K* dynamics in heavy-ion collisions — •Andrej Ilner, Daniel Cabrera, and Elena Bratkovskaya — Frankfurt Institute for Advanced Studies, Frankfurt am Main, Germany

The dynamics of strange vector meson resonances (K* and anti-K*) in heavy-ion collisions is studied within the off-shell microscopic Parton-Hadron-String Dynamics (PHSD) transport approach. In-medium modification of the(anti-)K* properties in hot and dense environment is accounted for the production of resonances at hadronisation as well as at the hadronic (anti-)K + pion reactions. We investigate the influence of the in-medium effects on the final experimental observables. Since experimentally K*'s resonances are reconstructed via their decay to kaons and pion, we study the "distortion" of the true K*'s spectra by hadronic rescattering and absorption of the decay particles (K's and pions) at relativistic energies.
