Quark recombination model (RECO)
lQuarks, anti-quarks combine to
form mesons and
baryons from universal quark distribution,
w(pt).
QGP
Hadron
Mom. distr. of meson (2q)；
Mom. distr. of baryon (3q)；
w(pt)；
Universal mom.distr. of quarks
｛steep
in pt｝
Because of the steep distr.
of w(pt), RECO wins at high pt even w. small Cx.
Characteristic scaling features
expected.
