c) and centrality. The extracted $v_2$ coefficients are found to be consistent between the two meson species over the measured $p_T$ range. The ratio of $v_4/v_2^2$ for $\\pi^0$ mesons is found to be independent of $p_T$ for 1-9 GeV/$c$, implying a lack of sensitivity of the ratio to the change of underlying physics with $p_T$. Furthermore, the ratio of $v_4/v_2^2$ is systematically larger in central collisions, which may reflect the combined effects of fluctuations in the initial collision geometry and finite viscosity in the evolving medium.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.96550.v1/t1","@type":"Dataset","description":"$\\eta$ meson $v_2, 0-20\\%$ centrality","name":"Figure 7-1"},{"@id":"https://doi.org/10.17182/hepdata.96550.v1/t2","@type":"Dataset","description":"$\\eta$ meson $v_2, 20-60\\%$ centrality","name":"Figure 7-2"},{"@id":"https://doi.org/10.17182/hepdata.96550.v1/t3","@type":"Dataset","description":"$\\pi^0$ meson $v_4, 0-20\\%$ centrality","name":"Figure 8-1"},{"@id":"https://doi.org/10.17182/hepdata.96550.v1/t4","@type":"Dataset","description":"$\\pi^0$ meson $v_4, 20-40\\%$ centrality","name":"Figure 8-2"},{"@id":"https://doi.org/10.17182/hepdata.96550.v1/t5","@type":"Dataset","description":"$\\pi^0$ meson $v_4, 40-60\\%$ centrality","name":"Figure 8-3"},{"@id":"https://doi.org/10.17182/hepdata.96550.v1/t6","@type":"Dataset","description":"$\\pi^0$ meson $v_4, 20-60\\%$ centrality","name":"Figure 8-4"},{"@id":"https://doi.org/10.17182/hepdata.96550.v1/t7","@type":"Dataset","description":"$\\pi^0$ meson $v_4/v_2^2, 0-20\\%$ centrality","name":"Figure 9-1"},{"@id":"https://doi.org/10.17182/hepdata.96550.v1/t8","@type":"Dataset","description":"$\\pi^0$ meson $v_4/v_2^2, 20-40\\%$ centrality","name":"Figure 9-2"},{"@id":"https://doi.org/10.17182/hepdata.96550.v1/t9","@type":"Dataset","description":"$\\pi^0$ meson $v_4/v_2^2, 40-60\\%$ centrality","name":"Figure 9-3"},{"@id":"https://doi.org/10.17182/hepdata.96550.v1/t10","@type":"Dataset","description":"$\\pi^0$ meson $v_4/v_2^2, 20-60\\%$ centrality","name":"Figure 9-4"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1254476?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/96550"}],"inLanguage":"en","name":"Azimuthal anisotropy of pi^0 and eta mesons in Au+Au collisions at sqrt(s_NN)=200 GeV","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins1254476?version=1","version":1}
