Multi-strange baryon elliptic flow in Au+Au collisions at sqrt(s_NN)= 200 GeV

Abstract

We report on the first measurement of elliptic flow $v_2(p_T)$ of multi-strange baryons $\Xi +\overline{Xi}$ and $\Omega +\overline{Omega}inheavy-ioncollisions.InminimumbiasAu+Aucollisionsatsqrt(s_{N}N)=200GeV,asignificantamountofellipticflow,comparabletoothernon-strangebaryons,isobservedformulti-strangebaryonswhichareexpectedtobeparticularlysensitivetothedynamicsofthepartonicstageofheavy-ioncollisions.The$p_T$dependenceof$v_2$ 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.
