Elliptic flow of multi-strange particles: fragmentation, recombination and hydrodynamics
نویسندگان
چکیده
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.

The first measurement of the elliptic transverse flow for multi-strange baryons Ξ and Ω 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 Ξand Ξ + indicates that these particles might be emitted from the system at a high temperature (∼ 150 MeV) ...
متن کاملStrange hadron ( K 0 S , Λ and Ξ ) elliptic flow from 200 GeV
Collective flow reflects dynamical evolution in high-energy heavy ion collisions. In particular, the strange hadron elliptic flow reflects early collision dynamics [ 1]. We present results from a systematic analysis of the centrality dependence of strange hadron elliptic flow (v 2) measurement of K 0 S , Λ and Ξ for Cu + Cu collisions at 200 GeV. Results for Cu + Cu collisions are compared with...

Azimuthal and pseudo-rapidity correlations with strange particles at intermediate-p T at RHIC Abstract. We present results on two-particle azimuthal correlations with strange trigger particles (K 0 S , Λ, Ξ, Ω) associated with unidentified charged particles in d+Au and Au+Au collisions at √ s N N = 200 GeV. We investigate, in detail, the nearside associated yield as a function of centrality, p ...
متن کاملCFD Hydrodynamics Analysis of Syngas Flow in Slurry Bubble Column
In this paper, a CFD model of syngas flow in slurry bubble column was developed. The model is based on an Eulerian-Eulerian approach and includes three phases: slurry of solid particles suspended in paraffin oil and syngas bubbles. Numerical calculations carried out for catalyst particles, bubble coalescence and breakup included bubble-fluid drag force and interfacial area effects. Also, the ef...
