Resonance Absorption and Regeneration in Relativistic Heavy Ion Collisions

TL;DR

This paper investigates how hadronic resonances such as Delta, rho, and phi are regenerated during heavy ion collisions, focusing on their time evolution and emission spectra after chemical freeze-out at SPS and SIS-300 energies.

Contribution

It provides a detailed analysis of resonance regeneration processes and emission time spectra, highlighting the importance of post-freeze-out resonance dynamics in heavy ion collisions.

Findings

Resonance regeneration occurs significantly after chemical freeze-out.

Emission time spectra reveal the timing of resonance detectability.

Time evolution models improve understanding of resonance behavior in collisions.

Abstract

The regeneration of hadronic resonances is discussed for heavy ion collisions at SPS and SIS-300 energies. The time evolutions of Delta, rho and phi resonances are investigated. Special emphasize is put on resonance regeneration after chemical freeze-out. The emission time spectra of experimentally detectable resonances are explored.
