An explanation of the elliptic flow difference between proton and anti-proton from the UrQMD model with hadron potentials
Qingfeng Li, Yongjia Wang, Xiaobao Wang +1
The time evolution of both proton and anti-proton flows from Au+Au collisions at =7.7 GeV are examined by using both pure cascade and mean-field potential vers…
Transport model study of the -scaling for , K, and HBT-correlations
Qingfeng Li, Marcus Bleicher, Horst Stoecker
Based on the microscopic transport model UrQMD in which hadronic and string degrees of freedom are employed, the HBT parameters in the longitudinal co-moving system are investigate…
Analysis of the Fusion Hindrance in Mass-symmetric Heavy Ion Reactions
Caiwan Shen, Yasuhisa Abe, Qingfeng Li +1
The fusion hindrance, which is also denominated by the term extra-push, is studied on mass-symmetric systems by the use of the liquid drop model with the two-center parameterizatio…
Pion freeze-out through HBT correlation in HICs from AGS/FAIR to RHIC energies
Qingfeng Li
In this talk we present the results of two-pion HBT correlation at freeze-out in heavy ion collisions (HICs) from AGS to RHIC energies. The UrQMD hadron-string transport model as w…
Re-visit the N/Z ratio of free nucleons from collisions of neutron -rich nuclei as a probe of EoS of asymmetric nuclear matter
Qingfeng Li, Zhuxia Li, Enguang Zhao +1
The N/Z ratio of free nucleons from collisions of neutron-rich nuclei as a function of their momentum is studied by means of Isospin dependent Quantum Molecular Dynamics. We find t…
Production and rescattering of strange baryons at SPS energies in a transport model with hadron potentials
Qingfeng Li, Zhuxia Li
A mean-field potential version of the Ultra-relativistic Quantum Molecular Dynamics (UrQMD) model is used to investigate the production of strange baryons, especially the s and…
