Quark recombination model
lOther possible production mechanism of high pt hadrons than the frag.
lQuarks, anti-quarks combine to form mesons and baryons from universal quark distribution, w.
lMesons from 2 q with 1/2 of pT,
baryons from 3 q with 1/3 of pT.
l Bacause of the steep distr. of w, this process wins at
mid-pt.
lCharacteristic scaling features
expected.
