We compare our large-acceptance measurements at CM energies $\\sqrt{s_{NN}} =$ 19.6, 62.4, 130 and 200 GeV to SPS measurements at 12.3 and 17.3 GeV. $p_t$ angular correlation structure suggests that the principal source of $p_t$ correlations and fluctuations is minijets (minimum-bias parton fragments). We observe a dramatic increase in correlations and fluctuations from SPS to RHIC energies, increasing linearly with $\\ln \\sqrt{s_{NN}}$ from the onset of observable jet-related $<p_{t}>$ fluctuations near 10 GeV.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.102948.v1/t1","@type":"Dataset","description":"Per-particle fluctuation dependence on pseudorapidity scale $\\delta\\eta$ in central collisions.","name":"Table 3a"},{"@id":"https://doi.org/10.17182/hepdata.102948.v1/t2","@type":"Dataset","description":"Per-particle fluctuation dependence on pseudorapidity scale $\\delta\\eta$ in central collisions.","name":"Table 3c"},{"@id":"https://doi.org/10.17182/hepdata.102948.v1/t3","@type":"Dataset","description":"Centrality dependence of $$ fluctuations in the STAR acceptance for four energies. $\\nu$ is the mean participant path length (please...","name":"Table 3b"},{"@id":"https://doi.org/10.17182/hepdata.102948.v1/t4","@type":"Dataset","description":"$\\sqrt{s_{NN}}$ dependence of $$ fluctuations for central collisions and STAR full acceptance.
