Subthreshold Antiproton Production in Nucleus-Nucleus Collisions

LI, GQ; Ko, Che Ming; Fang, X. S.; Zheng, Y. M. (American Physical Society, 1994)

Antiproton production in nucleus-nucleus collisions at energies below the threshold for its production from the nucleon-nucleon interaction in free space is studied in the relativistic Vlasov-Uehling-Uhlenbeck model. The ...

Partonic effects on the elliptic flow at relativistic heavy ion collisions

Lin, ZW; Ko, Che Ming. (American Physical Society, 2002)

The elliptic flow in heavy ion collisions at the Relativistic Heavy Ion Collider is studied in a multiphase transport model. By converting the strings in the high energy density regions into partons, we find that the final ...

Kaon Production from Hot and Dense Matter Formed in Heavy-Ion Collisions

Brown, G. E.; Ko, Che Ming; Wu, Z. G.; Xia, L. H. (American Physical Society, 1991)

In heavy-ion collisions, kaons can be produced from baryon-baryon, meson-baryon, and meson-meson interactions. Simple meson-exchange models are introduced to study kaon production from these processes in the free space. ...

Antiproton Production in Ni+ni Collisions at 1.85 Gev/nucleon

LI, GQ; Ko, Che Ming. (American Physical Society, 1994)

Antiproton production in Ni+Ni collisions at 1.85 GeV/nucleon is studied in the relativistic Vlasov-Uehling-Uhlenbeck model. The self-energies of the antiproton are determined from the nucleon self-energies by the G-parity ...

Effects of momentum-dependent nuclear potential on two-nucleon correlation functions and light cluster production in intermediate energy heavy-ion collisions RID A-2398-2009

Chen, LW; Ko, Che Ming; Li, Ba. (American Physical Society, 2004)

Using an isospin- and momentum-dependent transport model, we study the effects due to the momentum dependence of isoscalar nuclear potential as well as that of symmetry potential on two-nucleon correlation functions and ...
