Kaon and strangeness production in an effective relativistic mean field model

We investigate the strangeness production at finite temperature and baryon density by means of an effective relativistic mean-field model with the inclusion of the full octet of baryons and kaon mesons. Kaons are considered taking into account of an effective chemical potential depending on the self-consistent interaction between baryons. In this context, we study the influence of the kaon-nucleon interaction in the determination of the kaon to anti-kaon ratio and in the strangeness production. The results are then compared with a minimal coupling scheme, calculated for different values of the antikaon optical potential.
