Abstract:
We study the elliptic flow v2 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 v2 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. © 2004 Published by Elsevier B.V.
