Significant large-momentum-scale correlations are observed for charged primary hadrons with $0.15 \\leq p_t \\leq 2$ GeV/$c$ and pseudorapidity $|\\eta| \\leq 1.3$. Such correlations were not observed in a similar study at lower energy and are not predicted by theoretical collision models. Their direct relation to mean-$p_t$ fluctuations measured in the same angular acceptance is demonstrated. Positive correlations are observed for pairs of particles which have large $p_t$ values while negative correlations occur for pairs in which one particle has large $p_t$ and the other has much lower $p_t$. The correlation amplitudes per final state particle increase with collision centrality. The observed correlations are consistent with a scenario in which the transverse momentum of hadrons associated with initial-stage semi-hard parton scattering is dissipated by the medium to lower $p_t$.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.102087.v1/t1","@type":"Dataset","description":"Symmetrized pair-density net ratios $\\widehat{r} [X(p_{t1}),X(p_{t2})]-1$ for all nonidentified charged primary particles for most-central Au-Au collision events at $\\sqrt{s_{NN}}=130$ GeV.","name":"Figure 1 a"},{"@id":"https://doi.org/10.17182/hepdata.102087.v1/t2","@type":"Dataset","description":"Symmetrized pair-density net ratios $\\widehat{r}[X(p_{t1}),X(p_{t2})]-1$ for all nonidentified charged primary particles for mid-central Au-Au collision events at $\\sqrt{s_{NN}}=130$ GeV.","name":"Figure 1 b"},{"@id":"https://doi.org/10.17182/hepdata.102087.v1/t3","@type":"Dataset","description":"Symmetrized pair-density net ratios $\\widehat{r}[X(p_{t1}),X(p_{t2})]-1$ for all nonidentified charged primary particles for mid-peripheral Au-Au collision events at $\\sqrt{s_{NN}}=130$ GeV.","name":"Figure 1 c"},{"@id":"https://doi.org/10.17182/hepdata.102087.v1/t4","@type":"Dataset","description":"Symmetrized pair-density net ratios $\\widehat{r}[X(p_{t1}),X(p_{t2})]-1$ for all nonidentified charged primary particles for peripheral Au-Au collision events at $\\sqrt{s_{NN}}=130$ GeV.","name":"Figure 1 d"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins656302?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/102087"}],"inLanguage":"en","name":"Transverse momentum correlations and minijet dissipation in Au Au collisions at s(NN)**(1/2) = 130-GeV.","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins656302?version=1","version":1}
