Vector mesons in matter

Research output: Contribution to journalArticle

Abstract

One consequence of the chiral restoration is the mixing of parity partners. We look for a possible signature of the mixing of vector and axial vector mesons in heavy-ion collisions. We suggest an experimental method for its observation. The dynamical evolution of the heavy-ion collision is described by a transport equation of QMD-type evolving nucleons. N* and Δ resonances, Λ's and Σ baryons, and furthermore, π's, η's ρ's σ's ω's and kaons with their isospin degrees of freedom. The input cross-sections and resonance parameters of the model are fitted to the available nucleon-nucleon and pion-nucleon cross-sections.
