چکیده

The effects of shape of the freeze-out hypersurface and resonance decays on the pion correlation functions in relativistic heavy-ion collisions are studied with help of the hydro-inspired models with single freeze-out. The heavy-ion Monte-Carlo generator THERMINATOR is used to generate hadronic events describing production of particles from a thermalized and expanding source. We find that the short-lived resonances increase the pionic HBT radii by about 1 fm. We also find that the pion HBT data from RHIC are fully compatible with the single freeze-out scenario provided a special choice of the freeze-out hypersurface is made.

We calculate the in-medium D meson self-energies in a hot pion gas induced by resonance interactions with pions. The appropriate resonances in the s, p and d waves of the D meson-pion pair are represented by low lying scalar, vector and tensor D∗ mesons. At temperatures around 200 MeV the D-meson mass drops by 30 MeV and the scattering width grows up to 60 MeV. Similar medium effects are found ...
