Triangular flow in event-by-event ideal hydrodynamics in Au+Au collisions at √SNN = 200A GeV
Abstract
The first calculation of triangular flow ν3 in Au+Au collisions at √sNN = 200A GeV
from an event-by-event (3 + 1) d transport+hydrodynamics hybrid approach is presented.
As a response to the initial triangularity Ie{cyrillic, ukrainian}3 of the collision
zone, ν3 is computed in a similar way to the standard event-plane analysis for elliptic
flow ν2. It is found that the triangular flow exhibits weak centrality dependence
and is roughly equal to elliptic flow in most central collisions. We also explore
the transverse momentum and rapidity dependence of ν2 and ν3 for charged particles
as well as identified particles. We conclude that an event-by-event treatment of the
ideal hydrodynamic evolution startingwith realistic initial conditions generates the
main features expected for triangular flow. © 2010 The American Physical Society.

in particular studying highly energetic collisions of heavy nuclei, with which one
aims to create a primordial state of matter at extremely high temperatures and densities
(the Quark-Gluon-Plasma) that resembles the composition of the early Universe shortly
after the Big Bang. It has been only in the last two decades that accelerators have
been in operation that give us the capabilities
