摘要：

We present a systematic study of the strange and multistrange particle production in Pb + Pb collisions at sNN=2.76 TeV based on paciae model simulations. Two different mechanisms, namely the single string structure variations and multiple string interactions, are implemented in the simulations. These modifications give rise to an enhancement of the string tension value involved in the Lund string fragmentation framework and generate more strange particles in the hadronic final state. By comparing the simulation results with the ALICE experimen...
