Measurements of intermediate p T (1.5 < p T < 5.0 GeV/ c ) identified particle distributions in heavy-ion collisions at SPS and RHIC energies display striking dependences on the number of constituent quarks in the corresponding hadron. One finds that elliptic flow at intermediate p T follows a constituent quark scaling law as predicted by models of hadron formation through coalescence. In addition, baryon production is also found to increase with event multiplicity much faster than meson production. The rate of increase is similar for all baryons and seemingly independent of mass. This indicates that the number of constituent quarks determines the multiplicity dependence of identified hadron production at intermediate p T . We review these measurements and interpret the experimental findings.
