FYI
Subject: new paper from Phobos

> This paper presents measurements of the elliptic flow of charged  
> particles
> as a function of pseudorapidity and centrality from Cu-Cu collisions at
> 62.4 and 200 GeV using the PHOBOS detector at the Relativistic Heavy Ion
> Collider (RHIC). The elliptic flow in Cu-Cu collisions is found to be
> significant even for the most central events. For comparison with the
> Au-Au results, it is found that the detailed way in which the collision
> geometry (eccentricity) is estimated is of critical importance when
> scaling out system-size effects. A new form of eccentricity, called the
> participant eccentricity, is introduced which yields a scaled elliptic
> flow in the Cu-Cu system that has the same relative magnitude and
> qualitative features as that in the Au-Au system.
