Recently the recombination of thermalized valence quarks has proposed as the dominant mechanism for the production of hadrons at intermediate transverse momentum (2-4 GeV/c) in relativistic heavy ion collisions. A lot of evidence that suggests the quark recombination has been found in the RHIC data, such as hadron spectra, ratios of hadron yield, nuclear modification factors and elliptic flow as a function of transverse momentum. Especially the quark number scaling in elliptic flow strongly shows the validity of dominance of the recombination mechanism in hadronization. Furthermore the more detailed argument about physical observables at RHIC (correlated emission of hadrons, event-by-event fluctuations, hadronization time, entropy problem) has been done from the point of view of the quark recombination. I will also discuss the recent progress of the quark recombination/coalescence model at RHIC.
