Query: Hyperon Enhancement in the Dual Parton Model   We review the two sources of hyperon enhancement in the dual parton model:
strings originating from diquark-antidiquark pairs in the nucleon sea and net
baryons containing two or three sea quarks with a yield controlled by the
observed stopping. We show that adding final state interactions (including
strangeness exchange reactions as well as the inverse reactions required by
detailed balance) with a single averaged cross-section $\sigma=0.2$ mb, we can
explain the observed hyperon enhancement in PbPb collisions at CERN SPS.
