Phase-Space Coalescence for heavy and light quarks at RHIC

摘要

We review the application and successes of a phase-space coalescence plusfragmentation model that has been applied for hadronization at RHIC. Thephysical concept is discussed together with the practical implementation. Therobustness of main predictions is reviewed together with several open issueslike relevance of three dimensional calculation, finite width of the wavefunctions, effects of quark masses, energy-entropy conservation, space-momentumcorrelation. Eventually the relevance of coalescence also for the study of themicroscopic interaction of heavy quarks is highlighted.
