The strangeness content in a QGP is believed to be enhanced from
that of normal hadronic matter [10].
In a QGP there is a high concentration of up and down quarks.
The quarks are fermions and the creation of 
and 
pairs
might be blocked due to the Pauli principle. Then the creation of 
pairs would be favored in spite of their larger mass.
The enhancement might however be explained in a purely hadronic scenario,
where the abundance of strange quarks gradually grows in a chain of
rescattering processes. This complication can be solved by studying
particles not likely to be produced by hadronic rescattering, such as
(consisting of
) and multistrange
baryons.
