Abstract
We study the elliptic flow v_2 of multi-strange hadrons such as the ϕ,
Ξ 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 ϕ 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.
