Jet color chemistry and anomalous baryon production in <Emphasis Type="Italic">AA</Emphasis>-collisions

We study anomalous high-p _T baryon production in AA-collisions due to formation of the two parton collinear gq system in the anti-sextet color state for quark jets and gg system in the decuplet/anti-decuplet color states for gluon jets. Fragmentation of these states, which are absent for NN-collisions, after escaping from the quark–gluon plasma leads to baryon production. Our qualitative estimates show that this mechanism can be potentially important at RHIC and LHC energies.
