For associated particles at higher pT > 2.5 GeV\\c, narrow correlation peaks are seen in d+Au and Au+Au, indicating that the main production mechanism is jet fragmentation. At lower associated particle pT < 2 GeV/c, a large enhancement of the near- (dphi ~ 0) and away-side (dphi ~ pi) associated yields is found, together with a strong broadening of the away-side azimuthal distributions in Au+Au collisions compared to d+Au measurements, suggesting that other particle production mechanisms play a role. This is further supported by the observed significant softening of the away-side associated particle yield distribution at dphi ~ pi in central Au+Au collisions.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.100593.v1/t1","@type":"Dataset","description":"Background-subtracted azimuthal angle difference distributions for associated particles with pT between 1.0 and 2.5 GeV/c and for different ranges of...","name":"Figure 2 and Figure 10 - part 1"},{"@id":"https://doi.org/10.17182/hepdata.100593.v1/t2","@type":"Dataset","description":"Background-subtracted azimuthal angle difference distributions for associated particles with pT between 1.0 and 2.5 GeV/c and for different ranges of...","name":"Figure 2 and Figure 10 - part 2"},{"@id":"https://doi.org/10.17182/hepdata.100593.v1/t3","@type":"Dataset","description":"Background-subtracted azimuthal angle difference distributions for different trigger particle pT and associated pT in 0-12% central Au+Au collisions and d+Au...","name":"Figure 3 and Figure 11"},{"@id":"https://doi.org/10.17182/hepdata.100593.v1/t4","@type":"Dataset","description":"The angle Delta between the away-side peaks and DeltaPhi = pi for 4 < pT_trig < 6 GeV/c in 0-12%...","name":"Figure 5"},{"@id":"https://doi.org/10.17182/hepdata.100593.v1/t5","@type":"Dataset","description":"Near-side (|dphi| < 0.9) associated yield per trigger particle for various trigger particle pT selections as a function of associated...","name":"Figure 6a"},{"@id":"https://doi.org/10.17182/hepdata.100593.v1/t6","@type":"Dataset","description":"Near-side (|dphi| < 0.9) ratios of the per-trigger associated yields in central Au+Au and d+Au collisions.","name":"Figure 6b"},{"@id":"https://doi.org/10.17182/hepdata.100593.v1/t7","@type":"Dataset","description":"Away-side (|dphi| > 0.9) associated yield per trigger particle for various trigger particle pT selections as a function of associated...","name":"Figure 6c"},{"@id":"https://doi.org/10.17182/hepdata.100593.v1/t8","@type":"Dataset","description":"Away-side (|dphi| > 0.9) ratios of the per-trigger associated yields in central Au+Au and d+Au collisions.","name":"Figure 6d"},{"@id":"https://doi.org/10.17182/hepdata.100593.v1/t9","@type":"Dataset","description":"Mean transverse momentum  of associated particles with 0.25 < pT,assoc < 4.0 GeV/c, for four different centrality selections.","name":"Figure 8"},{"@id":"https://doi.org/10.17182/hepdata.100593.v1/t10","@type":"Dataset","description":"Mean transverse momentum  (DeltaPhi) of associated hadrons in the range 0.25 < pT_assoc < 4.0 GeV/c in the core...","name":"Figure 9"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins851937?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/100593"}],"inLanguage":"en","name":"Azimuthal di-hadron correlations in d+Au and Au+Au collisions at $\\sqrt{s_{NN}}=200$ GeV from STAR","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins851937?version=1","version":1}
