In minimum bias collisions the $v_{2}$ of the $\\phi$ meson is consistent with the trend observed for mesons. The ratio of the yields of the $\\Omega$ to those of the $\\phi$ as a function of transverse momentum is consistent with a model based on the recombination of thermal $s$ quarks up to $p_{T}$\u223c4 GeV/c, but disagrees at higher momenta. The nuclear modification factor ($R_{CP}$) of $\\phi$ follows the trend observed in the $K^{0}_{S}$ mesons rather than in $\\Lambda$ baryons, supporting baryon-meson scaling. Since $\\phi$-mesons are made via coalescence of seemingly thermalized s quarks in central Au+Au collisions, the observations imply hot and dense matter with partonic collectivity has been formed at RHIC.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.98969.v1/t1","@type":"Dataset","description":"The elliptic flow, $v_{2}$($p_{T}$), for the $\\phi$-meson as a function of centrality.
