Erratum: Transport model study of nuclear stopping in heavy-ion collisions over the energy range from 0.09 A to 160 A GeV [Phys. Rev. C 81, 034913 (2010)]

Rapidity distribution of protons from the potential version of UrQMD model and the traditional coalescence afterburner

“…1. Second, the mean-field potential modifications for both "pre-formed" hadrons and formed baryons in UrQMD/M widen the rapidity distributions (as a result, to reduce the yields at mid-rapidity) especially for HICs at higher beam energies, which had been found in the previous calculations [9,13]. The additional pressure (and stopping) at the early compression stage leads to, however, less two-body collisions at the later expansion stage and earlier freeze-outs, which results in as a whole weaker stopping power.…”

“…Among them, the experimental observables related to protons should be theoretically investigated and described well firstly since nucleons are initial particles and heavily influenced by the whole dynamical evolution process and all other newly produced particles come directly or indirectly from the collisions between nucleons. However, it is noticed that even the yields of free (net) protons emitted from HICs at AGS and SPS energies [12] are not well described in the framework of microscopic transport models such as the Ultra-relativistic Quantum Molecular Dynamics (UrQMD) model [13] (using the cascade mode, and called UrQMD/C), which will be focused in this paper. In the FOPI experimental article of Ref.…”

Production and Rescattering of Strange Baryons at Energies Available at the Cern Super Proton Synchrotron in a Transport Model With Hadron Potentials

“…Although the net-proton yield and the rapidity distributions of (anti-)protons are better described [36,40] by the mean-field potential version, a further refinement is still required. The dynamic process of particles in the dense medium induced by both the new (QGP) phase and the hadronic phase afterwards should be investigated with a theoretical breakthrough.…”

“…7 at t = 30 fm/c, and (3) mally large, the medium effect of cross sections on the production and the rescattering of multi-strange baryons should show importance and deserves more investigations. Second, the production of (anti-) protons at AGS and SPS energies are still an open problem [31,40].…”

“…Since the UrQMD model inherits the basic treatment of the baryonic equation of motion in the QMD model [37], the consideration of the mean-field contribution is also logical. In order to properly describe the physical process in HICs at SIS energies this term has been treated carefully in the UrQMD model before [38][39][40]. With the increase of beam energy from SIS, AGS, SPS, up to RHIC, the dynamics of the transport has being attracted more and more attention due to the fact that quite a few of discrepancies between cascade calculations, of any microscopic transport models, and experimental data have been shown in these beam energy regions, such as the collective flows [38,41], the nuclear stopping [25,40], and the HBT two-particle correlation [36,42].…”
