0 Equilibration within a semiclassical off - shell transport approach ∗

چکیده
Equilibration times for nuclear matter configurations – modelling intermediate and high energy nucleus-nucleus collisions – are evaluated within the semiclassical off-shell transport approach developed recently. The transport equations are solved for a finite box in coordinate space employing periodic boundary conditions. The off-shell transport model is shown to give proper off-shell equilibrium distributions in the limit t → ∞ for the nucleon and ∆-resonance spectral functions. We find that equilibration times within the off-shell approach are only slightly enhanced as compared to the on-shell limit for the momentum configurations considered.

Strange Particle Production and Equilibration at SIS energies within a Semiclassical Off-shell Transport Approach
W. Cassing, S. Juchem University of Giessen Recently we have formulated a novel transport approach that incorporates the propagation of particles off the massshell [1]. It goes beyond the conventional transport description within the on-shell quasiparticle limit to propagate particles with a finite lifetime by means of a dynamical spectral function. This spectral function is directly determined...

The transport of hadrons with dynamical spectral functions A h (X, P , M 2) is studied for nucleus-nucleus collisions at SIS and AGS energies in comparison to the conventional quasi-particle limit and the available experimental data within the recently developed off-shell HSD transport approach. Similar to reactions at GANIL energies the off-shell effects show up in high momentum tails of the p...

متن کاملDileptons and Hadron Spectral Functions in Heavy-ion Collisions
We briefly review the dilepton experiments at BEVALAC/SIS and SPS energies for p+ p, p+A and A+A collisions as well as our present understanding of the data within transport theoretical simulations. Since dileptons from p + A and A + A collisions in particular probe the inmedium spectral functions of vector mesons, a novel semiclassical offshell transport approach is introduced on the basis of ...
