Ω and ϕ production in Au+Au collisions at

\sqrt{s_{N N}}

= 11.5 and 7.7 GeV in a dynamical quark coalescence model

摘要

Abstract

The ,Ω, and ,ϕ, production in relativistic heavy-ion collisions is studied in a dynamical quark coalescence model using the phase space information of strange quarks from a multiphase transport (AMPT) model. Enhanced local parton density fluctuation is implemented in the AMPT to simulate the QCD phase transition dynamics. By studying the transverse momentum ,p,T, spectra and the elliptic flow of the multi-strangeness particles, such as,Ω, and ,ϕ, and the ,Ω,/,ϕ, ratio as a function of ,p,T, in the AMPT, we find that the new development improves the description of experimental data. The study motivates further experimental investigations of ,Ω, and ,ϕ, production in Phase-II of the Beam Energy Scan program at RHIC.
