Elliptic flow of multi-strange baryons Xi and Omega in Au+Au collisions   at sqrt(s_NN)=200 GeV
  The first measurement of the elliptic transverse flow for multi-strange baryons Xi and Omega in high energy heavy ion collisions is presented, which may indicate the presence of partonic collectivity. A hydrodynamically inspired model fit to the transverse momentum spectra and elliptic flow of Xi- and AntiXi+ indicates that these particles might be emitted from the system at a high temperature (~150 MeV) with significant radial transverse flow and that the emitting system is spatially asymmetric.
