>
> Abstract:
>
> We report on the first measurement of anisotropic flow v2(pT) of
> multi-strange baryons Xi+AntiXi and Omega+AntiOmega in heavy-ion
collisions.
> A significant amount of elliptic flow is observed,
> in minimum bias Au+Au collisions at sqrt(sNN) = 200 GeV, for
> multi-strange baryons which are expected to be particularly
> sensitive to the dynamics of the partonic stage of heavy-ion
> collisions. The pT dependence of v2 of the multi-strange baryons
> confirms the number of constituent quark scaling previously
> observed for lighter hadrons. These results support the idea
> that a substantial fraction of the observed collective motion
> is developed at the early partonic stage in ultra-relativistic
> nuclear collisions at RHIC.
