| Abstract: | PACIAE,a parton and hadron cascade model,is utilized to systematically investigate strange particle production and strangeness enhancement in Au+Au collisions and in Pb+Pb collisions with the SNN~(1/2)= 200 GeV at the RHIC and 2.76 TeV at the LHC,respectively.The experimental results at different centralities,using data from the STAR collaboration and the ALICE collaboration,are well described by the PACIAE model.This may represent the importance of the parton and hadron rescatterings,as well as the reduction mechanism for strange quark suppression,that are implemented in the PACIAE model. |
