Abstract

In the framework of a multi-phase transport model, initial fluctuations in the transverse parton density lead to all orders of harmonic flows. Hadron-triggered azimuthal correlations include all contributions from harmonic flows, hot spots, and jet-medium excitations, which are isolated by using different initial conditions. We found that different physical components dominate different pseudorapidity ranges of dihadron correlations. Because γ-triggered azimuthal correlations can only be caused by jet-medium interactions, a comparative study of hadron- and γ -triggered azimuthal correlations can reveal more dynamics about jet-medium interactions.

Jets, Mach Cones, Hot Spots, Ridges, Harmonic Flow, Dihadron, and {gamma}-Hadron Correlations in High-Energy Heavy-Ion Collisions

Journal Article Guoliang, Ma ; Xinnian, Wang ; Nuclear Science Division MS 70R0319, Lawrence Berkeley National Laboratory, Berkeley, California 94720 - Physical Review Letters

Within the AMPT Monte Carlo model, fluctuations in the initial transverse parton density are shown to lead to harmonic flows. The net back-to-back dihadron azimuthal correlation after subtraction of contributions from harmonic flows still has a double peak that is independent of the initial geometric triangularity and unique to the jet-induced Mach cone and expanding hot spots distorted by radial flow. The longitudinal structure of hot spots also leads to a nearside ridge in dihadron correlation with a large rapidity gap. By successively randomizing the azimuthal angle of the transverse momenta and positions of initial partons, one can isolate themore »« less

Effects of triangular flow on di-hadron azimuthal correlations in relativistic heavy ion collisions

Journal Article Jun, Xu ; Ko, Che Ming - Physical Review. C, Nuclear Physics

Using the AMPT model for relativistic heavy ion collisions, we have studied the di-hadron azimuthal angular correlations triggered by emitted jets in Au+Au collisions at center-of-mass energy {radical}(s{sub NN})=200 GeV and impact parameter b=8 fm. A double-peak structure for the associated particles at the away side of trigger particles is obtained after subtracting background correlations due to the elliptic flow. Both the near-side peak and the away-side double peaks in the azimuthal angular correlations are, however, significantly suppressed (enhanced) in events of small (large) triangular flow or triangularity in the initial collision geometry as a result of fluctuations.

Dependence of ridge formation on trigger azimuth: Correlated emission model

Journal Article Chiu, Charles B ; Hwa, Rudolph C - Physical Review. C, Nuclear Physics

Ridge formation in near-side correlation in heavy-ion collisions is studied in the framework of a phenomenological model called the correlated emission model. Successive soft emissions due to jet-medium interaction lead to the enhancement of thermal partons that follow the local flow directions. The correlation between the flow direction and the semihard parton direction is the major factor that causes the ridge formation to depend on the trigger direction relative to the reaction plane. With the use of a few parameters we have been able to reproduce the data on the ridge yields as functions of the trigger azimuthal angle formore »« less
