Baryon‐strangeness correlations (CBS) are studied with a hadron/string transport approach (UrQMD) and a dynamical quark recombination model (quark molecular dynamics, qMD) for various energies from Elab = 4A GeV to sNN = 200 GeV. As expected, we find that the hadron/string dynamics shows correlations similar to a simple hadron gas. In case of the quark molecular dynamics, we find that initially the CBS correlation is that of a weakly interacting QGP but changes in the process of hadronization also to the value for a hadron gas. Therefore, we conclude that the hadronization process itself makes the initial baryon strangeness correlation unobservable. To make an experimental study of this observable more feasible, we also investigate how a restriction to only charged kaons and Λ’s (instead of all baryons and all strange particles) influences the theoretical result on CBS. We find that a good approximation of the full result can be obtained in this limit in the present simulation.
