A dynamical quark coalescence model for φ and Ω production in heavy-ion collisions at RHIC

摘要

We report the results on the transverse momentum spectra of φ mesons and Ω (Ω~- +Ω~+) baryons as well as their anisotropic flows in Au+Au collisions at RHIC, obtained from a dynamical quark coalescence model that uses the quark phase-space information from a multi-phase transport (AMPT) model within the string melting scenario and includes the quark structure of hadrons.
