It introduces a comprehensive model including full baryon octet and kaons with self-consistent interactions, analyzing strangeness production and kaon condensation at finite temperature and density.

Findings

Kaon production depends on the effective chemical potential and interaction scheme.

Kaon condensation may occur at high densities and temperatures.

Different coupling schemes significantly affect strangeness yields.

Abstract

We study the strangeness production in hot and dense nuclear medium, by requiring the conservation of the baryon density, electric charge fraction and zero net strangeness. The hadronic equation of state is investigated 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. The obtained results are compared with a minimal coupling scheme, calculated for different values of the anti-kaon optical potential and with non-interacting kaon particles. In this context, we also consider the possible onset of the kaon condensation for a wide range of temperatures and baryon densities.
