The Ideal

Large elliptic flow at RHIC seems to indicate that ideal hydrodynamics provides a good description of Au – Au collisions, at least at the maximum RHIC energy. The medium formed has been interpreted as a nearly perfect (low-viscosity) liquid, and connections have been made to gravitation through string theory. Recently, claimed observations of large flow fluctuations comparable to participant eccentricity fluctuations seem to confirm the ideal hydro scenario. However, determination of the azimuth quadrupole with 2D angular autocorrelations, which accurately distinguish "flow" (quadrupole) from "nonflow" (minijets), contradicts conventional interpretations. Centrality trends may depend only on the initial parton geometry, and methods used to isolate flow fluctuations are sensitive instead mainly to minijet correlations. The results presented in this paper suggest that the azimuth quadrupole may be a manifestation of gluonic multipole radiation.

String Fragmentation

The new issue of parton and hadron cascade model PACIAE 2.1 is utilized investigating the charged particle elliptic flow parameter v2 in Au + Au and p+ Au collisions at top RHIC energy. If the transverse momenta px and py of particles from string fragmentation are randomly sampled on the circumference of an ellipse instead of circle originally the PHENIX charged particle v2(η) and v2(pT) data in the 20-40% and 40-50% central Au + Au collisions at [Formula: see text] are fairly reproduced by the PACIAE 2.1 calculations, respectively. In addition, the charged particle v2(η) and v2(pT) in the p+ Au collisions at [Formula: see text] are predicted. It turned out that the charged particle elliptic flow parameter v2 may reach a measurable value of ~0.04 in the above p+ Au collisions.
