A closer look at the influence of tubular initial conditions on two-particle correlations

Abstract

In a recent paper, the hydrodynamic code NEXSPheRIO was used in conjunction with STAR analysis methods to study two-particle correlations as function of Delta-eta and Delta-phi. The various structures observed in data were reproduced. In this work, we discuss the origin of these structures as well as present new results.
