Parton cascade and coalescence
Recent data from Au + Au reactions at √ sNN = 130 and 200 GeV from RHIC show striking difference between baryons and mesons in the intermediate transverse momentum region 2 < p⊥ < 5 GeV. First, elliptic flow scales with constituent quark number[ 1, 2, 3, 4, 5]. The flow per constituent quark as a function of transverse momentum per constituent quark, v 2 (pT/n)/n (n = 2 for mesons, 3 for baryon...
متن کاملParton coalescence and spacetime
The influence of spacetime dynamics in hadronization via parton coalescence at RHIC is investigated using covariant parton transport theory. Key observables, the quark number scaling of elliptic flow and the enhancement of the p/π ratio, show strong dynamical effects and differ from earlier results based on the simple coalescence formulas.
متن کاملStrangeness Production via Parton Cascade
We study pre-equilibrium strangeness production at RHIC energies in a new parton cascade. Starting with the turbulent glue HIJING initial conditions we investigate the interplay between mini-jet and soft beam jet gluons for strangeness production prior to hadronization, and show the importance of soft beam jet gluons in the strangeness production.
متن کاملA Relativistic Parton Cascade with Radiation
We consider the evolution of a parton system which is formed at the central rapidity region just after an ultrarelativistic heavy ion collision. The evolution of the system, which is composed of gluons, quarks and antiquarks, is described by a relativistic Boltzmann equations with collision terms including radiation and retardation effects. The equations are solved by the test particle method u...
متن کاملRecent results from parton cascade/microscopic transport
Parton cascade is a microscopic transport approach for the study of the space-time evolution of the Quark-Gluon Plasma produced in relativistic heavy ion collisions and its experimental manifestations. In the following, parton cascade calculations on elliptic flow and thermalization will be discussed. Dynamical evolution is shown to be important for the production of elliptic flow including the...
