Description
We discuss updated results on the properties of strange mesons in nuclear matter at finite temperature from a chiral unitary approach in coupled channels, which incorporates the s- and p-waves of the kaon nuceon interaction. As a novelty, the in-medium scattering amplitudes and cross sections in several channels (such as Kbar N -> pi Sigma) are obtained in addition to the (off-shell) K and Kbar spectral functions and quasi-particle properties, which is of particular interest for microscopic transport evaluations of strangeness production and propagation in heavy-ion collisions.
A reminder of previous results and comparison to data from the HSD transport approach, relying on a G-matrix calculation of strange meson spectral functions within a meson-exchange model, is presented. Progress on our understanding of strange meson interactions with hadronic matter, in view of in-medium cross sections within the chiral unitary model, is discussed.
