Hadron production in hot and dense nuclear matter    [PDF]

A. Lavagno

We study the hadron production at finite values of temperature and baryon
density by means of an effective relativistic mean-field model with the
inclusion of the full octet of baryons, the Delta-isobar degrees of freedom and
the lightest pseudoscalar and vector mesons. These last particles are
considered in the so-called one-body contribution, taking into account of an
effective chemical potential and mass depending on the self-consistent
interaction between baryons. The analysis is performed by requiring the Gibbs
conditions on the global conservation of baryon number, electric charge
fraction and zero net strangeness. In this context, we study the behavior of
different particle-antiparticle ratios and strangeness production.
