Abstract
We study the elliptic flow $v_2$ of multi-strange hadrons such as the $Ï$, $Î$ and $Ω$ as a function of transverse momentum in the recombination and fragmentation model and compare to a standard hydrodynamic calculation. We find that the measurement of $v_2$ for the $Ï$ and $Ω$ will allow for the unambiguous distinction between parton recombination and statistical hadro-chemistry to be the dominant process in hadronization at intermediate transverse momenta.
