In the 0-60\\% centrality class, the nuclear modification factors ($R_{\\mathrm{AA}}$), which quantify the level of yield suppression in heavy-ion collisions compared to p+p collisions, for $\\Upsilon$(1S) and $\\Upsilon$(2S) are $0.40 \\pm 0.03~\\textrm{(stat.)} \\pm 0.03~\\textrm{(sys.)} \\pm 0.09~\\textrm{(norm.)}$ and $0.26 \\pm 0.08~\\textrm{(stat.)} \\pm 0.02~\\textrm{(sys.)} \\pm 0.06~\\textrm{(norm.)}$, respectively, while the upper limit of the $\\Upsilon$(3S) $R_{\\mathrm{AA}}$ is 0.17 at a 95\\% confidence level. This provides experimental evidence that the $\\Upsilon$(3S) is significantly more suppressed than the $\\Upsilon$(1S) at RHIC. The level of suppression for $\\Upsilon$(1S) is comparable to that observed at the much higher collision energy at the Large Hadron Collider. These results point to the creation of a medium at RHIC whose temperature is sufficiently high to strongly suppress excited $\\Upsilon$ states.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.133217.v2/t1","@type":"Dataset","description":"Inclusive Y(1S) $R_{AA}$ as a function of centrality in Au+Au collisions at 200 GeV.
