As a result, higher-order cumulants and their ratios are predicted to be negative, $C_{6}/C_{2}$ < 0, for example. In this paper, we report the first measurement of the midrapidity net-proton $C_{6}/C_{2}$ from 27, 54.4 and 200 GeV Au+Au collisions at RHIC. The dependence on collision centrality and kinematic acceptance in ($p_{T}$ , $y$) are analyzed. While for 54.4 GeV collisions, most of C6/C2 values are larger or equal to zero, it is observed that for 27 and 200 GeV collisions, the values of C6/C2 progressively become negative from peripheral to central collisions. Transport model calculations without critical dynamics predict values around zero. These observations seem in favor of a smooth crossover in the high energy nuclear collisions at RHIC.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.105720.v1/t1","@type":"Dataset","description":"Event by event net-proton multiplicity, $\\Delta N_{p}$, distributions for Au+Au collisions at \u221asNN = 27, 54.4, and 200 GeV in...","name":"Figure 1, 27 GeV 0-10%"},{"@id":"https://doi.org/10.17182/hepdata.105720.v1/t2","@type":"Dataset","description":"Event by event net-proton multiplicity, $\\Delta N_{p}$, distributions for Au+Au collisions at \u221asNN = 27, 54.4, and 200 GeV in...","name":"Figure 1, 27 GeV 30-40%"},{"@id":"https://doi.org/10.17182/hepdata.105720.v1/t3","@type":"Dataset","description":"Event by event net-proton multiplicity, $\\Delta N_{p}$, distributions for Au+Au collisions at \u221asNN = 27, 54.4, and 200 GeV in...","name":"Figure 1, 54.4 GeV 0-10%"},{"@id":"https://doi.org/10.17182/hepdata.105720.v1/t4","@type":"Dataset","description":"Event by event net-proton multiplicity, $\\Delta N_{p}$, distributions for Au+Au collisions at \u221asNN = 27, 54.4, and 200 GeV in...","name":"Figure 1, 54.4 GeV 30-40%"},{"@id":"https://doi.org/10.17182/hepdata.105720.v1/t5","@type":"Dataset","description":"Event by event net-proton multiplicity, $\\Delta N_{p}$, distributions for Au+Au collisions at \u221asNN = 27, 54.4, and 200 GeV in...","name":"Figure 1, 200 GeV 0-10%"},{"@id":"https://doi.org/10.17182/hepdata.105720.v1/t6","@type":"Dataset","description":"Event by event net-proton multiplicity, $\\Delta N_{p}$, distributions for Au+Au collisions at \u221asNN = 27, 54.4, and 200 GeV in...","name":"Figure 1, 200 GeV 30-40%"},{"@id":"https://doi.org/10.17182/hepdata.105720.v1/t7","@type":"Dataset","description":"Net-proton $C_{6}/C_{2}$ as a function of rapidity (left) and transverse momentum acceptance (right) from $\\sqrt{s_{NN}}$ = 27 GeV (crosses), 54.4...","name":"Figure 2, 27 GeV rapidity dependence"},{"@id":"https://doi.org/10.17182/hepdata.105720.v1/t8","@type":"Dataset","description":"Net-proton $C_{6}/C_{2}$ as a function of rapidity (left) and transverse momentum acceptance (right) from $\\sqrt{s_{NN}}$ = 27 GeV (crosses), 54.4...","name":"Figure 2, 27 GeV $p_{T}$ dependence"},{"@id":"https://doi.org/10.17182/hepdata.105720.v1/t9","@type":"Dataset","description":"Net-proton $C_{6}/C_{2}$ as a function of rapidity (left) and transverse momentum acceptance (right) from $\\sqrt{s_{NN}}$ = 27 GeV (crosses), 54.4...","name":"Figure 2, 54.4 GeV rapidity dependence"},{"@id":"https://doi.org/10.17182/hepdata.105720.v1/t10","@type":"Dataset","description":"Net-proton $C_{6}/C_{2}$ as a function of rapidity (left) and transverse momentum acceptance (right) from $\\sqrt{s_{NN}}$ = 27 GeV (crosses), 54.4...","name":"Figure 2, 54.4 GeV $p_{T}$ dependence"},{"@id":"https://doi.org/10.17182/hepdata.105720.v1/t11","@type":"Dataset","description":"Net-proton $C_{6}/C_{2}$ as a function of rapidity (left) and transverse momentum acceptance (right) from $\\sqrt{s_{NN}}$ = 27 GeV (crosses), 54.4...","name":"Figure 2, 200 GeV rapidity dependence"},{"@id":"https://doi.org/10.17182/hepdata.105720.v1/t12","@type":"Dataset","description":"Net-proton $C_{6}/C_{2}$ as a function of rapidity (left) and transverse momentum acceptance (right) from $\\sqrt{s_{NN}}$ = 27 GeV (crosses), 54.4...","name":"Figure 2, 200 GeV $p_{T}$ dependence"},{"@id":"https://doi.org/10.17182/hepdata.105720.v1/t13","@type":"Dataset","description":"Collisions centrality dependence of net-proton $C_{6}/C_{2}$ in Au+Au collisions for |$y$| < 0.5 and 0.4 < $p_{T}$ (GeV/c) < 2.0....","name":"Figure 3, 27 GeV"},{"@id":"https://doi.org/10.17182/hepdata.105720.v1/t14","@type":"Dataset","description":"Collisions centrality dependence of net-proton $C_{6}/C_{2}$ in Au+Au collisions for |$y$| < 0.5 and 0.4 < $p_{T}$ (GeV/c) < 2.0....","name":"Figure 3, 54.4 GeV"},{"@id":"https://doi.org/10.17182/hepdata.105720.v1/t15","@type":"Dataset","description":"Collisions centrality dependence of net-proton $C_{6}/C_{2}$ in Au+Au collisions for |$y$| < 0.5 and 0.4 < $p_{T}$ (GeV/c) < 2.0....","name":"Figure 3, 200 GeV"},{"@id":"https://doi.org/10.17182/hepdata.105720.v1/t16","@type":"Dataset","description":"Distributions of reconstructed protons (black circles) from embedding simulations in 200 GeV Au+Au collisions at 0-2.5% centrality.
