| Abstract: | We investigate the role of the central two-body nucleon-nucleon correlations on typical quantities observed in relativistic
heavy-ion collisions. Basic correlation measures, such as the fluctuations of the participant eccentricity, initial size fluctuations,
or the fluctuations of the number of sources producing particles, are sensitive at the level 10–20% to the inclusion of the
two-body correlations. However, the realistic correlation function gives virtually indistinguishable results from the hard-core repulsion with the expulsion distance set to ∼0.9 fm. In the second part of the talk we compare the spherical and Gaussian wounding
profiles and find that the latter, which is more realistic, leads to reduced eccentricity and fluctuations. This has significance
for precision studies of the elliptic flow. |
