and production in relativistic heavy-ion collisions in a dynamical quark coalescence model Academic Article uri icon

abstract

  • Based on the phase-space information obtained from a multiphase transport model within the string-melting scenario for strange and antistrange quarks, we study the yields and transverse-momentum spectra of mesons and (-++) baryons and their anisotropic flows in Au + Au collisions at RHIC using a dynamical quark coalescence model that includes the effect from quark phase-space distributions inside hadrons. With current quark masses and fixing the and radii from fitting measured yields, we first study the ratio of the yield of baryons to that of mesons as well as their elliptic and fourth-order flows as functions of their transverse momentum. How the elliptic and fourth-order flows of mesons and baryons are related to those of strange and antistrange quarks is then examined. The dependence of these results on and radii as well as on the strange quark mass is also studied. 2006 The American Physical Society.
