We invert that dependence to obtain $p_t$ autocorrelations on differences $(\\eta_\\Delta,\\phi_\\Delta)$ interpreted to represent velocity/temperature distributions on ($\\eta,\\phi$). The general form of the autocorrelations suggests that the basic correlation mechanism is parton fragmentation. The autocorrelations vary strongly with collision centrality, which suggests that fragmentation is strongly modified by a dissipative medium in the more central","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.102092.v1/t1","@type":"Dataset","description":"Correlation amplitudes $B_{1}, B_{2}, B_{3}$ as well as positive-peak widths for pseudorapidity ($\\sigma_{\\eta_{1}}$) and azimuth ($\\sigma_{\\phi_{1}}$), plotted on mean participant...","name":"Figure 3"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins693136?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/102092"}],"inLanguage":"en","name":"Transverse-momentum p(t) correlations on (eta,Phi) from mean-p(t) fluctuations in Au - Au collisions at s(NN)**(1/2) = 200-GeV.","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins693136?version=1","version":1}
