Higher-order anisotropies in the Blast-Wave Model - disentangling flow and density field anisotropies

Abstract

We formulate a generalisation of the blast-wave model which is suitable for the description of higher order azimuthal anisotropies of the hadron production. The model includes anisotropy in the density profile as well as an anisotropy in the transverse expansion velocity field. We then study how these two kinds of anisotropies influence the single-particle distributions and the correlation radii of two-particle correlation functions. Particularly we focus on the third-order anisotropy and consideration is given to the averaging over different orientation of the event plane.

13 pages, 10 figures; This is the version accepted for publication. The main change comparing to previous version is addition of a new Section and four new figures where we illustrate the model on very simple comparison to data from top RHIC energy
